Downtown Los Angeles is rolling out of bed under patchy fog and muggy low-60s this Monday morning, with the marine layer expected to burn off by mid-morning. Once it clears, look for mostly sunny skies and a high near 79°F.
Heat Advisory Midweek
A Heat Advisory will blanket much of the inland coastal plain from 8 a.m. Tuesday through 9 p.m. Thursday, and forecasters say the warmest readings should land on Wednesday. Inland neighborhoods and interior valleys are expected to climb into the low-to-mid 80s, with a few spots pushing into the mid-80s on the hottest day. The advisory highlights an elevated risk of heat illness for the very young, older adults, people without air conditioning, and outdoor workers, according to the National Weather Service Los Angeles/Oxnard.
Foggy Mornings, Sunny Afternoons
Along the coast and through coastal canyons, patchy fog should linger until about 11 a.m., then give way to mostly sunny skies by lunchtime. Afternoon breezes will be light out of the south-southwest, generally 0–10 mph with gusts near 10 mph inland, and the added humidity will make the afternoons feel a bit stickier than usual. If you are planning outdoor time, try to aim for early morning or evening.
Where To Cool Off
City and county facilities often open as cooling centers during heat events; you can call 2-1-1 for the nearest spot or use the county's searchable map of centers. Downtown's Central Library (630 W. 5th St.) is a regular air-conditioned refuge in the area. For county guidance and a map of cooling locations, see Ready LA County.
What To Expect Later This Week
Wednesday currently looks like the peak of the heat, after which temperatures should ease a bit heading into Friday and the weekend as onshore flow strengthens. The marine layer is expected to thicken late in the week, which should bring cooler overnight lows in the low-60s and more comfortable afternoons by the weekend.
