THE CLIMATE OF CALVERT COUNTY 



The prevailing character of the weather is indicated by Table XVII. 

 The average number of clear da3^s is greatest during August, September, 

 and October, and least during early spring. The annual number of 

 cloudy days is 166; this is somewhat high, and it is thought to include 

 many days on which rain fell, but which under stricter application of the 

 rules for determining the character of the day would have been recorded 

 partly cloudy. The average number of days with fog is 9, with sleet 

 and hail 6.
