Downtown Los Angeles is in for a scorcher on Thursday, July 16, with forecasters calling for a high near 92°F under full sun and light southerly breezes. An Extreme Heat Warning remains in place for parts of the county through 8 p.m., heightening the risk of heat-related illness for anyone stuck without air conditioning.
Heat Today: Peak Afternoon Danger
The real punch comes in the mid-to-late afternoon. Downtown is expected to top out near 92°F, while inland valley neighborhoods crank things up even higher, some reaching roughly 100–106°F, according to NWS Los Angeles/Oxnard. Light south winds around 0–10 mph will offer little relief, and the most dangerous window looks to be from about 2–5 p.m. If you can, shift workouts, yard work, and errands to the morning or evening to avoid the worst of the heat.
Overnight, Fog And A Short Cool-Down
Overnight temperatures downtown only slip into the upper 60s, which means not much cooling for anyone trying to sleep without air conditioning. By Friday morning, patchy fog may develop near the coast and in some low-lying spots. A modest onshore trend will shave a few degrees off daytime highs heading into the weekend, with temperatures dipping into the low to mid-80s Friday and Saturday as the marine layer creeps back in during the mornings.
Where To Cool Off And Safety Tips
If you do not have reliable air conditioning, the county and city operate cooling centers during heat events, so you can call 211 or visit 211 LA County to find a nearby site. Staying hydrated, never leaving children or pets in parked cars, and avoiding strenuous outdoor work during peak afternoon heat are simple steps that can help prevent heat exhaustion and heat stroke. Employers and outdoor crews should build in frequent shade breaks and keep an eye out for anyone showing signs of overheating.
Bottom Line
The Extreme Heat Warning runs through 8 p.m. Thursday, so keep outdoor plans to the cooler morning and evening hours and take advantage of cooling resources if you need them. Updates will follow if the warning changes or if additional heat advisories are issued in other parts of the region.
