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) | Feb 26 | Mar 19 | Apr 6 | Nov 1 | Nov 16 | Dec 4 | 218 / 242 / 270 |
| 32°F (freeze) | Feb 4 | Mar 2 | Mar 25 | Nov 11 | Nov 30 | Dec 28 | 243 / 270 / 304 |
| 28°F (hard freeze) | Jan 15 | Feb 13 | Mar 13 | Nov 24 | Dec 22 | Jan 17 | 267 / 304 / 339 |
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.
