Last frost and first frost are averages (a 50% chance of frost later in spring or earlier in fall). Safer date is the spring date with only a 10% chance of a later frost. * The first frost usually comes after the new year.

Using these dates

Plant hardy crops like peas and spinach several weeks before your last frost, and tender crops like tomatoes and peppers after it, once nights stay above 50°F. The Seed Starting Calculator turns your frost date into sowing and planting dates, and When to Plant Tomatoes explains the timing in detail.

Data: NOAA National Centers for Environmental Information, U.S. Climate Normals 1991–2020, 32°F threshold.
