Freeze odds, by date
| Odds | Last spring freeze after | First fall freeze before |
|---|---|---|
| 9 years in 10 | Jan 31 | Dec 26 |
| Median — 1 year in 2 | Feb 27 | Nov 30 |
| 1 year in 10 | Mar 18 | Nov 10 |
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: 278 days median, at least 247 in 9 years of 10, at least 315 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 Feb 7 and first of Dec 18.
