RAINTALL, TEMrERATURES, AND RELATIVES HUMIDITY, 1946 



In the 22 years of record, 1946 was the third driest year. The rain- 

 fall amounted to only 87.38 inches, showing a deficiency of 21.43 inches. 

 This deficiency was most pronounced in the wet season, amounting to 

 17.93 inches. Only 2 months, July and September, had an excess, 

 which, however, was very slight — 0.77 and 0.20, respectively. There 

 was a total deficiency of 3.50 inches in the dry season, January to April, 

 inclusive; only March showed a small excess — 0.25 inch. February 

 was the driest month (0.32 inch) and November the wettest (14.98 

 inches). Table 1 gives the total yearly rainfall, and the station aver- 

 age, for each year from 1925 to 1946, inclusive.

Table 2 gives the rainfall by months for the years 1945 and 1946, the 

 station average for each month, the excess or deficiency for each month 

 and the accumulated plus or minus, and also the maximum rains each 

 month for 5 and 10 minutes, and 1 and 24 hours. These maximum 

 values are consecutive wherever that maximum occurred; hence the 

 24-hour record is not necessarily from midnight to midnight. 



Table 3 gives the number of hours of rain each month for 1946 

 and the total amount in inches, and then these data separated into 

 the four 6-hour periods. These data are of interest in that they indi- 

 cate when most rains may be expected. From 6 a. m. to noon there is 

 less rainfall than from noon to 6 p. m.
