Customized Growing Degree Day Calculations and Forecasting

This document provides step by step instructions for calculating growing degree day status and viewing growing degree day forecasts available from the uspest.org website. The uspest.org website allows users to select a weather station near them and then set their own degree units, lower and upper thresholds for growing degree calculations. Most pre-calculated growing degree reports use a default of 50F as their lower threshold. Unfortunately, this is not accurate for many of the crops we grow in Oregon. Thus, the ability to custom calculate and generate forecasts for growing degree days is ideal. Check out uspest.org, follow these instructions and get ahead on your planning!
