Where this data comes from

These dates are computed from the nearest official weather station with long-term records: Deer, Ar, about 11 miles away@if(!empty($station['elevation_ft'])), at 2,375 ft elevation. The further the station and the greater the elevation difference from your yard, the more your local frost timing can vary.

How we calculate these dates

Frost and freeze dates come from the NOAA 1991–2020 U.S. Climate Normals, the National Oceanic and Atmospheric Administration's 30-year averages for each weather station. A date shown at the 50% level is the median: in half of years the frost falls on or before it. The 10% and 90% columns show the early and late ends of the range, so you can plant on the odds you're comfortable with. These are long-term averages, not a forecast for this year - always check your local outlook before planting.
