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 30 | Apr 13 | Apr 30 | Oct 13 | Oct 26 | Nov 8 | 174 / 194 / 215 |
| 32°F (freeze) | Mar 14 | Apr 2 | Apr 19 | Oct 21 | Nov 4 | Nov 21 | 193 / 215 / 239 |
| 28°F (hard freeze) | Feb 28 | Mar 20 | Apr 6 | Oct 30 | Nov 14 | Dec 4 | 214 / 239 / 267 |
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.
