NOAA TECHNICAL MEMORANDA 

National Weather Service, 

Western Region Subseries

The National Weather Service (NWS) Western 

Region (WR) Subseries provides an informal 

medium for the documentation and quick 

dissemination of results not appropriate, or not 

yet ready, for formal publication. The series is 

used to report on work in progress, to describe 

technical procedures and practices, or to relate 

progress to a limited audience. These Technical Memoranda will report 

on investigations devoted primarily to regional and local problems of 

interest mainly to personnel, and hence will not be widely distributed. 

Papers 1 to 25 are in the former series, ESSA Technical Memoranda, 

Western Region Technical Memoranda (WRTM); papers 24 to 59 are in 

the former series, ESSA Technical Memoranda, Weather Bureau 

Technical Memoranda (WBTM). Beginning with 60, the papers are part of 

the series, NOAA Technical Memoranda NWS. Out-of-print memoranda 

are not listed. 

Papers 2 to 22, except for 5 (revised edition), are available from the 

National Weather Service Western Region, Scientific Services Division, 

125 South State Street - Rm 1311, Salt Lake City, Utah 84138-1102. 

Paper 5 (revised edition), and all others beginning with 25 are available 

from the National Technical Information Service, U.S. Department of 

Commerce, Sills Building, 5285 Port Royal Road, Springfield, Virginia 

22161. Prices vary for all paper copies; microfiche are $3.50. Order by 

accession number shown in parentheses at end of each entry.

Introduction 

 Reno is located in far-west central Nevada in the lee of the Sierra Nevada 

mountain range. Reno is on the boundary between two distinct climatic regimes. The 

first regime is the dry high desert climate of the western Great Basin. The second regime 

is that of the alpine Sierra Nevada. Both regimes greatly influence Reno’s climate. 

 As a result of its location in the high desert of the Great Basin, Reno experiences 

large temperature ranges on both a diurnal and an annual scale. During the summer 

afternoon highs are often above 90° F, but at night the air mass can cool down into the 

50s. In the last five or six years however, nighttime lows during July and early August 

sometimes do not make it below 65° F. As will be seen in the tables in the Temperature 

section below, this warming trend has been seen in summer high temperatures, but not to 

the extent that it is reflected in the nighttime temperatures. 

These conditions may be due to an urban heat island effect. Since the early 1940s 

the official observation site for Reno has been the airport. When the airport became the 

official observation site on September 1, 1942 the airport was a few miles southeast of 

town in a rural area. There was a noticeable cooling in the average temperatures during 

the 1940s from what had been seen during the 1930s when the observation site was 

downtown. Average temperatures have shown a gradual warming trend over the decades. 

This consistent warming may be due to the fact that the city of Reno has grown in area 

and now surrounds the airport. The weather observation site is now in an urban area, and 

thus the air mass (especially during summer) has a more difficult time cooling down at 

night. 

This warming has not been seen as much during the winter as daytime highs are 

usually in the 40s to lower 50s, and nighttime lows in the 30s. These winter readings 

have been fairly consistent throughout the decades without showing any appreciable 

trends. 

 Precipitation data clearly shows the influence of the Sierra Nevada to the west. 

There is a definite rain shadow effect that is seen in Reno’s precipitation and snowfall 

data. Some locations in the Sierra receive ten times the precipitation that Reno receives. 

The precipitation that occurs at those higher elevation locations is mainly from snowfall. 

Most of Reno’s precipitation falls from November through March. This is a combination 

of rainfall and snowfall. Reno receives an average of 7.48 inches of precipitation per 

calendar year (1971-2000 normals). Of this annual total, 5.01 inches (67%) falls during 

the six-month period from November through April. The warm half of the year is 

relatively dry, with a secondary precipitation maximum in May. 

 An average of 23.5 inches of snow falls in Reno annually, mainly from early 

November through March. Early-autumn and late-spring snows are rare. The 

precipitation shadow (or snow shadow) effect can be seen with this data as well. Where 

mountainous locations to the west receive up to ten times the precipitation that Reno 

records, they get up to 20 times the snowfall. Some locations in the higher elevations, 
2

such as cooperative observing sites and ski resorts, can receive 400 inches or more of 

snow from a snowfall season that can last from mid October through late April. As with 

many locations in the western United States, this “white gold” in the form of a deep 

snowpack, provides much of the water that people use in cities, for industry, and for 

agriculture. However, a decrease in snowpack can adversely affect a wide range of users, 

from ski resorts and other tourist industries, to water and electric utilities, and the public 

at large (Barry, 2005). 

