Southern California faces extreme heat and high humidity

Southern California is experiencing a period of extreme heat and high humidity, with the National Weather Service warning of a “very high heat risk” for at least one more day. The weather event, driven by a high-pressure system from Arizona and offshore winds, has led to multiple temperature records.

In Long Beach, temperatures reached 107 degrees, surpassing the previous 2015 record. Downtown Los Angeles tied a previous record with 105 degrees, while Escondido recorded its hottest day since recordkeeping began in 1893. Other areas, including Camarillo, Oxnard, Santa Barbara, and Santa Maria, also reported temperatures above prior marks.

Public health officials have noted that the combination of heat and humidity increases risks for vulnerable populations, including children, older adults, and those without air conditioning. The weather has also impacted local infrastructure and education; for instance, the Torrance Unified School District reported that classroom temperatures reached record-breaking levels.
