Downtown Los Angeles woke up Tuesday, July 28, 2026, under a blanket of patchy morning fog that should thin by late morning, giving way to mostly sunny skies and a high near 88°F. A south breeze around 5 to 10 mph should keep it feeling a bit less toasty than the inland valleys, with overnight lows slipping into the upper 60s. Those nights, however, are expected to turn stickier as the week rolls on.
Heat Builds Later This Week
After a brief cooldown through Thursday, a strong upper ridge is expected to crank the temperatures back up from Friday, July 31, through Sunday, August 2, 2026. Forecasts call for widespread highs of 95 to 105°F away from the immediate coast and pockets of 105 to 115°F in the hottest valleys and interior spots. Overnight lows are expected to sit in the 70s for many neighborhoods, which raises the risk of heat-related illness for anyone without dependable air conditioning. Heat advisories and warnings are likely across much of the region, according to the National Weather Service Los Angeles/Oxnard.
Morning Fog, Afternoon Sun
On Tuesday, patchy fog should burn off before 11 a.m., leaving Downtown mostly sunny through the afternoon with a high near 88°F, a relatively comfortable setup compared with the scorching conditions expected inland.

Dangerous Surf and Rip Currents
A large southerly swell from Hurricane Genevieve is set to drive higher surf into south-facing beaches beginning Wednesday evening and likely into the weekend. That will mean a spike in rip-current danger and hazardous shoreline conditions. Beachgoers and small-boat operators are urged to obey lifeguards, steer clear of jetties and be ready for choppy seas and intermittent Small Craft Advisory conditions offshore, according to the National Weather Service Los Angeles/Oxnard.
What To Do
Shift strenuous outdoor work to the early morning or late evening, drink plenty of water and check in on neighbors who may not have access to cooling. If you need help locating a cooling center, call 2-1-1 or consult Los Angeles County resources. If you are heading to the beach, stick to staffed areas, follow posted advisories and give rip-prone zones a wide berth until the surf and currents settle down.
