THE KAINFALL OF GUERNSEY FOR THE 

 YEAR 1919. 



BY A. COLLENETTE, P.C.S., 



Director of States Meteorological Station. 



The year 1 919 lias proved to be a wet year. Its total rainfall 

 is 45'57 in. Four months have been dry and eight wet. The 

 dry months were May, June, July and October. These 

 months gave a joint deficit of just under five inches (4*97). 

 The combined excess of the eight wet months was nearly 14 

 inches (13*79) ; the mean difference being 8'82 in. This 

 distribution shews that the summer was dry, and the winter 

 months wet. The three first months provided the excess of the 

 year within a small fraction (8*59 out of 8\S2). It follows, 

 therefore, that the wetness of the year was entirely due to the 

 excessive rainfall of these mouths. October, usually the 

 wettest month of the year, was particularly dry with a deficit 

 of 2*38 in.; but as regards actual rainfall, the two driest months 

 were May and June, which together shew a deficit of 2*19 in. 



The wet days, on the other hand, shew an excess of one 

 only over the average. Four months (January, February, 

 November, December) together gave 101 out of the 187 wet 

 days. In this also it will be seen that the winter months 

 provided the excessively Avet days. On the whole, the number 

 of wet days is equal to the average. Besides providing an 

 excessive number of wet days, these four months also shew 

 single days of large rainfall ; but the greatest rainfall in one day 

 fell on September 2nd (2*30), and this fall gave two-thirds of 

 the rainfall for that month. 



The wettest day of the year was Septembar 2nd as stated. 

 The rain measured on this day at the various Stations was as 

 follows : — 



Brooklyn 2'30" Rohais 2'32" Rectory, St. Martin's 2-23"
