Search your town, ZIP or address above. The tool finds the nearest NOAA weather station and shows the date its last spring frost (32°F) has passed in half of years, plus the later date it has passed in 9 years out of 10.
From NOAA’s 1991-2020 U.S. Climate Normals, the official 30-year averages for more than 7,000 weather stations. NOAA publishes each station’s spring and fall freeze dates at several probability levels; the tool shows the closest station and how far away it is.
Not for frost-tender crops. On the average date, about half of years still have a frost after it. The safer planting date is the one a frost comes after only 1 year in 10, and the tool shows it next to the average.
Yes. Higher ground usually has a shorter season, with later spring frosts and earlier fall ones, and low spots where cold air settles can frost when the station does not. The tool tells you when the station is far away; the land report adds the height of your exact point.
Yes. It is free, needs no account, and the frost data is public NOAA data.
