Freeze odds, by date
| Odds | Last spring freeze after | First fall freeze before |
|---|---|---|
| 9 years in 10 | Jan 1 | Feb 12 (next year) |
| Median — 1 year in 2 | Jan 26 | Jan 16 (next year) |
| 1 year in 10 | Feb 15 | Dec 27 |
The top row is the risky edge: in 9 years of 10 a spring freeze still comes after it, so tender transplants set out then need cover. The bottom row is the cautious date — only 1 year in 10 freezes after it — and the one to plan uncovered tender transplants against. Freeze-free season: 365 days median, at least 358 in 9 years of 10, no freeze at all in 1 year of 10. NOAA ranks season length year by year, so it is not the gap between two rows above.

How long is the growing season in Jupiter, FL?
NOAA counts a full 365-day freeze-free season at JUNO BEACH, FL in a typical year. What limits a sauce garden here is heat: peppers and tomatoes drop flowers in sustained hot nights, so plant to finish before peak summer or after it breaks.
What growing zone is Jupiter, FL?
USDA hardiness zone 10b, per the 2023 USDA Plant Hardiness Zone Map for ZIP 33458. A zone describes the coldest winter night, not when frost ends, so it is the wrong number for a planting calendar — the frost dates on this page are the right one.
When should I plant tomatoes in Jupiter, FL?
Start Roma VF (determinate paste) seeds indoors around Dec 15 and transplant around Feb 2, 1 week after the median last frost. To cut the freeze risk to one year in ten, wait for Feb 15. First ripe fruit lands around Apr 18.
