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 26 | Apr 10 | Apr 24 | Oct 17 | Oct 28 | Nov 10 | 185 / 203 / 222 |
| 32°F (freeze) | Mar 11 | Mar 29 | Apr 13 | Oct 26 | Nov 8 | Nov 23 | 206 / 227 / 248 |
| 28°F (hard freeze) | Feb 21 | Mar 15 | Apr 1 | Nov 6 | Nov 21 | Dec 11 | 228 / 253 / 281 |
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.
