Story summary

Southern California is currently experiencing an unusually severe late-season heatwave that began on Friday, with temperatures expected to reach up to 100°F in downtown Los Angeles and exceed 100°F inland. This prolonged period of extreme heat, which will last at least a week, poses significant risks including heat-related illnesses and potential wildfires. The National Weather Service (NWS) warns that temperatures are 15-20 degrees above normal, with conditions exacerbated by an ongoing marine heatwave contributing to a strong El Niño event.

On Monday alone, downtown Los Angeles broke its previous record for October 5th, reaching 104°F. Similarly, Santa Ana recorded a high of 106°F, surpassing the old daily record set in 1953. The NWS issued extreme heat warnings from Santa Barbara to San Diego, advising millions of residents to limit outdoor activities and stay hydrated.

As of Sunday, at least 37 million people across California are under heat alerts as temperatures soar up to 20 degrees above normal for this time of year, affecting areas from the San Francisco Bay Area to the Mexico border.
