Freeze odds, by date

OddsLast spring freeze afterFirst fall freeze before
9 years in 10Dec 17 (prior winter)Feb 9 (next year)
Median — 1 year in 2Jan 9Jan 3 (next year)
1 year in 10Feb 13Dec 11

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 341 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.
