Tampa frost dates and planting season
When to plant vegetables here. Cover calendars (fleece, cold frame, unheated greenhouse) are on each plant’s when-to-plant page.
Tampa is frost-free here (frost in fewer than about 1 winter in 10). Growing windows follow temperature limits, not frost dates. Plant cool-season crops after about November 2; warm-season crops can be planted any time of year here.

Frost and suitability dates are typical figures from climate statistics. Microclimates vary; they are not a guarantee.
Frost dates calculated by Plan & Plant from Weather data by Open-Meteo.com (CC BY 4.0). Local frost pockets, valleys and coastal sites can differ by 1–3 weeks.
How we calculated this
- Data: ERA5-Land via Open-Meteo, cell 27.95, -82.46, years 2019–2026 (not a 30-year climate normal yet).
- Typical and safer dates: Typical last frost is the date after which half of winters in this sample had no more frost; safer is later in the sample so fewer winters still frosted.
- Confidence: Provisional — short or thin sample for this place.
- Full methodology (algorithm 2026-10-season-6).

Warm season: suitable
A week is suitable for a crop type when its average low and high sit inside that type's range and its possible readings stay within the frost and heat limits (cool: 28 °F to 81 °F, warm: 32 °F to 90 °F); crossing a limit makes it tolerable, and for warm crops any chance of frost makes it too cold.
