Record Humidity and Marine Heat Wave Impact Southern California
Southern California is experiencing unprecedented humidity levels, marking the most humid summer in 46 years for cities like Santa Barbara, Los Angeles, Long Beach, and San Diego (Los Angeles Times, 2026). This phenomenon is attributed to a marine heat wave in the Pacific Ocean, ongoing since May 2025, and a strengthening El Niño event off South America. On September 9, Los Angeles recorded a dew point of 76°F (24°C), described as 'oppressive' by the National Weather Service. Experts warn that these conditions may signal lasting effects of global warming, with temperatures rising relentlessly and breaking records month after month.
