THE RAINFALL OF GUERNSEY FOR THE 



YEAR 1911. 



BY MR. A. COLLENETTE, F.C .8. 



Although not as wet as 1910, 1911 was wetter than the 

 average. The total was 9 inches less than that of 1910, and 

 0*"68 above the average. 



In this the rule, as far as one lias been established, of the 

 driest year in the period being followed by two successive 

 years of greater rainfall the second of which is the highest 

 of the period and being followed by a considerable drop, has 

 again proved correct. 



As we have now passed the years of minimum and 

 maximum falls, Ave may expect a slight increase for two years, 

 but no very great difference from the average. 



As regards the detail of the year, the months range 

 themselves as 6 dry and 6 wet. June was the only wet 

 summer month, and May, July and August were very dry. 

 October, November and December were very wet, and 

 contributed together 55°/ 0 of the year's total instead of 37°/ 0 . 



December was the wettest month with 8*33 inches. This 

 was just twice its average (4" 16 inches), but was not a record, 

 as this month had a previous record of 11*47 inches. The 

 three wettest months gave progressively increasing falls ; 

 thus October gave 5*4 inches ; November 6*7 inches, and 

 December, 8*3 inches ; a total of 20 inches. 



Of the last 100 days of the year no fewer than 82 were 



wet. 



As regards the distribution of rainfall over the year, 

 June, October, November and December contributed 66°/ Q of 

 the total, leaving only 34°/ Q for the remaining eight months. 

 May and August gave each 1'6°/ D or together 3*2°/ 0 instead 

 of 12°/ Q . These were the least wet. 



There have been changes in the stations contributing 

 returns. For the moment we have no returns from King's 

 Mills, these having ceased at the end of August. On the 

 other hand I am now getting regular returns from St. George 

 [1911.]
