Zone 9b means an average annual winter low of 25°F to 30°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 9b sees its last spring frost around February 1 and its first fall frost around December 9. Pick a crop for its zone 9b planting dates, or get dates for your exact ZIP.
