74 BAILIWICK RAINFALL. 



another thunderstorm, reported as heavy, and accompanied by 

 much rain, passed over Alderney. 



Very unsettled weather prevailed all through November, 

 which was also a very mild month. Rainfall was especially 

 heavy in the first half and thunderstorms again occurred at 

 Alderney and Guernsey, with hail squalls, during the night 

 from the 5th to the 6th and again on the 10th, at Guernsey 

 on the 11th, and at Alderney on the 13th and 14th. At Sark 

 and Alderney November was the second wettest month of the 

 year. 



The persistent mild weather experienced all through 

 October and November continued until past the middle of 

 December, when temperature became variable and the month 

 ended up cold. A big cyclonic rain fell on the 5th, totalling 

 as much as 1*14 in. at Guernsey, 0*95 in. at Sark (the year's 

 heaviest fall in that island), and 0*76 in. at Alderney. After 

 a comparatively dry fortnight as regards the actual amount of 

 rain the weather again became increasingly unsettled just 

 before Christmas, and at Alderney a snowstorm yielding 

 0'15 in. of water occurred on the 31st. This amount of water 

 represents roughly H inches of snow. 



This year, the shortest day, December 21st, was marked 

 by brilliant sunshine, the sun shining down from a cloudless 

 sky from morning to night. The same thing by the way 

 occurred in 1891, and again in 1904. On the other hand from 

 1908 to 1912 inclusive (for five consecutive times) the shortest 

 day was sunless at Guernsey. 



In conclusion I have pleasure in once more acknowledging 

 the much valued help of Capt. Henry, of the Vallee du Creux, 

 Sark, and of Mr. W. J. Picot, of Le Huret, Alderney, who 

 each in their respective islands have now for eight years taken 

 rainfall observations and sent me weekly returns of the mea- 

 surements. Their records form, without doubt, an interesting 

 as well as valuable supplement to those taken at Guernsey. 



Absolute Droughts in 1913. 

 An Absolute Drought, as defined in British Rainfall, is 

 "a period of more than 14 consecutive days, no one of which 

 is a rain day." 



No Absolute Drought was registered in any of the 

 islands. 



Longest Absolutely Dry Spell, 1913. 



Sark February 17 to 28 = 12 days. 



Alderney July 16 to 29 ... = 14 days. 



Guernsey July 18 to 28 ... = 11 days.
