Indiana frost dates
| 32°F freeze | 9 in 10 years | 1 in 2 years | 1 in 10 years |

| First fall freeze comes before | Oct. 27 | Oct. 13 | Oct. 1 |
Hard freeze (28°F): the median last one in spring is April 27 and the median first one in fall is Oct. 25. The growing season between the median 32°F freezes, May 8 to Oct. 13, runs about 157 days.
Planting tender plants after May 24 means a freeze afterward in only about 1 year in 10. Planting on May 8 leaves even odds. For lawn seeding windows, see our Pennsylvania grass seed guide.

Planning outdoor work in Indiana
Average lows sit at or below freezing from November through March, so plan base work, planting and seeding around the frost dates above. Frost depth and ground snow load for footings and roofs are set by your town; our design criteria by ZIP tool shows who sets them for your address. For planting beds, start with a soil test.

About this data
Station: NOAA’s Indiana 3 SE station (GHCN USC00364214), about 3 miles southeast of Indiana, elevation 1,102 ft, 40.597° N, 79.119° W. These are NOAA’s 1991–2020 U.S. Climate Normals, 30-year averages that NOAA recomputes every 10 years. NOAA rates this station’s precipitation normals standard, its snow normals provisional and its temperature and freeze normals standard. Standard means at least 24 years of data, with missing months filled from nearby stations. Provisional means at least 10 years of data, with gaps NOAA could not fill from nearby stations.
Your yard can differ from the station. Elevation, valleys and hillsides change how much snow falls and when the first and last freezes come.
