Freeze odds, by date
| Odds | Last spring freeze after | First fall freeze before |
|---|---|---|
| 9 years in 10 | Mar 29 | Nov 8 |
| Median — 1 year in 2 | Apr 13 | Oct 27 |
| 1 year in 10 | Apr 29 | Oct 14 |
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: 195 days median, at least 176 in 9 years of 10, at least 217 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 Apr 2 and first of Nov 5.
