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 27 | Mar 18 | Apr 3 | Nov 12 | Nov 29 | Dec 19 | 234 / 257 / 285 |
| 32°F (freeze) | Feb 9 | Mar 3 | Mar 21 | Nov 25 | Dec 13 | Jan 9 | 257 / 286 / 314 |
| 28°F (hard freeze) | Jan 19 | Feb 17 | Mar 10 | Dec 7 | Dec 31 | Jan 23 | 284 / 312 / 345 |
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.
