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 15 | Apr 3 | Apr 18 | Oct 22 | Nov 2 | Nov 18 | 195 / 215 / 239 |
| 32°F (freeze) | Feb 27 | Mar 18 | Apr 6 | Oct 31 | Nov 14 | Dec 3 | 216 / 239 / 268 |
| 28°F (hard freeze) | Feb 4 | Mar 4 | Mar 24 | Nov 8 | Nov 29 | Dec 29 | 242 / 269 / 304 |
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.
