BLUE HILL 1912 WEATHER 



Year Slightly Warmer and Dryer Than 

 Normal, According to Observatory Sta- 

 tistics 



Blue Hill Observatory weather statistics 

 for 1912 show that the year averages slight- 

 ly warmer than normal and, like the four 

 preceding years, was deficient in precipi- 

 tation. The mean temperature of 47.2 de- 

 grees was 0.2 degree above the average 

 as compared with 4T.8 degrees in 1011. The 

 winter was unusually cold and nearly nor- 

 mal temperatures during the spring and 

 summer were followed by a very warm 

 autumn. 



January was the coldest month in twen- 

 ty-four years, and the long continued cold 

 caused the ground to become frozen to a 

 depth of Ave feet in February, a hitherto 

 unrecorded depth for frost in this vicinity. 

 The maximum temperature of the year 

 of 90 degrees on July 9 was the highest 

 temperature in 64 years with the excep- 

 tion of two days in July, 1911, when the 

 same temperature was experienced. The 

 minimum temperature of the year of 11 

 degrees below zero on Jan. 13 was the low- 

 est recorded since 1907. 



The total precipitation of 40.40 Inches 

 was 5.58 inches less than the normal 

 amount, thus making 1912 the fifth consecu- 

 tive year to be dryer than the average. 

 In 1011 the total was 44.62 inches and in 

 1910 it was 34.27 inches. Marked deficien- 

 cies in precipitation occurred in Febru- 

 ary, June, September and October, June be- 

 ing the dryest month of any name on rec- 

 ord at Blue Hill, the total rainfall being 

 only .33 inch. More precipitation occurred 

 In December than in any other month, the 

 total of 5.73 Inches serving to replenish the 

 diminishd water supply. 



Thre was little wind throughout the year, 

 the mean hourly velocity being only slight- 

 ly higher than In 1911 when it was the low- 

 est on record. The prevailing wind direction 

 was west. Maximum velocities of 63 miles 

 per hour were experienced on Feb. 22 and 

 Dec. 30. The mean relative humidity was 

 slightly higher than usual; there was the 

 normal amount of cloudiness and slight 

 excess of sunshine. Snow covered the 

 ground on 60 days and the total fall was 53 

 inches, which is eight inches less than the 

 normal amount.
