It’s getting hot in here! Southern California’s first major heat wave of the summer will bring temperatures soaring into the triple-digits this week. The National Weather Service is forecasting high temperatures in the Los Angeles region today July 10 through Friday, July 11.
Heat Risk Throughout The Week
SoCal is warming up today as a high-pressure system from Arizona drifts into the region. Expect temperatures to climb into the 90s and even hit triple digits in some areas of Southern California by Wednesday and Thursday, when the heat wave peaks. The high pressure will settle over Southern California midweek, causing sinking air that compresses and intensifies the heat.
Expected SoCal Temperatures:
- The Inland Empire may hit upper‑90s to around 100°F.
- The L.A. basin may climb into the 80s–90s.
- The coast is expected to stay cooler in the 70s.
The National Weather Service has issued an Excessive Heat Warning for areas between Palm Springs and Blythe from Wednesday at 10 a.m. to Thursday at 8 p.m., while the Inland Empire will be under a heat advisory during the same timeframe. Of course, this also means an elevated risk for wildfires in the area.
Cooler weather is expected by Friday as the high pressure eases and onshore breezes return, bringing some relief for the weekend. However, that relief won’t last long as there’s already another heat wave in the forecast for next week.
“As we experience high temperatures this week, I urge Angelenos to stay safe, stay cool and stay hydrated,” said Mayor Karen Bass in today’s press release. “While peak heat is expected Wednesday, July 9, and Thursday, July 10, City resources are available throughout L.A. all week for Angelenos to beat the heat.”
How To Stay Safe During A Heat Wave
- Stay Hydrated: Drink plenty of water throughout the day.
- Stay Indoors: If possible, stay indoors during the hottest parts of the day when the sun is at its highest point.
- Seek Shade: If you must be outside, seek refuge from the sun. Limit your exposure to direct sunlight between 10:00 AM and 4:00 PM, when the sun’s rays are strongest.
- Use Air Conditioning or Fans: Keep your home cool with air conditioning or fans. If this is not a possibility, consider visiting a cooling center or public places like malls or libraries.
- Avoid Strenuous Activities: Postpone outdoor activities or exercise during the hottest parts of the day.
- Check on Vulnerable Individuals: Regularly check on pets, elderly family members, neighbors, and those with chronic medical conditions who may be more susceptible to heat-related illness.
