TRANSACTIONS OF THE 



Average Annual and Seasonal Temperature in Sacramento. 



The statement below shows the average temperature, for each year, for 

 thirty -five years; also the spring, summer, autumn, and winter temper- 

 ature for thirty-five years. The coldest year, inferring from the average 

 temperature, was that of 1880, 57.2°; the warmest was 1864, 62.8°; the 

 mean average for the past thirty-five years, 60.2°, showing the coldest to 

 have been 3° below the mean average, while the warmest year was that of 

 1864, when it was 2.6° above the mean average for thirty-five years. By 

 careful study of the table, there will be noticed but a slight difference 

 between the coldest and the warmest year, as compared with a thirty-five 

 years' average, generally not more than 3°. Therefore, we might safely say 

 that the average temperature of any year is not likely to vary more than 

 3° from 60° either way, between the hottest and coldest year, as compared 

 with the mean average temperature for the past thirty- five years:
