Temecula, California planting calendar and frost dates

Frost dates in Temecula

A 32°F night is rare here: it happens in about 17% of years, so median frost dates do not describe a typical year.

NOAA U.S. Climate Normals 1991-2020 for Fallbrook 5 Ne, 4.5 miles SSW of the city center and 129 feet higher. Low-lying and rural spots often frost later in spring and earlier in fall than airports and city centers.

What to plant each month in Temecula

Cool-season crops are planted from late summer through winter, but the window is shorter than on the coast because summers are too hot for lettuce, peas and cole crops and occasional winter frosts can nip tender growth. Warm-season crops go in from April, after frost danger, through June; hot, dry summers ripen tomatoes, melons and peppers well but heat above the mid-90s can stop fruit set in July and August. Rain comes almost entirely November to March. The months below follow the planting calendar for Southern California Inland Valleys from the Cooperative Extension sources listed.
