THE RAINFALL OF GUERNSEY.

 have it, is erratic. If periods exist they will be found over 

 longer intervals of time.

The chief peculiarities of the year has been the excessive 

 wetness of February and November and the dryness of 

 May, July and September. 



The months May to October inclusive alternate as though 

 influenced by a regular wave motion. October has been 

 proved to be the wettest month of the year, and that place 

 it still occupies in the 58 years' average. During the last 

 four years, however, it has been less wet than January, 

 February, November and December. In the 58 years' 

 average, June is the driest month, but during the last four 

 years July has taken its place. Again, May and June, the 

 two driest months in the 58 year average, have during the 

 last four years proved wetter than March and April. All 

 these facts point to some changes in progress, the meaning of 

 which we have not discovered.
