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) | Apr 6 | Apr 24 | May 11 | Oct 7 | Oct 20 | Nov 1 | 159 / 180 / 201 |
| 32°F (freeze) | Mar 24 | Apr 10 | May 1 | Oct 15 | Oct 29 | Nov 12 | 177 / 203 / 225 |
| 28°F (hard freeze) | Mar 8 | Mar 28 | Apr 14 | Oct 26 | Nov 8 | Nov 29 | 203 / 228 / 253 |
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.
