When is the last frost in Washington?

It varies by location. Across Washington, average last spring frost dates range from February 26 (Blakely Island) to June 8 (Asotin). Look up your ZIP code for your local date.

Why do nearby towns have different frost dates?

Elevation, distance from large bodies of water, and whether a weather station sits in a valley, on a hill, or in a city all change how cold nights get. Each ZIP code is matched to the most representative nearby NOAA station.

Frequently asked questions

When is the last frost in Washington?: It varies by location. Across Washington, average last spring frost dates range from February 26 (Blakely Island) to June 8 (Asotin). Look up your ZIP code for your local date.
Why do nearby towns have different frost dates?: Elevation, distance from large bodies of water, and whether a weather station sits in a valley, on a hill, or in a city all change how cold nights get. Each ZIP code is matched to the most representative nearby NOAA station.
