Farm Weather Map and Growing Degree Day Calculator
Growing Degree Days (GDD) are a measure of heat accumulation based on daily air temperature. In this tool, the GDD is calculated using the basic method, which calculates the daily mean temperature by adding together the max and min temperatures and dividing by two. Using the required base temperature, the base temperature is subtracted from the mean temperature to give you the accumulated GDD.
The web based tool has been designed and tested using the Nova Scotia Farm Weather Station Network and reviewed by Perennia’s Agri-Techology Specialist. It was developed in concert with Cape Breton Mesonet and builds off their useful weather map by incorporating a tool to calculate growing degree days. You have access to the weather data from over 100 on-farm weather stations in Nova Scotia!
