Climate Prediction Center Weekly Corn Growing Degree Days

A corn growing degree day (GDD) is an index used to express crop maturity. The index is computed by subtracting a base temperature of 50?F from the average of the maximum and minimum temperatures for the day. Minimum temperatures less than 50?F are set to 50, and maximum temperatures greater than 86?F are set to 86.

These substitutions indicate that no appreciable growth is detected with temperatures lower than 50 or greater than 86. This data is provided weekly from March 1 to November 2 of the current year.
