Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Apr 23 |
| 50% (the "average" last frost) | May 9 |
| 10% (cautious: only 1 year in 10 freezes later) | Jun 2 |
Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

| 50% (the "average" first frost) | Oct 17 |
| 90% (late: most years have frozen by now) | Nov 3 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|

| 32°F (freeze) | May 9 | Oct 17 |
| 28°F (hard freeze) | Apr 24 | Oct 31 |
