The map above shows the average freeze free period between the last frost in spring and the first frost in fall. Use it to help decide which varieties or cultivars of plants to grow.

Keep in mind that the dates are guides, and no guarantee that your frost free period will always fall in the range indicated by the map.

Also remember that microclimates have a tremendous effect on frost. Some valleys and low-lying areas can be plagued by late frosts and early frosts on cold nights when there is radiational cooling. Large bodies of water may moderate air temperatures at some sites, reducing the chances of frost.

Contact your county's Cornell Cooperative Extension staff for local advice on the length of your growing season, frost and microclimates.

National frost and frost-free season maps are available from the NOAA National Climatic Data Center.
