Freeze odds, by date

OddsLast spring freeze afterFirst fall freeze before
9 years in 10Dec 14 (prior winter)Jan 16 (next year)
Median — 1 year in 2Jan 6Dec 20
1 year in 10Jan 31Dec 3

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: 351 days median, at least 325 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. A hard freeze (28 °F) has a median last date of Dec 30 (prior winter) and first of Dec 24.