Change in location of weather observing sites 

The climate record for Reno, Nevada extends back to 1870, and the official 

observation site has moved occasionally during that period. By referring to U. S. 

Weather Bureau / National Weather Service (NWS) Local Climatological Data (LCD) 

Annual Summaries for Reno, a chronology of weather observation station moves can be 

derived. 

From December 1, 1870 until December 31, 1887 daily rainfall data was collected 

by the Southern Pacific Railroad Company agent at the rail depot in Reno. Starting on 

January 1, 1888 and continuing through November 10, 1905, maximum and minimum 

temperature data, and precipitation data, were recorded at the Administration Building 

(Morrill Hall) on the University of Nevada campus north of town. 

The U.S. Weather Bureau took over official observations for Reno on November 

11, 1905. The Weather Bureau’s first observation site was at the Thoma-Biglow 

Building, on the northwest corner of First and Virginia Streets, and continued here until 

February 28, 1910. Starting on March 1, 1910 and continuing through February 28, 1934 

weather observations were taken at the I. O. O. F. (Independent Order of Odd Fellows) 

Building on the southeast corner of Second and North Center Streets. The final 

downtown location was at the Post Office Building on the northeast corner of South 

Virginia and Mill Streets. Weather observations were taken here from March 1, 1934 

through August 31, 1942. 

In order to assist the growing aviation industry, weather observing stations were 

opened at airports along the nation’s transcontinental air routes (Whitnah, 1961). The 

Weather Bureau’s station at Reno’s airport (then called Hubbard Field) opened on 

January 8, 1931. Twenty-four-hour duty, along with hourly weather observations and 

upper air observations, started at this time. However, weather observations were now 

being taken at two locations concurrently (Hubbard Field and the downtown Post Office). 

This situation continued from January 8, 1931 through August 31, 1942 (when the city 

Weather Bureau office at the Post Office Building was closed). On September 1, 1942 

the airport became the official observation site for Reno. This airport continues to be the 

official weather observation site to this day. 

The transfer in the official observation site to the airport constituted a change to a 

location a few miles outside of town (actually 3.5 miles south southeast of the Post 

Office). However, the airport was "farther away", so to speak, then than it is now. In the 
3

1930s and early 1940s this area was rural. The city of Reno has expanded in area over 

time and the Reno-Tahoe International Airport is now surrounded by an urban area. This 

difference between the two locations can be seen with precipitation, and especially 

temperature, data for Reno. There was a continual rise in average annual temperatures 

from the late 19th century through the 1930s (a gradual evolution from wood structures to 

brick and stone buildings and paved roads in town?). During the 1940s the average 

temperature was conspicuously less than it had been (since the readings were now being 

taken in a rural area). Average temperatures then started a gradual warm-up, with 

impressive rises during the 1980s and 1990s (urban heat island effects). In a strongly 

developed heat island, the temperature in the urban area can be up to 10°F greater than it 

is in the surrounding rural areas (Oliver and Hidore, 2002). 
4

Climate normals 

 Reno experiences a fairly typical continental climate. There are four seasons, but 

spring and fall can sometimes be short. It might be more accurate to describe two main 

seasons (warm and dry, and cool and wet) with two transition seasons. In explaining the 

short spring seasons in middle-latitude dry climates, Trewartha and Horn (1980) state that 

“[b]ecause the ground is usually dry and lacks much snow, the arrival of spring is 

relatively sudden, and the warm season advances rapidly”. 

 This continentality is reflected in the diurnal temperature ranges experienced 

throughout the year. During winter and the period of lower sun angle and relatively 

higher humidity values, the normal daily temperature range can be 20 to 25 degrees, with 

lows in the 20s and highs in the 40s. The ranges are even higher during the warmer 

months due, again, to the higher sun angles and generally lower relative humidities. 

