What are Growing Degree Days?

Growing Degree Days (GDD) measure accumulated heat above a base temperature — not calendar days.

GDD = max(0, (Tmax + Tmin) / 2 − 10)

Each day contributes a value equal to how many degrees the average temperature exceeds 10 °C. A day with a high of 26 °C and a low of 12 °C contributes (26 + 12) / 2 − 10 = 9 GDD.

The total GDD for a year is the sum of all daily values. A warm summer can easily produce 1 000 – 1 500 GDD, which is why the total is much larger than 365.

Base temperature: 10 °C (growing threshold for most plants in temperate climates).
