Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | May 13 |
| 50% (the "average" last frost) | Jun 1 |
| 10% (cautious: only 1 year in 10 freezes later) | Jun 20 |

|---|---|
| 10% (early: 1 year in 10 freezes this soon) | Sep 1 |
| 50% (the "average" first frost) | Sep 16 |
| 90% (late: most years have frozen by now) | Sep 29 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Jun 19 | Sep 3 |
