Growing Degree Days (GDD) Calculator – Growing Degree Days is commonly used by the fruit growers to estimate the ripening time of their crops. To calculate GDDs,
First, record the mean temperature; this can be done by adding together the high and low temperature for the day and dividing that value by two. If the mean temperature is at or below the base temperature for a crop or pest of interest, then the GDD value is zero. If the mean temperature is above the base temperature, then the GDD equals the value of the mean temperature minus the base temperature. If the low temperature of the day is below your crop or pests’ base value, use the base temperature during your calculations. The difference then sum up over a period of time then the sum will be the GDD in your area.
