Geographical Introduction

Fresno is the closest major city to the geographic center of California with an estimated 

population of 480,000 people as of early 2007. This places it as the sixth largest city in 

the state. Fresno is located roughly in the east-central portion of the San Joaquin Valley, 

which is the southern half of the Central Valley of California. Fresno lies roughly 

halfway between the sprawling metropolitan areas of southern California and the San 

Francisco Bay and Sacramento metropolitan areas to the north. As a result, a large 

number of people and goods travel through the area to go between or to the population 

hubs of northern and southern California. 

The San Joaquin Valley is generally a flat area with elevations roughly between 100 and 

600 feet in elevation. The foothills of the Sierra Nevada are located about 15 miles east of 

the Fresno which eventually rise to the Sierra Nevada mountains. The Sierra Nevada 

mountains rise to elevations between 12,000 and 15,000 feet along the ‘crest’ which is 

about 80 miles to the east of the city. Some 55 miles to the west lies the Diablo Range, a 

chain of mountains that extends about 2,000 to 3,000 feet high on average. The natural 

vegetation of the San Joaquin Valley and the nearby foothills below 1,000 feet in 

elevation is grass and sagebrush with only a few oak trees mainly along riverbanks. 

However, extensive urban development and agricultural use have significantly altered the 

landscape to where little of it today is native vegetation, especially in areas below 500 

feet in elevation. 

In recent years, the city continues to grow and expand outward from the downtown area, 

especially on the north side. This has resulted in the conversion of a large number of open 

plots of land into residential and commercial developments. The continued growth of the 

city has resulted in an urban heat island effect, most established at night, where 

temperatures run as much as 10°F warmer than outlying agricultural areas. 

History of Weather Observations

Initial weather observations in Fresno were for precipitation only and were made by the 

Southern Pacific Railroad Company. These observations were made starting in January 

1878. Only monthly precipitation totals from the Southern Pacific Railroad Company 

have been incorporated into the Fresno records. These records were considered as part of 

the official weather record for Fresno until August 16, 1887 when the Signal Service 

commenced weather observations in the city. 

 

A letter dating July 27, 1887 was sent to Sgt. J.R. Williams of the U.S. Signal Corps in 

Fort Davis, Texas to proceed to Fresno to open what would become the National Weather 

Service office here. On August 10, 1887 a “nice” office was secured by Sgt. Williams in 

Fresno for a cost of $15 a month. Six days later on August 16th, weather observations 

began by the Army Signal Corps in downtown Fresno at the Taylor Building, located at 

1042 J Street (what is now Fulton Street). These observations consisted of precipitation, 

temperature, humidity, pressure and wind. New instruments were installed at this site on 

October 15, 1887. Observations continued at this location through January 30, 1889. 
2 

On January 31, 1889 observations began at the Hughes Building located at 1011 I Street 

(now Broadway). This was a move of about 420 feet to the southwest of the original site. 

The office lasted a little over a year at this location and on September 30, 1890 took its 

last observations here before moving again. This time the office moved 435 feet to the 

northeast to the Fresno Loan and Savings Bank Building located at 1052 J Street (now 

Fulton Street) and began observations here on October 1, 1890. The office remained at 

the Fresno Loan and Savings Bank Building through January 25, 1895. 

On January 26, 1895 it was time for the office to move to I Street once again. The new 

location was at 1056 I Street (now Broadway) at the Farmer’s National Bank Building. 

This was a move of 380 feet to the southwest of the location at the Fresno Loan and 

Savings Bank. Weather services were transferred from the Army to the U.S. Weather 

Bureau in 1891. Weather observations continued at the Farmer’s National Bank Building 

through April 30, 1913.

location of the National Weather Service’s Fresno office from January 26, 1895 through 

April 30, 1913. A wind vane can be noted on the roof. The above photo was taken on 

April 30, 1896. 

