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 8 | Mar 25 | Apr 8 | Oct 29 | Nov 10 | Nov 29 | 211 / 231 / 256 |
| 32°F (freeze) | Feb 18 | Mar 12 | Mar 30 | Nov 6 | Nov 24 | Dec 19 | 231 / 258 / 291 |
| 28°F (hard freeze) | Jan 25 | Feb 25 | Mar 19 | Nov 17 | Dec 10 | Jan 9 | 259 / 293 / 329 |
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.
