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 9 | Apr 22 | Oct 18 | Oct 31 | Nov 11 | 187 / 204 / 223 |
| 32°F (freeze) | Mar 13 | Mar 31 | Apr 15 | Oct 27 | Nov 8 | Nov 25 | 205 / 224 / 248 |
| 28°F (hard freeze) | Feb 25 | Mar 18 | Apr 3 | Nov 5 | Nov 21 | Dec 13 | 224 / 250 / 281 |
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.
