Find Average Annual Chill Hours at Your Location

Some plant species, such as fruit and nut trees, require a minimum number of chill hours per year to do well. It's important to know the average chill hours for your area when deciding which types and varieties to plant. The local chill hour calculator below will help you determine the chill hours at your location.

To determine the chill hours for your location, first find your location on the Weather Underground "Wundermap" linked below. Click the bubble of the closest station and write down the Station ID shown at the top (for example, KCALAKES1).

Go to Wundermap

In the Chill Hour Calculator linked below, enter the Station ID, start and end dates. These will default to the dates typically used for chill hour calculations in your area. Click "Calculate Chill". *** Note that it sometimes runs quickly and sometimes takes a very long time to run. The white bar under the button shows the progress with a gray line.
