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 13 | Mar 29 | Apr 10 | Oct 31 | Nov 12 | Nov 28 | 210 / 227 / 251 |
| 32°F (freeze) | Feb 27 | Mar 18 | Mar 31 | Nov 8 | Nov 25 | Dec 13 | 229 / 253 / 278 |
| 28°F (hard freeze) | Feb 8 | Mar 5 | Mar 21 | Nov 19 | Dec 8 | Jan 5 | 252 / 280 / 310 |
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.
