First frost expected October 21 across Oklahoma

Seasonal Change on the Horizon

While Oklahomans still face hot days heading into October, forecasters say the first frost of the season could arrive by October 21. That estimate comes from decades of statewide weather data.

What the Data Shows

Climatologists note that Oklahoma typically experiences its first frost in mid-to-late October. While the next 10 days bring a return of summerlike heat, forecasters expect temperatures to trend downward by mid-month. The average high will fall to about 73 degrees.

Preparing for the First Frost Cold Snap

Gardeners and farmers are encouraged to prepare their crops, and residents may want to cover sensitive plants or bring them inside. The first frost marks a seasonal turning point, often arriving just before the first freeze.
