Climate & Weather




USDA Hardiness Zone map for New York – Helps you determine which herbaceous perennials and woody trees, shrubs and vines will survive winters where you garden.

Average last spring frost date – Remember that average means that there’s a good chance there will be frost after these dates. (You should wait until your soil has warmed up before planting frost-sensitive crops anyway.)

Average first fall frost date – Local microclimates may extend or hasten the end of your growing season for frost-sensitive crops.

Average freeze-free season – This is the window you have to grow frost-sensitive crops.



Microclimates – Terrain, lakes, and buildings can affect your hardiness zones and frost dates.



NEWA – Cornell’s Network for Environment and Weather Applications provides great information on growing degree days, historical weather data, pest and crop forecasts, and more.

Northeast Regional Climate Center in the Department of Earth and Atmospheric Sciences facilitates and enhances the collection, dissemination and use of climate data and information, as well as monitors and assesses climatic conditions and impacts in the twelve-state, northeastern region of the United States.
