CLIMATOLOGICAL TABLES
CONDENSED CLIMATOLOGICAL SUMMARY
In the following table are given for the various sections of the climatological service of the Weather Bureau the monthly average temperature and total rainfall; the stations reporting the highest and lowest temperatures, with dates of occurrence; the stations reporting the greatest and least total precipitation; and other data as indicated
by the several headings. The mean temperature for each section, the highest and lowest temperatures, the average precipitation, and the greatest and least monthly amounts are found by using all trustworthy records available. The mean departures from normal temperatures and precipitation are based only on records from stations that have
10 or more years of observations. Of course, the number of such records is smaller than the total number of stations.
