The spread between the 90% and 10% spring dates is 38 days, a measure of how variable spring is here.
Freeze probability table
| Threshold | Last spring occurrence | First fall occurrence | Season length (days) 90% / 50% / 10% | ||||
|---|---|---|---|---|---|---|---|
| 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) | ||
| 36°F (light frost possible) | Mar 21 | Apr 7 | Apr 22 | Oct 17 | Oct 29 | Nov 12 | 185 / 205 / 225 |
| 32°F (freeze) | Mar 5 | Mar 25 | Apr 12 | Oct 26 | Nov 9 | Nov 27 | 205 / 228 / 253 |
| 28°F (hard freeze) | Feb 18 | Mar 12 | Mar 31 | Nov 4 | Nov 22 | Dec 14 | 229 / 256 / 287 |
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.
