Temperatures of 32 F, or less, have been recorded as late as May 17th in the Spring, and as early as September 24th in the Fall. Figure 1 shows the monthly temperature means and extremes. The heaviest amounts normally occur during the Summer growing season. Snowfall averages about 26 inches a season, but on occasion has been more than twice that amount. At other times.
Destructive storms are infrequent in the vicinity of Freehold.
Summer thunderstorms occasionally combine high winds with heavy rainfall, and heavy rains have occurred in connection with hurricanes which move northward along the mid-Atlantic coast. A considerable portion of our Summer and Autumn rainfall comes from tropical storms which pass near the New Jersey coast. The average number of heating degree days per year is 5,235. In the Colts Neck area, periods of very hot weather lasting as long as a week are associated with a west-southwest flow of air, which has a long trajectory overland on the left of the Bermuda high pressure system. Extremes of cold are related to rapidly moving outbreaks of cold air which travel southeastward from Canada's Hudson Bay region.
