Miami, FL — USDA Zone 11a

Frost dates and growing season in Miami

Miami spans USDA zones 10 to 11 across its ZIP codes (Zone 10b, Zone 11a); the city center sits in Zone 11a, so warmer and cooler pockets exist either side of that.

These are 50%-probability averages modeled from Miami's USDA hardiness zone and regional climate normals — not a single-station reading. In a typical year the last spring frost will have passed by no frost, but a colder-than-average year can run 1-2 weeks later. Plant tender crops (tomatoes, peppers, basil) once both soil and night temperatures are consistently warm — a thermometer beats the calendar.

Growing season in Miami

Miami, Florida sits in USDA Zone 11a, with roughly 365 frost-free days between an average last spring frost around no frost and a first fall frost around no frost. That is a near year-round season — the limiting factor is summer heat, not frost, so schedule cool-season crops for winter and protect tender ones from extreme highs. Miami lies near 25.8°N; higher-latitude gardens get longer midsummer days but a tighter shoulder season at this zone.

Local microclimate notes

Zone tables give you the average — but Miamigardens vary. South-facing walls and paved areas can run a full half-zone warmer than the published rating. Low-lying spots, frost pockets, and shaded north sides can run colder. If you've gardened here a few seasons, your own frost record — the last time you actually got frost damage — beats any national average.

Source and methodology

Hardiness zone from the USDA Plant Hardiness Zone Map (2023 revision). Frost-date and growing-season figures are modeled from Miami's USDA hardiness zone and regional NOAA 1991-2020 climate normals — zone-level estimates, not a per-station record, so treat them as planning guidance and confirm against your own local frost history. Crop recommendations draw on US Cooperative Extension references, curated by the Growli editorial team. Last reviewed June 2026.
