Sunday started thick and sticky in downtown Los Angeles, with mostly cloudy skies and temperatures hovering near 67°F. By this afternoon, those numbers are expected to jump into the upper 80s. The National Weather Service has issued a Heat Advisory from 10 a.m. Sunday, July 12, 2026, through 10 a.m. Tuesday, July 14, 2026, with an Extreme Heat Watch lined up from Tuesday morning, July 14, 2026, through Thursday evening, July 16, 2026. Warmer, more humid nights are on tap, which means a heightened risk of heat-related illness for anyone without dependable air conditioning through the week.
Today's Outlook
For Sunday, forecasters are calling for partly sunny skies and a sticky feel, with just a slight chance of rain showers between about 11 a.m. and 5 p.m. The high should land near 87°F, with light south-southwest winds around 0 to 10 mph. Monsoonal moisture will keep the air feeling muggy and could spark a few isolated downpours or brief thunderstorms, mainly inland and over the mountains. According to the National Weather Service Los Angeles/Oxnard, the best odds for measurable rain and any lightning are over the higher terrain, while coastal neighborhoods stay mostly dry, hazy and humid.
Midweek Heat Risk
Things heat up in a hurry starting Tuesday. Highs are expected to reach around 94°F on Tuesday and close to 95°F on Wednesday, with inland locations likely pushing into the 90s to low 100s. The Extreme Heat Watch in place from Tuesday through Thursday signals a real concern for dangerous conditions, particularly for outdoor workers, older adults and anyone who does not have air conditioning. Officials advise shifting heavy chores or workouts to early morning or evening hours and bracing for warm, stuffy nights, as humidity keeps overnight lows stuck in the upper 60s and 70s in some spots.
Beaches, Tides And Storm Chances
Along the coast, a Beach Hazard Statement is posted through Wednesday, and higher evening tides on Monday night are expected to peak around 7.1 to 7.7 feet above MLLW. That setup brings a small chance of minor coastal flooding, layered on top of a south-to-southwest swell. Beaches will run cooler than inland areas, but surf and rip current risk will be elevated, and those late-evening high tides may nudge water onto low-lying shorelines. Thunderstorm chances stay low and spotty during the afternoons, yet any storms that bubble up over the ocean or drift ashore could produce isolated and dangerous lightning.
Where To Cool Off
Los Angeles County maintains an interactive map of cooling centers and other relief sites, and officials recommend calling 2-1-1 for the latest locations and hours. The county also suggests using libraries, malls or community pools as backup cool zones and planning transportation to a cooler place if you do not have air conditioning at home.

Heat Safety Tips
Health experts are urging residents to drink plenty of water, skip alcohol during the hottest parts of the day and take frequent breaks if work or exercise has to happen outside. Try to schedule the heaviest tasks before 10 a.m. or after 6 p.m. Never leave children or pets alone in a vehicle, even for a short errand, and check on elderly neighbors or anyone with medical conditions that can worsen in the heat. Watch for signs of heat stroke, including confusion, fainting or a body temperature above 103°F. If those symptoms appear, call 911 right away.
