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 31 | Apr 13 | Apr 29 | Oct 14 | Oct 26 | Nov 6 | 177 / 196 / 215 |
| 32°F (freeze) | Mar 18 | Apr 1 | Apr 14 | Oct 22 | Nov 3 | Nov 17 | 198 / 216 / 237 |
| 28°F (hard freeze) | Mar 2 | Mar 21 | Apr 5 | Nov 1 | Nov 14 | Dec 2 | 217 / 238 / 264 |
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.