On May 1, 1913, the office was established at the Roswell Building located at the 

southeast corner of Tulare and Van Ness Avenues. This move was 700 feet northeast of 

the Farmer’s National Bank Building site. The office at the Roswell Building was the 
3 

sole observing site and office in Fresno for weather until July 1, 1929. On this date the 

U.S. Weather Bureau opened a second office to support the nation’s growing aviation 

community at Maddux Field Airport at the corner of Barstow Avenue and old Highway 

99. The Maddux Field office moved to 7 miles southeast to Chandler Field, which is 

located on the west side of Fresno, on March 14, 1930. Weather observations continued 

at Chandler Field until March 31, 1935 when the airport office closed. 

Fresno continued to have two offices through the mid 1930s. The “downtown” office 

stayed at the Roswell Building through August 31, 1933. Then on September 1, 1933, the 

“downtown” office made a final move to the Brix Building located at 1221 Fulton Street. 

This location was 700 feet west-northwest of the Roswell Building. 

On March 1, 1939, weather observations began once again at Chandler Field. Later that 

year it was decided to consolidate the airport and “downtown” offices in Fresno and have 

just one location at Chandler Field. On July 1, 1939 the Brix Building location was 

closed and all weather functions in Fresno were transferred to Chandler Field. 

It is important to note that weather observations, particularly of wind, were impacted 

substantially by taller surrounding buildings. This was first noted by the observers on 

August 16, 1887 and noted as a problem through the 1930s. During the period of which 

offices in Fresno were located at both the downtown location and at the airports at 

Maddux Field and Chandler Field, temperature and precipitation records were complied 

from the airport when data was available over the downtown site. This was done as it 

provided a more consistent station sighting and thus a better longer term climate record. 

On August 20, 1949, the Weather office experienced another move, relocating from its 

spot in Chandler Field to the northeast corner of the Fresno Air Terminal (now the 

Fresno-Yosemite International Airport). The move to the Fresno Air Terminal was seven 

miles east-northeast of the location at Chandler Field. After completion of new airport 

facilities on September 1, 1961, the office again moved to the tower building on the 

southwest portion of the Fresno Air Terminal. At the end of January 1986, the office was 

relocated to the corner of Peach Avenue and Dakota Avenue in Clovis, just across the 

street from the airport, however, the official weather instruments remained on the 

grounds of the Fresno-Yosemite International Airport.

On September 1, 1995, an Automated Surface Observation System or ASOS was 

commissioned at the Fresno-Yosemite International Airport. With the commissioning of 

ASOS several changes occurred with the climate records of Fresno. Due to the changes in 

methodology in observing sky cover by ASOS compared to human observers, records of 

cloud cover were discontinued. This includes the removal of a sunshine switch. In 

addition, ASOS is a totally automated system and can not record how much snow, ice 

pellets or hail accumulates. Any accumulating snowfall, ice pellets or hail is measured by 

the Air National Guard unit located on the grounds of the Fresno-Yosemite International 

Airport. In addition, the Air National Guard also has a temperature sensor and standard 

rain gauge to record daily weather observations. These instruments are in place to be used 

as the official back-up for temperature and precipitation data in the event that equipment 

issues arise with ASOS and a need for back-up climate information becomes necessary.

An Overview of Fresno’s Climate

The climate of Fresno is heavily influenced by the mountain ranges that border the San 

Joaquin Valley. The Diablo Range rises to elevations as high as 2,000 to 3,000 feet, is 

located roughly 55 miles to the west of the city, and acts to create a rain shadow effect on 

the San Joaquin Valley and is especially pronounced in areas west of the city on the 

valley floor. The Diablo Range blocks a considerable amount of moisture from flowing 

into the San Joaquin Valley from the Pacific. Influxes of tropical moisture from the south 

are reduced often by the Tehachapi Mountain range, which border the southern end of the 

San Joaquin Valley. The Tehachapis rise to between 6,000 and 8,800 feet in elevation on 

average. As a result of these mountain chains, the climate of Fresno is dry compared to 

other locations in the continental United States. 

