Lakeport, CA 95453 Frost Dates

When can you plant in Lakeport, CA?

Zone 8b

Around 03/05 is the usual last spring frost, about 189 days away. The first fall frost typically arrives around 11/21, about 259 frost-free days later.

Lakeport sits in USDA Zone 8b (15 to 20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 12 weeks of growing season left in Lakeport before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/05 isn't a guarantee

03/05 is the middle of 30 years of NOAA records, not a promise. Plant by 01/29 and you're betting against frost in roughly 9 years out of 10. 04/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
