When is the last frost in Arizona?

It varies by location. Across Arizona, average last spring frost dates range from January 4 (Mohave Valley) to June 21 (Parks). 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 Arizona?: It varies by location. Across Arizona, average last spring frost dates range from January 4 (Mohave Valley) to June 21 (Parks). 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.
