Freeze odds, by date
| Odds | Last spring freeze after | First fall freeze before |
|---|---|---|
| 9 years in 10 | Jan 2 | Jan 1 (next year) |
| Median — 1 year in 2 | Feb 1 | Dec 11 |
| 1 year in 10 | Feb 27 | Nov 23 |
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: 315 days median, at least 281 in 9 years of 10, at least 347 days in 1 year of 10. NOAA ranks season length year by year, so it is not the gap between two rows above. A hard freeze (28 °F) has a median last date of Jan 8 and first of Dec 26.
