Freeze odds, by date
| Odds | Last spring freeze after | First fall freeze before |
|---|---|---|
| 9 years in 10 | Dec 2 (prior winter) | Feb 13 (next year) |
| Median — 1 year in 2 | Dec 30 (prior winter) | Dec 25 |
| 1 year in 10 | Mar 13 | Nov 26 |
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 336 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.
