The spread between the 90% and 10% spring dates is 34 days, a measure of how variable spring is here.

Freeze probability table

Spring: chance the last freeze falls *after* the date. Fall: chance the first freeze falls *on or before* the date. Season: days between, exceeded in 90% / 50% / 10% of years.
Threshold	Last spring occurrence			First fall occurrence			Season length (days) 90% / 50% / 10%
Threshold	Early (90% chance of a later freeze)	Median (50%)	Cautious (10% chance of a later freeze)	Early (10% chance by then)	Median (50%)	Late (90% chance by then)	Season length (days) 90% / 50% / 10%
36°F (light frost possible)	Mar 21	Apr 6	Apr 23	Oct 17	Nov 1	Nov 13	186 / 207 / 229
32°F (freeze)	Mar 7	Mar 26	Apr 10	Oct 27	Nov 9	Nov 27	208 / 230 / 256
28°F (hard freeze)	Feb 15	Mar 12	Mar 30	Nov 5	Nov 23	Dec 16	231 / 257 / 291

Read the spring “Cautious” column as the safer planting date: only about 1 year in 10 has a freeze after it. NOAA computes these from daily minimum temperatures at the station; your yard can differ, especially in low spots or at a different elevation.

Fall estimates count back from the median first fall freeze (32°F for tender crops, 28°F hard freeze for cool-season crops) by the longer days-to-harvest figure. These are rough planning aids, not recommendations for any specific variety; check seed packets and your county extension office.
