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 17 | Mar 31 | Apr 14 | Oct 24 | Nov 6 | Nov 20 | 201 / 222 / 246 |
| 32°F (freeze) | Feb 28 | Mar 20 | Apr 4 | Nov 3 | Nov 17 | Dec 6 | 220 / 243 / 272 |
| 28°F (hard freeze) | Feb 5 | Mar 7 | Mar 26 | Nov 12 | Dec 1 | Jan 1 | 241 / 273 / 307 |
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.
