Oklahoma has 193 NOAA weather stations with freeze records in the 1991–2020 climate normals. The typical last spring frost ranges from March 15 at Ardmore to April 26 at Boise City 2 E; at half the stations it has come by April 5. The first fall frost typically arrives between October 17 at Boise City 2 E and November 15 at Hugo, with a median of November 1.

The growing season between the typical frosts runs from 173 days at Boise City 2 E to 244 days at Hugo; 209 days at the median station.

Typical dates have a 50% chance of a frost after them in spring, and before them in fall; safer dates, 10%. A garden can differ from its nearest station, especially in a valley or on a hillside: see why your garden may differ.

Questions

When is the last frost in Oklahoma?

It depends on where you are. The typical last spring frost at Oklahoma's NOAA stations ranges from March 15 to April 26, and half of them have had it by April 5. Enter your ZIP code above for the station nearest you.

When is the first frost in Oklahoma?

Typically between October 17 and November 15, depending on the station; the median is November 1. Plan fall crops back from your own station's date.

What do "typical" and "safer" mean?

With the typical (50%) last-frost date, half of years still have a frost after it. With the safer (10%) date, only one year in ten does. In fall it's the other way around: the safer date is the earlier one.
