Zone 10a Almanac

What growers in zone 10a actually recorded

Every row below comes from real plantings and harvest logs kept by growers in zone 10a. Nothing is published until enough growers have recorded it, so the gaps are real gaps, not guesses.

Last frost: January 30

First frost: December 25

These two frost dates are the conventional zone-wide averages for zone 10a, not a reading from a station near you, so treat them as plus or minus about two weeks until you enter your own. Crop rows below are medians of member records, each published only after enough growers logged it. See the full method, sources, and confidence bands.
