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 3 | Mar 25 | Apr 10 | Oct 31 | Nov 13 | Dec 2 | 212 / 236 / 261 |
| 32°F (freeze) | Feb 14 | Mar 10 | Mar 29 | Nov 7 | Nov 26 | Dec 22 | 236 / 265 / 296 |
| 28°F (hard freeze) | Jan 21 | Feb 22 | Mar 17 | Nov 21 | Dec 13 | Jan 13 | 261 / 296 / 330 |
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.
