Frost risk in zone 7a
Zones are based on winter cold, not on frost dates, so the last spring frost varies a lot within a zone. Across zone 7a, the typical last frost ranges from about April 5 in the earliest tenth of ZIP codes to April 29 in the latest tenth, and the first fall frost from October 15 to November 2. For a typical place in the zone:
- April 1Risky: a later frost happens in 9 years out of 10
- April 16Typical: frost after this date in half of years
- May 3Safe: a later frost only 1 year in 10
Green Beans are killed by frost, so if you want to be safe, plant out after the safe date rather than the typical one, or be ready to cover plants on a cold night.
