Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Mar 20 |
| 50% (the "average" last frost) | Apr 4 |
| 10% (cautious: only 1 year in 10 freezes later) | Apr 22 |
Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.
First fall frost odds
| Chance the first 32°F freeze has happened by this date | Date |
|---|---|
| 10% (early: 1 year in 10 freezes this soon) | Oct 15 |
| 50% (the "average" first frost) | Oct 31 |
| 90% (late: most years have frozen by now) | Nov 20 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Apr 27 | Oct 16 |
| 32°F (freeze) | Apr 4 | Oct 31 |
| 28°F (hard freeze) | Mar 16 | Nov 18 |
n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
