Frost risk in zone 8a
Zones are based on winter cold, not on frost dates, so the last spring frost varies a lot within a zone. Across zone 8a, the typical last frost ranges from about March 18 in the earliest tenth of ZIP codes to April 7 in the latest tenth, and the first fall frost from October 31 to November 16. For a typical place in the zone:
- March 9Risky: a later frost happens in 9 years out of 10
- March 29Typical: frost after this date in half of years
- April 14Safe: a later frost only 1 year in 10
Cucumbers 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.
