The map below shows the average date of the first frost in New York State. These dates are guides, and no guarantee that frost will not occur before the first date shown.
Microclimates have an effect on frost dates. Some valleys and low-lying areas can be plagued by early frosts well before the first frost date on cold nights when there is radiational cooling. Large bodies of water may moderate air temperatures at some sites, reducing the chances of frost.