During the six month period from November through April, Fresno receives 90 percent of 

its normal annual precipitation, which is 11.23 inches. Often this precipitation falls in 

association with large-scale frontal systems. Winter temperatures are usually mild with 

occasional cold snaps dropping temperatures to or below freezing. However, prolonged 

cold snaps are rare, as winter months feature nighttime fog that usually keeps the 

temperature from dropping to or below freezing. On average, low temperatures of 32 

degrees or below occur 19 times a year. Given the scarcity of cold air necessary for it to 

fall, snow is a rare occurrence, even that of flurries. 
6 

When it’s not raining, the cool season is most known for its fog. The typical fog season 

runs from late November through mid February during the time of year when daylight is 

the shortest. Fog lasting for several continuous days is not unusual during this time of the 

year; often sunlight may only be noticeable for a few hours of the day – if that. Periods of 

fog lasting nearly two weeks are common in many cool seasons. During these times, fog 

will lower to the valley floor at night dropping visibility to below a quarter of a mile and 

then rise during the day to at best a few hundred feet above the ground. This gives the sky 

the appearance of heavy, solid cloud layer. Dense fog, or that where the visibility drops to 

or below a 1⁄4 of a mile, is known as “Tule (too lee) fog” locally; the name is derived from 

the Tule reeds once prevalent in the valley marshes. 

Spring represents the transition between the winter storm season and the hot and dry 

summer. During the springs, weak fronts will bring light rainfall amounts to the area and 

often are known for creating gusty winds ahead and behind their passage. In years when 

winter precipitation is minimal, blowing dust becomes a common issue on days when the 

wind picks up. 

Summers in Fresno are characterized by abundant sunshine and hot temperatures. Clouds 

are typically only seen during the afternoon and evening hours over the Sierra Nevada 

while across the San Joaquin Valley full sunshine prevails. Temperatures frequently 

reach into the triple digits on the hottest days, and in the hottest years reach or exceed the 

110°F threshold. During the summer months of June, July and August, Fresno averages 

at least 95 percent of the total possible sunshine in each month. Rainfall, while 

infrequent, does occur, but amounts are usually light. However, June has had the 

distinction of producing some of the greatest amounts of rainfall in a short duration of 

time. 

Winds in the San Joaquin Valley often flow with the axis of the valley and thus blow 

frequently from the northwest. During the summer, a beneficial feature of these northwest 

winds is the increase in speed during the evening hours that often moderates 

temperatures. Humidity values during the summer months are usually low, with values 

averaging between 20 and 25 percent during the hot late afternoon. 

During the fall, a subtle trend toward cooling takes place as well as the return of 

precipitation. Frontal passages tend to become more common by the later half of October 

and by November usually bring the first widespread wetting rains of the season. 

Thunderstorms can occur in any month of the year. Cool season thunderstorms are noted 

for often being “post frontal” and occurring in any pockets of instability that exists after a 

cold frontal passage. These thunderstorms often produce small hail as well as cold air 

funnel clouds. Tornadoes, while infrequent, have occurred in the city and surrounding 

areas. The most noteworthy tornado in the history of the city occurred on February 20, 

1980 when a tornado hit the Fresno Air Terminal, damaging it along with several nearby 

neighborhoods.

Greatest Intensity Precipitation For 

Specified Time Periods

(September 1887 – November 1986)

Intensity precipitations records were discontinued after November 1986 due to the 

removal of equipment necessary to compile this type of weather record. Although ASOS 

is capable of computing precipitation totals for specified short duration time intervals, 

these values were not incorporated into the records listed below due to the gap in the 

records since November 1986.

Notes: Period of record for dense fog extends back to October 1910. 

Observations were not used for this database prior to October 1910 as 

information in the old climate log books did not distinguish between days 

with dense fog and fog. Records above include days with dense or heavy fog 

as reported in the climate log books and LCDs for Fresno. Prior to 1943, 

dense fog was recorded as having visibility less than 5/16ths of a mile. 

Numbers in bold face and underlined represent the extreme highest value for 

the period of record while numbers in italic, bold font represent the extreme 

minimum for the period of record.

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.