Daytime highs are usually in the 90s during July and August. Nighttime lows drop into 

the 50s to lower 60s. One caveat should be noted: the 1971-2000 climate normals for 

Reno list low temperatures in the lower 50s during July and August. However, during 

the last five or six years nighttime lows have typically been in the upper 50s to lower 60s. 

This may be a result of increased urbanization adjacent to the official observation site at 

the Reno-Tahoe International Airport. 

 As mentioned above, Reno experiences dry summers and wet winters. This 

annual precipitation regime is often referred to as a “Mediterranean climate” (Warner, 

2004). In fact, at Reno 4.66 inches of precipitation (62% of the annual total of 7.48 

inches) is recorded during the months of November through March (1971-2000 normals). 

Only 2.47 inches of precipitation is recorded during the drier half of the year (May 

through October). 

 Much of the precipitation during the colder half of the year falls as rain. But 

Reno does receive snow during the winter. During the snowfall season (typically 

November through March) Reno sees nearly two feet of snow (23.5 inches). In the 

foothills west of the city, however, residents may see three to four times this amount. 

 A study of degree days can be instructive. During a typical year Reno records 

5600 heating degree days (HDDs), spread throughout the year, from highs of 987 in 

December and 984 in January, to a low of 12 HDDs in July. The 1971-2000 normals for 

cooling degree days (CDDs) clearly show the mild summer nights that Reno residents 

have experienced up until the last decade or so. Reno averages only 493 CDDs 

throughout the year (more than an order of magnitude less than the yearly total of HDDs). 

However, as discussed above, this may change in the future. Reno may start to record 

more CDDs during the year if nighttime temperatures continue their warming trend. This 

may be reflected in the future 1981-2010 normals. 

 The following tables list the monthly climate normals for Reno.

Temperature 

Daily temperature records 

 As mentioned in the discussion on normal temperatures above, Reno typically 

experiences a normal temperature range of 20 to 25 degrees during the winter. The daily 

temperature ranges are even greater during the summer, with ranges of 30 to 35 degrees. 

 Extreme temperatures also show the influence of Reno’s continental location. 

Record high temperatures of 100°F to 108°F have been recorded from mid June through 

early September. The record high of 108 occurred on back-to-back dates (July 10 and 11, 

2002). Of course there have been anomalously warm conditions during other years also. 

The next highest temperatures, 106 degrees and 105 degrees, occurred during the warm 

July of 1931. This July is the warmest of the twentieth century in Reno. However, it is 

only the sixth warmest on record. As can be seen below in the list of warmest Julys at 

Reno (p. 41), the five warmest Julys have all occurred during the twenty-first century. 

Records that are not followed as much by the public are maximum nighttime low 

temperatures. Reno has seen an increase in warm nighttime temperatures through the 

1990s, and especially during the twenty-first century. Of temperature data for the 31 

dates in July, the record warm minimum readings on fully 18 of those dates have 

occurred from 2001 through 2006. The highest minimum temperature ever recorded at 

Reno occurred during the impressive warm spell in July 2006. On the morning of July 

23rd the temperature only dropped to 77 degrees. With so many warm nighttime readings 

during the last few years, this seems to be a trend that residents may have to expect in the 

future. 

 These warm nighttime temperatures contribute to these months being some of the 

warmest on record. For ten straight days during the last half of July 2006 the nighttime 

temperature did not drop below 65°F. During both July 2003 and July 2005, the 

temperature remained above 65 degrees for eight straight days. July 2005 also saw ten 

straight days when the temperature rose above 100°F. With an average monthly 

temperature of 80.0°F, it is easy to see why July 2005 is the warmest month on record at 

Reno. 

 Extreme temperatures during the winter are also indicative of a high desert 

location. The lowest temperature ever recorded at Reno is -19°F which occurred on 

January 8, 1890, during one of the coldest winters in Reno’s history. The temperature 

dropped to -18 on either side of this date, on both the 7th and the 9th. It was extremely 

cold during the day also with the temperature only rising to 6 degrees above zero on 

January 7 and up to +7°F on January 8. 

