USDA Hardiness Zone 10B covers the southern tip of Florida, Hawaii, and the warmest coastal pockets of Southern California, with average annual minimum temperatures between 35°F and 40°F. The growing season extends to approximately 350 frost-free days, with a last spring frost around Jan 15 and first fall frost near Dec 31. Frost is rare and brief. Zone 10B gardeners can grow vegetables year-round, though the peak production window for most crops is the cooler October-through-April season.
