  Graph of Thaw Degree-days Graph of Rainfall     Graph of Growing Season
*Thaw degree-days is a method of estimating the season's overall warmth. It is calculated by taking the average daily temperature, subtracting a baseline temperature (ours is 32F), then adding all the numbers from May 1 through Sept 30. The higher the number, the warmer the season.
