Phoenix is forecast to reach 115 degrees Sunday, which would break the city's record high of 114 degrees set in 2025, as the National Weather Service extends its Extreme Heat Warning through Tuesday, according to Arizona's Family meteorologist Steven Sarabia. FOX 10 Phoenix and the NWS Phoenix office both confirmed the record-breaking forecast.
Monday offers little reprieve, with a forecast high of 114 degrees. The all-time Monday record stands at 116 degrees, set in 2024. The combination of extreme heat and low humidity will create dangerous conditions for outdoor activities, with officials urging residents to stay hydrated, check on vulnerable neighbors and family members, and limit time outside during peak heat hours.
Temperatures ease slightly Tuesday to a high near 111 degrees, but dew points climbing well into the 60s will make conditions feel nearly as hot as the previous two days. Highs drop to around 109 degrees Wednesday before returning to the 110 to 111 degree range Thursday through the end of the week.
A thunderstorm threat exists today and Monday across southeastern Arizona, with the greatest threat Monday. Outflow winds from those storms could push into Pinal County Monday evening, bringing gusty winds and blowing dust that could affect visibility and travel. A surge of monsoon moisture Monday night into Tuesday will increase humidity across the Valley, though rain chances in the Phoenix metro remain low.
The stubborn high-pressure system driving the prolonged heat may shift later in the week, opening a slight chance of showers and thunderstorms, with rain probabilities currently at 10% to 20%.
