When can you plant in Point Arena, CA?

Zone 10a

The last spring frost here typically falls around 02/25, about 181 days from today. The first fall frost typically arrives around 12/03, about 279 frost-free days later.

The USDA Plant Hardiness Zone Map puts Point Arena in Zone 10a (30 to 35°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 14 weeks of growing season left in Point Arena before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 02/25 isn't a guarantee

02/25 is the middle of 30 years of NOAA records, not a promise. Plant by 01/18 and you're betting against frost in roughly 9 years out of 10. 04/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
