THE SUNSHINE OF GUERNSEY FOE 18 99. 



BY MR. A. COLLENETTE, F.C.S., F.R. MET. SOC. 



I now have six years' sunshine recorded. It is still too 

 small a period for an average, so that it will be necessary for 

 us to remember that fact while drawing conclusions from the 

 comparison of the mean of the six years and the sunshine 

 of 1899. 



The year 1899 has been the sunniest we have so far 

 recorded, having exceeded 1898, the next sunniest, by 124 

 hours. The following months were sunnier in 1899 than in 

 any of the previous years : February, March, June, July and 

 August. Only one month has been less sunny than in the 

 previous years, viz. : April. The sunniest month of the 

 whole period was last July, when 339*93 hours were recorded, 

 as 484 hours is the number of hours in July during which the 

 sun is above the horizon, it follows that the month gave us 

 70% of the possible sunshine.
