228 BAILIWICK RAINFALL. 



A sharp thunderstorm visited Alderney during the early 

 morning hours of Sunday, June 27th. At Le Huret station 

 Mr. Picot's gauge collected 0*73 in. of water. The other 

 islands escaped this storm, but some distant lightning and 

 thunder was noted at Guernsey at 3 a.m. 



July was a wretchedly cold month with very big rainfall. 

 The west wind in summer is, speaking comparatively, cold, 

 and throughout July the wind was persistently westerly and 

 frequently fresh or strong in force. Two warm days occurred 

 in the first week, the 3rd and 4th. The latter, both as 

 regards maximum temperature (78*2 deg.) and mean (66*3 

 deg., normal 58*4 deg.) was the warmest day of the year, 

 but onwards from the 6th temperature was continuously and 

 decidedly low. The month's mean temperature was 58*2 deg. 

 against a normal of 60*1 deg. The rainfall total was exces- 

 sive, but only because of two heavy downpours, neither 

 associated with thunderstorms, for comparatively little rain 

 fell anywhere until the 14th. These two heavy falls with the 

 month's total are detailed below.

Both at Sark and Alderney it was the wettest July since 

 observations were begun in 1906 ; at Les Blanches (Guernsey) 

 we have to go back to 1894 to find a wetter July. In that 

 year, however, the total reached the abnormally big figure of 

 6*50 in. ! July's normal is 1*90 in. 



Sark reported a distant thunderstorm on the evening of 

 July 4th, the very hot day already referred to, and a shower 

 fell in that island which yielded 0*08 in. of water in the gauge 

 at Captain Henry's. 



The weather of August divided itself into a rainy first 

 fortnight followed by some very sunny days and no rain at 

 any of the stations from the 15th to the 28th inclusive. No 

 summer heat blaze was experienced, temperature on the whole 

 varying but slightly from the normal. This was the warmest 

 month of the year. 



September was wet as regards its total rainfall — at Sark 

 and Alderney, similarly to July, it was the wettest month of the 

 name of the ten years 1906-1915. This fact notwithstanding 

 September was on the whole an exceedingly pleasant and 

 sunny period. The big rainfall was owing to several heavy
