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 12 | Mar 6 | Mar 27 | Nov 7 | Nov 29 | Dec 25 | 239 / 268 / 298 |
| 32°F (freeze) | Jan 25 | Feb 20 | Mar 16 | Nov 23 | Dec 19 | Jan 15 | 266 / 298 / 332 |
| 28°F (hard freeze) | Jan 2 | Feb 3 | Mar 3 | Dec 6 | Jan 3 | Feb 4 | 294 / 329 / 365 |
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.
