Extreme Heat Wave to Impact Los Angeles and US Southwest
US · Published Jul 8, 2026
Temperatures across Los Angeles and the southwestern United States are set to rise significantly this week, with extreme heat already affecting Southern California and Arizona.
According to the National Weather Service, temperatures could reach as high as 116°F (47°C) in areas like Palm Springs and Phoenix through Thursday.

Impact & Risks

The extreme heat poses risks to vulnerable populations, including the elderly, children, and those with pre-existing health conditions. Prolonged exposure to high temperatures can lead to heat-related illnesses such as heat exhaustion and heat stroke. The heat wave may also strain energy grids, particularly in Texas, where the Electric Reliability Council of Texas (ERCOT) has faced challenges during previous heat events. Elevated temperatures increase the likelihood of wildfires in dry regions, particularly in Southern California and the northern Rocky Mountains.
