Cathedral City, California planting calendar and frost dates

Frost dates in Cathedral City

A 32°F night is rare here: it happens in about 11% of years, so median frost dates do not describe a typical year.

NOAA U.S. Climate Normals 1991-2020 for Palm Springs Rgnl Airport, 2.3 miles E of the city center. Low-lying and rural spots often frost later in spring and earlier in fall than airports and city centers. Cathedral City shares this station with Palm Desert, so the two cities have the same frost dates and planting calendar.

What to plant each month in Cathedral City

The main garden season runs from September through March. Lettuce, brassicas, roots and onions grow through the cool, sunny winter, and frost is light and infrequent. Melons, squash, cucumbers, tomatoes and peppers are planted January-March so they produce before the intense heat of May. Summer highs above 110°F stop most vegetables except okra, and late-summer plantings of melons and squash are risky because whiteflies peak then. The months below follow the planting calendar for California Low Desert (Coachella and Imperial Valleys) from the Cooperative Extension sources listed.
