Downtown Los Angeles woke up to cool, muggy air on Sunday, July 19, 2026, with patchy fog draped along the coast that should thin out by late morning. Once the gray lifts, forecasters expect mostly sunny skies this afternoon and a high near 84°F, while inland neighborhoods turn even warmer heading into mid‑week.
Morning Gloom, Afternoon Heat
Patchy fog and low clouds are likely before 11 a.m. along beaches and in coastal valleys, cutting visibility on shoreline streets and nearby ramps. By midafternoon, temperatures should climb into the low to mid 80s, with light south‑southwest breezes around 0–10 mph. It is a classic layers day: cool and damp when you step out the door, noticeably warmer by lunch.
Dangerous Surf And Sneaky Rip Currents
The National Weather Service has a High Surf Advisory in effect from 5 p.m. Sunday, July 19 through 11 p.m. Tuesday, July 21, along with a Beach Hazards Statement for south‑facing shores through Tuesday evening. Southerly swells could make harbors and jetties especially dangerous. For the latest watches and beach‑by‑beach guidance, check the National Weather Service Los Angeles/Oxnard, and listen to local lifeguards. The Los Angeles County Lifeguards recommend steering clear of jetties and staying out of the surf when advisories are posted.
Gusty Winds, Choppy Seas And A Midweek Warm‑Up
Forecasters say afternoon wind gusts of 25–40 mph are possible in the Antelope Valley and nearby foothills, with isolated higher gusts up to about 45 mph in terrain‑enhanced spots like Lake Palmdale. Sundowner gusts may also strengthen in southern Santa Barbara County by Tuesday evening. Boaters are urged to check the marine forecast before heading out, since seas and winds are expected to rise later this week, and authorities warn that a midweek warm‑up could push highs into the mid to upper 80s, with a moderate chance that Heat Advisories will be needed by Wednesday, July 22. This continues a warming trend first flagged in our July 5 forecast.
