Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Dec 11 (prior Dec) |
| 50% (the "average" last frost) | Dec 29 (prior Dec) |
| 10% (cautious: only 1 year in 10 freezes later) | Jan 13 |
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) | Dec 11 |
| 50% (the "average" first frost) | Dec 26 |
| 90% (late: most years have frozen by now) | Jan 13 (next year) |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Jan 8 | Dec 24 |
| 32°F (freeze) | Dec 29 (prior Dec) | Dec 26 |
| 28°F (hard freeze) | n/a | n/a |
n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
Vegetable planting calendar for 94005
Dates count from your average last spring frost (Dec 29) and first fall frost (Dec 26). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
