Since the Swiss anemometer in St Moritz (which however 
indicated the greatest average amount of wind) was in a 
very sheltered position, the figures obtained by it cannot 
be directly compared with those of the neighbouring places. 
The number of miles of wind registered in 
November 1882, was 1965-33 
December 1422-74 
January 1883 1674-94 
F ebruary 1556-72 
March 274075 
April .....2181-05 
The following analysis will give an idea as to the 
frequency of strong wind, and by the side of the two 
months in St. Moritz I give a similar table for the month 
of January, 1882, in Davos. That month was among the 
stillest which has ever been known in the Alps. 
The “ night ” is from 3 p.m. of the previous day to 9 a.m., 
“ morning ” 9 a.m. to 1 p.m., “ afternoon ” 1 p.m. to 3 p.m. 
Average rate per hour.
