Downtown Los Angeles started the day wrapped in a shallow marine layer, but that cool, gray ceiling is temporary. By afternoon, temperatures are expected to rocket toward 89°F, kicking off a stretch of warm, sticky days where shade, water and air conditioning are going to feel less like luxuries and more like survival gear.
What To Expect Today And This Week
The National Weather Service has a Heat Advisory in place through 10:00 a.m. PDT on Tuesday, July 14, with an Extreme Heat Watch lined up for Tuesday through Thursday next week. Inland neighborhoods will take the worst of it. Downtown is forecast to peak near 89°F today, with nearby inland valleys climbing into the upper 80s to low 90s on the hottest afternoons and overnight lows generally stuck in the mid 60s.

Morning Fog, Sunny Afternoons
The marine layer will keep parts of the coast and nearby valleys socked in early, with patchy fog most likely before mid-morning on Friday and Saturday. By late morning, the sun should punch through and clear out the low clouds, setting up bright, warm afternoons. Winds will stay on the light side, out of the south to southwest at about 0–10 mph, which means you should not count on much ocean breeze to cool inland spots during peak heat.
Cooling Options And Safety
If your place does not have air conditioning, the city’s network of more than 70 library branches and park facilities can function as cooling spots during heat events. You can call 3-1-1 or check the city’s current list for locations and hours before you head out. Wherever you ride out the heat, bring water, go easy on heavy exertion during the hottest hours, and keep an eye on older neighbors or anyone who might not have access to cool shelter. Local resources are listed on the LA City heat page.
Plan Ahead
Try to avoid strenuous outdoor work during the peak of the afternoon, and shift events or chores to the morning or evening when you can. Take frequent water breaks if you have to be outside. And do not leave children or pets in parked cars at any time; interior temperatures can jump to deadly levels in just minutes.
Looking Ahead
Monsoonal moisture may drift into Southern California over the weekend, briefly cranking up the humidity and adding a small chance of showers and thunderstorms over the mountains before temperatures climb again by mid next week. Keep an eye on updated forecasts and advisories as conditions evolve, because this pattern is not done with downtown yet.
