    Frost dates

    When is the first frost? US cities, earliest first

    A frost date here is the first or last night of the cold season when a city’s official weather station reads 32°F or colder, from NOAA’s 1991 to 2020 normals. Here are all 129 US cities we track.

    Some cities get frost in September. Some only ever see it on a cold glass.
