THE SUNSHINE OF GrUEKNSEY FOE THE 

 YEAR 1916. 



BY MR. A. COLLEXETTE, F.C.S. 



The distribution of sunshine, as regards the monthly totals, 

 offers some unusual features. 



The first three months of the year were all below their 

 averages, so that collectively there was a loss of 73 hours. 

 April on the contrary was very sunny and exceeded its 

 average by 40 hours, and reduced the accumulated deficit to 

 33 hours. 



The next three months, May, June and July, each showed 

 a deficit of which June's was the greatest with 3tf hours and 

 collectively reached 60 hours. August gained seven hours 

 over its average. September and October both proved 

 months with deficits, amounting to 57 hours. November was 

 normal and December showed a gain. 



The year, therefore, was behind the average all the year 

 through the gains being insufficient to bring the total, at any 

 time, up to the average. 



With the exception of April and December the months 

 have been characterised by deficient sunshine. 



It will be remembered that I drew attention to the fact 

 that June, both in the actual totals of the years and in the 

 averages, seemed to occupy a lower position than its place 

 in the solar year demanded, and I promised to investigate the 

 matter and discover if the deficit was the result of the 

 arbitrary divisions of the calendar year or a real phenomena. 



That I have done, but I have found it difficult to work 

 the solar year while retaining the positions of the months in 

 the calendar year. 



The plan finally adopted, as the one introducing fewest 

 errors, was to make the year start from the shortest day in 

 December to the longest day in June, giving 30 days to each 

 month and placing the odd days in December and January, 

 for at that period of the year the daily sunshine is so small 

 that these days do not affect the main issue. So arranged, the 

 position of June in the averages works out as high as May,
