When is the last frost in Maryland?

It varies by location. Across Maryland, average last spring frost dates range from March 23 (Gibson Island) to May 7 (Mc Henry). 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 Maryland?: It varies by location. Across Maryland, average last spring frost dates range from March 23 (Gibson Island) to May 7 (Mc Henry). 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.
