Southern California braces for triple-digit temperatures as heat wave strengthens
Triple-digit temperatures and warm nights will raise heat-illness risk, while officials warn of increased wildfire danger and urge residents to take precautions.
- On Monday, August 24, 2026, Southern California faced triple-digit temperatures as a prolonged heat wave intensified across the region with extreme conditions forecast throughout the week.
- High pressure aloft causing "compressional warming" drives the heat wave, with NWS meteorologist Ryan Kittell explaining that northerly wind shifts bring further temperature increases to the region.
- Inland areas will see highs of 100 to 110 degrees through Saturday, with overnight lows remaining 8 to 12 degrees above normal, exacerbating heat stress as bodies cannot cool overnight.
- Health officials urge residents to "drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." The NWS also warned of "increased risk for large plume-dominated fire behavior."
- Peak conditions are expected Tuesday through Thursday, with temperatures remaining hot into next weekend; however, the NWS notes past heat waves have historically lasted longer than forecasts predicted.
