THE SUNSHINE OF GUERNSEY FOR THE 

 YEAR 1919. 



The total sunshine, 1,903 hours, differs from the average by 

 5 hours only, being that number of hours in excess. The year 

 must therefore be considered as equal to the average, rather 

 than a sunny year. The months of the year were equally 

 divided as to those which gave more and those which gave less 

 than their average totals. The sunniest month of the year was 

 August, with 261 hours, and the least sunny was December with 

 33 hours. October shewed the greatest departure from the 

 average, with an excess of 49 hours, and «July had the largest 

 deficit of any month, having 40 hours less than the average. 

 The variations of the other months give a mean departure from 

 their averages of 12 hours. Only one record was broken in the 

 sunniest day, September 10th having registered 13 hours this 

 year against a previous record of 12*8 hours. The excess of 

 the sunshine in October, as stated above, was 49 hours, and its 

 total is 11 hours in excess of its previous highest, and therefore 

 constitutes a record. The maximum sunshine of a month 

 rarely exceeds 50% of the possible, but this year there were 

 4 months ranging from 51 to 59%. On the other hand, 

 December had but 13% of the possible. October has the 

 distinction of being the only| month of the year without a 

 sunless day.
