Phoenix is back in the oven on Thursday, July 9, 2026, with clear skies and relentless heat locking in across the Valley. By midday, Sky Harbor was already in the low 90s and temperatures are on track to peak near 113°F this afternoon. Overnight will not offer much of a breather either, which means anyone spending time outside faces a higher risk of heat-related illness.
Extreme Heat Warning and the Afternoon Peak
An Extreme Heat Warning stays in effect into Friday evening for much of the lower desert, with afternoon highs near 113°F and heat index values running about 110 to 111°F. West-southwest winds should remain mostly light, with some gusts up to 20 mph in spots. The result is a prolonged period of Major HeatRisk across the Phoenix metro, where heat cramps and heat exhaustion are possible without shade, water, and frequent breaks. The National Weather Service notes that widespread overnight lows will linger in the upper 80s, which limits how much relief people get from the daytime heat.
Nighttime Relief Will Be Hard to Find
Forecasts keep metro overnight lows hovering around 88 to 91°F, so air conditioning or access to a cool refuge will be important for both sleep and safety. When nights stay this warm, bodies do not recover as easily between heat exposures, adding extra strain for older adults, people with health issues, pets, and even the local power grid.
Plan Outdoor Work and Travel Carefully
To reduce risk, shift heavy outdoor work and workouts to early morning or later in the evening whenever possible, drink plenty of water, and take frequent breaks in the shade. Expect light afternoon breezes that can occasionally gust, along with the chance of dust or outflow winds if storms manage to build over the higher terrain later in the weekend.
Cooling Centers and Local Help
If you need a cool place to ride out the heat, call 2-1-1 to get connected with nearby cooling centers, respite sites, hydration stations, or transportation options. Maricopa County runs an interactive Heat Relief Network map and other resources aimed at helping vulnerable residents stay safe. Visit Maricopa County for details and locations.
Looking Ahead
Forecast models show temperatures easing just a bit starting Friday and into the weekend, with highs sliding from the low 110s toward the upper 100s for many neighborhoods. Moisture is expected to increase late this weekend into early next week, which brings a growing chance of afternoon and evening showers or thunderstorms beginning Sunday. Some spots could see localized downpours and brief gusty winds, but overall rainfall totals are still expected to stay on the light side.