 Another cold period occurred during late January 1949. On ten consecutive days 

the temperature dropped to below zero, the longest such period in Reno’s history. 

Another cold period was during January 1937 when the temperature dropped to below 
18

zero seven days in a row. January 1949 and January 1937 are the coldest and second 

coldest Januaries, respectively, in Reno’s history. January 1890 is the third coldest on 

record. These are not only the coldest Januaries, but they are also the three coldest 

months on record. In fact, they are the only three months in Reno’s history that have 

monthly average temperatures of less than 20°F. 

Because of the relatively dry air over the region, record highs during the winter 

are mainly in the upper 60s. The record high for January in Reno is 71° which occurred 

on January 31, 2003. January 2003 is the warmest January on record at Reno. 

 The following tables list daily temperature records for Reno from January 1888

Frost / Freeze data 

 This study of frost / freeze conditions looks at temperature data for Reno from 

winter 1906 through summer 2006. This coincides with the period of time that the U. S. 

Weather Bureau, and later the National Weather Service, has been responsible for 

weather observations for Reno. Actual physical observation forms were also available 

for this period, thus alleviating the problem of missing data in automated search engines 

containing climate data for Reno. 

 The Glossary of Meteorology defines a “frost-free season” as the “period, usually 

expressed in days, between the last observed occurrence of frost in the spring and the first 

observed occurrence of frost in the autumn” (Glickman, 2000). In its definition of a 

“growing season” the Glossary of Meteorology further states that, as another measure of 

the growing season, “the frost-free season, is defined as the interval between the last and 

first occurrences of 32°F temperatures in spring and fall”. 

 The National Weather Service defines a “freeze” as occurring “when the surface 

air temperature is 32°F or below over a widespread area for a climatologically significant 

period of time (greater than one hour)” (U. S. Department of Commerce, 2005). 

 For this study the length of a frost-free period is defined as the number of days 

between the date of the last 32°F temperature in the spring and the date of the first 32°F 

temperature in the fall. Thus, if the last 32° temperature in the spring was on May 20th

and the first 32° temperature in the fall was on October 11th, then the frost-free period 

(the actual days that did not experience a 32° temperature) would extend from May 21st

through October 10th. 

 As might be expected, during the last 100 years there has been a large interannual 

variation in the length of the frost-free seasons. Some years have had frost-free periods 

of over 150 days (approximately 5 months) while other years have had frost-free periods 

of less than 90 days. 

The Reno airport became the official weather observation site on September 1, 

1942, after being located in town for the previous fifty years. This change to a rural 

location had a profound effect on weather observations for Reno (more so than with any 

other change in observation site). From 1906 through the 1930s the date of last 32° 

temperature in the spring remained fairly steady with the date usually in May. This 

changed some in the warm decade of the 1930s when the last spring frost occurred in 

mid- to late April. The date of first frost in the fall typically occurred from late 

September to mid October through the 1930s. 

 A dramatic change can be detected after the observation site was moved to the 

airport southeast of town. Starting in 1943 (the first full year that observations were 

taken at the airport) the date of last frost in the spring shifted a full month later - going 

from an average of early May to early June. In the twenty years from 1943 through 1962 
59

the date of last 32° temperature was in June in all but six years (five of those years being 

late in this twenty-year period – 1956, 1957, 1958, 1959, and 1961). 

 This same trend to shorter frost-free seasons was also reflected in the dates of first 

32° temperature during the fall. For the same twenty-year period referred to above (1943 

through 1962) the date of first frost was in September in all but five years. Incredibly, in 

three of those years the first 32° temperature was reported in August. 

By the 1970s we started to see dates of first and last frost starting to resemble 

those that were recorded before the change in observation location in the early 1940s. 

Dates of last 32° temperature in the spring were usually in May, with the date of last 32° 

temperature in the fall again occurring from mid September to mid October. 

 Another change began in the late 1980s to early 1990s. Dates of last frost in the 

spring started occurring in April. In fact, from 1987 through 2006 these events occurred 

during April in nine of those twenty years. This trend is even more impressive in relation 

to dates of first frost in the fall. From 1987 through 2005 (last year available) the date of 

last 32° temperature occurred during October in 17 of those 19 years. During the other 

two years this occurrence was on September 30 (1995) and November 3 (1992). This 

November 1992 date is the only time (from 1906 through 2005) that the first 32° reading 

in the fall occurred in November! 

