Weather information for growing grapes

Hourly and daily weather data
MSU hosts Enviro-weather, an Internet resource with weather data for pest management and other plant production practices. Enviro-weather draws data from weather stations in many of Michigan's grape growing regions. Pick the station nearest you to get daily or hourly information such as air and soil temperatures, leaf wetness, precipitation, wind speed and growing degree day accumulations. There is also a model for predicting black rot development, and the model for Concord grape weight. The data from these stations help with decision making -- keep in mind the most accurate measurements are those taken at the site of your vineyard.
