Downtown Los Angeles woke up Saturday, February 21, 2026 to crystal-clear skies, a brisk 44°F, and a dusting of frost in some valley neighborhoods. A Freeze Warning and several Frost Advisories are in place through 9 AM PST for wind-sheltered inland pockets, but the chill will not last long. By afternoon, sunshine and a noticeable warm-up will start to flip the script on the morning cold.
Morning Frost And Freeze
Frost Advisories stretch across parts of the Ventura County valleys, the western San Fernando Valley, the Santa Clarita Valley, and interior sections of the Central Coast, while a Freeze Warning holds for the Cuyama Valley through 9 AM PST Saturday. Temperatures dipped to near or below freezing overnight in the most sheltered spots, putting exposed plants and uninsulated pipes at risk. Small Craft Advisory conditions are possible on some outer waters this afternoon into Saturday night, and the air mass is expected to quickly shift toward warmer, drier conditions later in the weekend, according to the National Weather Service Los Angeles/Oxnard.
Sun, Then A Quick Warm-Up
Sunshine takes over today with a high near 68°F in downtown, then temperatures climb into the mid 60s to mid 70s Sunday and push toward the low 80s by Monday for many inland neighborhoods. Most of the basin is expected to stay dry through midweek, with the best rain chances aimed well north of the region. If you have outdoor plans, the warm afternoons will be your prime window.
What To Watch And How To Prepare
Early commuters should budget a little extra time and watch for slick, shaded ramps where frost can hang on into mid morning, while gardeners will want to cover or bring in tender plants before dawn. Boaters and beachgoers should check local marine advisories before heading offshore and steer clear of exposed jetties during higher surf.
