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 10 | Mar 29 | Apr 16 | Oct 28 | Nov 7 | Nov 25 | 204 / 226 / 252 |
| 32°F (freeze) | Feb 23 | Mar 15 | Apr 4 | Nov 4 | Nov 20 | Dec 10 | 226 / 252 / 281 |
| 28°F (hard freeze) | Feb 1 | Feb 28 | Mar 20 | Nov 14 | Dec 5 | Jan 3 | 252 / 281 / 314 |
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.