 In studying data for the 30-year period of 1971-2000 it is found that the average 

date of last 32° temperature in the spring was May 21 while the date of first 32° 

temperature in the autumn was October 3. Data for the most recent 15 years (1991-2005) 

shows that the frost-free period has lengthened. For this period the date of last 32° 

reading was May 3, and the date of first 32° reading in the autumn was October 19. Thus 

the average length of the frost-free period grew from 134 days (for 1991-2000) to 168 

days for the most recent 15-year period – an increase of a full month. 

 As opposed to a date on which frost occurs, a hard freeze is sometimes defined as 

occurring on a date when the temperature drops to 28°F. This reflects the fact that, 

because of radiational cooling at night, the temperature near the ground can be a few 

degrees colder than the temperature that is recorded at the standard observation height of 

around 5 feet above the surface. Thus, even if the official low temperature at night is 28° 

(or 32°) the temperature at the surface may be colder than this official reading. 

 The following two tables list data for last and first 32° temperature during a year, 

the resulting frost-free period (using the definition above), and the last and first 28° 

temperature during each year.

Precipitation 

 Reno is located in the high desert of the western Great Basin. Reno is also 

located in the lee of the Sierra Nevada. The combination of Reno’s high elevation, and 

its protection from the prevailing westerly flow of the mid-latitudes, accounts for Reno’s 

dry climate. With no large bodies of water in the local vicinity of Reno, moisture that 

becomes precipitation must be advected into the region. This is true of most continental 

locations (Sellers, 1965). Reno receives an average of 7.48 inches of precipitation each 

year (1971-2000 climate normals). Two-thirds of this total is received during the sixmonth period from November through April. 

A major reason for this cold season maximum is that “the precipitation is derived 

from the numerous depressions moving eastward from the Pacific coast which result in 

widespread rains” (Trewartha, 1981). Houghton mentions something similar when he 

states that in the Great Basin “precipitation is cyclonic from October to June, but mainly 

convective from July to September” (Houghton, 1969). 

 Reno tends not to receive large amounts of precipitation during a short period of 

time. In studying daily precipitation data for Reno for the period January 1906 through 

summer 2006, precipitation of an inch or greater has occurred on only 54 days. Over two 

inches of precipitation has occurred on only two dates. Heavy precipitation is mainly a 

wintertime phenomenon. Houghton et al. (1975) state that, “near the western border of 

Nevada, precipitation is concentrated in the winter season of Pacific storms”. 

More than half of the fifty-four dates that had precipitation of an inch or greater 

(twenty-nine, or 54%) occurred during December and January. Of these twenty-nine 

dates, nearly two-thirds (eighteen) consisted of rain, either mostly or entirely. The other 

nine December/January heavy precipitation events were either mostly or entirely snow. 

Two of the dates, from Dec. 2001 and Dec. 2002, occurred during the period (1996 

through spring 2004) when snowfall data was not available for Reno (see discussion in 

snowfall section below). 

The wet half of the year also corresponds to the colder months. Reno’s wettest 

months (with precipitation of 4.00 inches or greater) have all occurred from November 

through March. The wettest months, however, do not always match the snowiest months. 

Reno’s annual precipitation has ranged from as little as two inches to as great as 

approximately 15 inches. Because of this large interannual variability, it is most helpful 

to consider precipitation data from as long a period as possible (Landsberg, 1966). 

Precipitation data in this climatology for Reno extends back more than 100 years. 

 The following tables list various information derived from Reno’s precipitation 

data. Precipitation records for Reno extend back to 1870 when the Central Pacific 

Railroad started collecting precipitation data for the area. Fairly reliable monthly records 

of precipitation date from 1870, but continuous daily data is available mainly from 1906 

after the Weather Bureau started recording weather observations for Reno. This 

information will be reflected in the data tables below. 
65

These tables detail the largest precipitation amounts recorded for a calendar day, 

the wettest and driest months from 1870 until present, wettest and driest calendar years 

and water years, and wettest and driest seasons. Other tables list the longest periods of 

consecutive days of precipitation of various amounts, and longest periods during which 

no measurable precipitation was recorded at Reno.

