Downtown Los Angeles rolled into Saturday, July 11, under a gray blanket of patchy morning fog and mid 60s temperatures, with the cool start expected to flip into a warm afternoon near 85°F. The marine layer should peel back inland by late morning, while spots right on the shoreline may hang on to low clouds and cooler air. Heat is on track to build through the weekend and into next week as a bit of monsoonal moisture sneaks in, bringing a small late week shot at storms.
Foggy Mornings, Warm Afternoons
Patchy fog is expected to linger before 11 AM, with lows around 65°F, inland highs near 85°F and light south to southwest breezes of 0 to 10 mph. According to the National Weather Service, morning stratus will clear for most inland neighborhoods, while the immediate coast may stay cooler and cloudier. The agency also notes that a Heat Advisory is set to begin at 10 AM Sunday, July 12 and continue through 10 AM Tuesday, July 14 for many inland areas, with an Extreme Heat Watch possible from Tuesday morning through Thursday evening, July 14 to 16.
Monsoon Thunderstorms Possible
Monsoonal moisture is forecast to push north late Sunday into Monday, bringing about a 10 to 20 percent chance of showers and isolated thunderstorms, mainly over the Los Angeles and Ventura County mountains. Any isolated storms could deliver lightning, brief heavy downpours, and gusty outflow winds that may knock down visibility and trigger localized flash flooding in canyons and burn scars. Many neighborhoods will stay dry, but anyone planning outdoor events or relying on evening drives in and out of the hills should be ready for sudden, fast-hitting downpours.
Beaches, Surf, And High Tides
A south-to-southwest swell is expected to bump up surf and rip current risk at local beaches, while a higher tide on Monday, roughly 7.0 to 7.6 feet above MLLW, could combine with the swell to cause isolated minor coastal flooding in low-lying spots. Lifeguard warnings and beach hazard statements are possible beginning Sunday and into next week. If you are heading for the sand, build in extra time and keep an eye on posted beach advisories.
How To Stay Safe
For relief from the heat, call 211 or check the City of Los Angeles for cooling center locations and safety tips. Drink plenty of water, avoid strenuous outdoor activity during the hottest hours of the day, and never leave children or pets in parked cars, even for a short errand. Stay weather aware this weekend, since morning fog can slow commutes and mountain storms can build quickly.
