THE SUNSHINE OF GUERNSEY FOR THE 

 YEAR 1913. 



BY MK. A. COLLENETTE, F.C.S. 



The year 1913 has been a year of great gloom. The duration 

 of sunshine has fallen off so that the record for gloom has 

 again been broken. 



It will be remembered that, as far as Guernsey is con- 

 cerned, 1912 proved to total less sunshine than any of the 

 preceding nineteen years, but bad as was 1912 with 1,704 

 hours instead of 1,925, which had been our average, 1913 

 has fallen below and has totalled 1,691 hours only. 



I have therefore to draw the attention of the Society 

 not only to a lowered average but to a greater range. 



The average during the last three years has been brought 

 down from 1,925 to 1,905 hours. The range of sunshine, that 

 is the difference between the sunniest and the least sunny year 

 was, three years ago, 490 hours ; noAv the range is 524 hours. 



It will be seen by the tables published that the falling off 

 is almost entirely in the summer sunshine, or it may be stated 

 as follows : " The winter months have been a little below their 

 averages, but the summer months have been markedly below." 

 Still this is not true of the separate months, for some have 

 exceeded their averages, but not to the extent of counter- 

 balancing the gloomy months. February was 11 hours over 

 its average. January, March, April, May, June, July, 

 August and September, that is 8 out of 9 months, lost 366 

 hours. October, November and December helped February 

 in lessening the loss, their excesses reducing the year's total 

 loss to 204 hours. 



Two records have been made by the separate months. 

 April's total is the lowest so far recorded and October's 

 total the highest.
