Lemoore, CA: when does the frost end?

Zone 9a

The last spring frost here typically falls around 02/24, about 180 days from today. Fall's first freeze usually shows up around 11/22, roughly 265 days after the last spring frost.

Zone 9a (20 to 25°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Lemoore, not a forecast for this year.

Stretching the season past the first frost

With roughly 12 weeks until Lemoore's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here
