Phoenix Endures Record-Breaking Heatwave with Temperatures Reaching 115°F (46°C)
US · Published Sep 7, 2026
Phoenix, Arizona, is currently experiencing one of its most intense heatwaves in recent history, with temperatures consistently reaching 115°F (46°C) during peak afternoon hours (source: DEEPER, 2026-09-07).
The National Weather Service has issued excessive heat warnings as a strong upper-level ridge, or 'heat dome,' traps hot air over the region.

Impact & Risks

The ongoing heatwave is causing widespread impacts across Phoenix. Power grids are under immense strain, with the risk of rolling blackouts due to increased energy demand for air conditioning. Roadways are softening, leading to infrastructure damage such as potholes and deformations. Vulnerable populations, including the elderly, children, and pets, are at heightened risk of heat-related illnesses. Animal welfare organizations have reported a rise in heatstroke cases among pets left outdoors. The prolonged nature of the heatwave is particularly concerning, as it leaves little time for recovery during cooler nighttime hours.
