Frost risk in zone 8b

Zones are based on winter cold, not on frost dates, so the last spring frost varies a lot within a zone. Across zone 8b, the typical last frost ranges from about March 5 in the earliest tenth of ZIP codes to April 3 in the latest tenth, and the first fall frost from November 2 to November 24. For a typical place in the zone:

  • February 25Risky: a later frost happens in 9 years out of 10
  • March 17Typical: frost after this date in half of years
  • April 6Safe: a later frost only 1 year in 10

Basil 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.
