Downtown Los Angeles is warming quickly on Sunday, March 22, 2026, after a cool, foggy start, with highs forecast near 83.6°F this afternoon. Coastal pockets will stay cooler under low clouds and occasional dense fog through the morning, while inland and valley neighborhoods climb into the upper 80s. Light south to southwest breezes are expected this afternoon ahead of a stronger warm-up later in the week.
Foggy Mornings, Sunny Afternoons
Low clouds and pockets of dense fog will be most likely along the immediate coast through Monday, cutting visibility near the waterfront and on coastal freeway ramps. For many neighborhoods, the marine layer should burn off by midmorning, giving way to mostly sunny skies and warm afternoons.
Midweek Warm Spell
Highs turn sharply warmer early this week, with temperatures expected to reach near 89.6°F on Monday, March 23, and around 90.6°F from Tuesday through Thursday (March 24 to 26). Forecasters also note that, if current trends hold, Downtown Los Angeles's average maximum temperature for March would be roughly 83.96°F, a mark that would exceed recent records. Mariners and boaters should plan for choppy seas, and the chance of Small Craft Advisory level winds across parts of the bight through midweek, according to the National Weather Service Los Angeles/Oxnard.
How To Stay Cool
Plan outdoor errands for the morning or evening, drink plenty of water, and avoid prolonged midday exertion. If you do not have reliable air conditioning, Los Angeles County lists cooling centers and guidance online and via 2-1-1. You can see the county map at Ready LA County. If you are boating, keep an eye on the horizon: fog and gusty offshore breezes can reduce visibility and make conditions choppy near the coast.