Excessive storms 

For the purposes of this publication an “excessive storm” is defined as a period of 

consecutive days during which measurable precipitation is reported on each day, and the 

total precipitation for the period equals or exceeds 2.00 inches. Authors of other 

climatologies have defined excessive storms using different criteria (Masters-Bevan, 

2000; Staudenmaier, et al., 2002). A location which receives a larger annual precipitation 

total than Reno would typically define an excessive storm with larger precipitation 

criteria. As a result of its dry climate, Reno tends not to receive precipitation during long 

periods of consecutive days. And the daily precipitation that Reno does receive is often 

of a relatively small amount. 

As the following table shows, since 1906, an excessive storm of 2.00 inches of 

total precipitation or greater has occurred on only twenty-one occasions at Reno (an 

average of only once every five years).

Snow 

 Reno receives an average of 23.5 inches of snowfall each year (1971-2000 

normals). Ninety percent of this total is received during the five-month period from 

November through March. 

 Accurate daily snowfall records for Reno generally begin in 1906 after the 

Weather Bureau took over responsibility for weather observation in Reno. Monthly 

snowfall data back to 1893 has been derived from historical data listed in Local 

Climatological Data sheets for Reno from the early 1950s. 

It should be noted that Weather Bureau (and later National Weather Service) 

personnel took weather observations (including measurements of snowfall amounts) up 

until the mid-1990s when an automated weather observing system was installed at the 

Reno airport. This system did not measure snowfall. It was soon realized that snowfall 

data was an important component of climate information. In order to remedy this, in the 

spring of 2004 a cooperative observer near the airport was engaged to supply daily 

snowfall data again for Reno. 

 Reno does not often experience significant snowfall at the airport. However, in 

the foothills west and north of the Truckee Meadows (where the city of Reno is located) 

residents can receive large amounts. When Reno receives six inches of snow in the 

valley, there can be up to two to three feet of snow measured in the foothills at around 

5,000 feet elevation. Thus Reno’s airport snowfall amounts do not reflect what can be 

experienced in other parts of the city, especially at higher elevations. This is similar to 

other locations throughout the mountainous western United States. 

The following tables list various information derived from Reno’s snowfall data. 

In these tables may be found information relating to the largest snowfall amounts 

recorded for a calendar day at Reno, the snowiest and least snowy months from 1870 

until present, wettest and driest calendar years and water years, and wettest and driest 

seasons. Other tables list the longest periods of consecutive days of precipitation of 

various amounts, and longest periods during which no measurable precipitation was 

recorded at Reno.

Excessive snowstorms 

For the purposes of this publication an “excessive snowstorm” is defined as a 

period of consecutive days during which measurable snowfall is reported on each day, 

and the total snowfall for the period equals or exceeds 15.0 inches. As with the definition 

of excessive storms, authors of other climatologies have defined excessive snowstorms 

using different criteria (Staudenmaier, et al., 2002). A location which receives a larger 

annual snowfall total than Reno would typically define an excessive snowstorm with 

larger snowfall criteria. 

As the following table shows, since 1893, an excessive snowstorm of 15.0 inches 

(or greater) of total snowfall has occurred on only twenty-two occasions at Reno.

Acknowledgments 

I would like to thank Jim Fischer, Science and Operations Officer, and Jane 

Hollingsworth, Meteorologist-in-Charge, both at the National Weather Service Forecast 

Office in Reno, for providing encouragement while this project was being undertaken. 

Thanks also to Mark Mollner, Scientific Services Division at NWS Western Region 

Headquarters, for thoroughly reviewing the manuscript and providing many helpful 

suggestions. 

Finally, I would especially like to thank the staff at WFO Reno (and also those 

who worked at the previous U. S. Weather Bureau and NWS station locations in Reno), 

especially the Meteorological Technicians, Hydrometeorological Technicians, and 

Meteorological Interns, who, over the decades, collected and archived the data from 

which this climatology was compiled. Without their dedicated and conscientious service 

over the last 100 years, the completion of this project would not have been possible.
