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 25 | Apr 8 | Apr 22 | Oct 17 | Oct 30 | Nov 11 | 187 / 206 / 224 |
| 32°F (freeze) | Mar 12 | Mar 29 | Apr 11 | Oct 27 | Nov 8 | Nov 26 | 206 / 226 / 249 |
| 28°F (hard freeze) | Feb 26 | Mar 16 | Apr 1 | Nov 4 | Nov 20 | Dec 8 | 227 / 249 / 279 |
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.
