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 18 | Apr 4 | Apr 19 | Oct 22 | Nov 3 | Nov 18 | 194 / 214 / 237 |
| 32°F (freeze) | Feb 28 | Mar 22 | Apr 6 | Oct 31 | Nov 12 | Dec 2 | 214 / 237 / 264 |
| 28°F (hard freeze) | Feb 6 | Mar 6 | Mar 27 | Nov 8 | Nov 26 | Dec 24 | 237 / 265 / 298 |
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.
