USDA zone 10b planting guide
Zone 10b means an average annual winter low of 35°F to 40°F. That coldest-temperature band describes winter cold tolerance. Frost dates and growing-season length come separately from NOAA climate normals.
A typical location in zone 10b sees its last spring frost around January 16 and its first fall frost around January 15. Pick a crop for its zone 10b planting dates, or get dates for your exact ZIP.
This near-frost-free pattern wraps across New Year. The listed first fall frost falls in the following calendar year.
