Phoenix, Arizona – Unrelenting heat will grip central Arizona starting Thursday as Phoenix heads toward its first 104°F reading of the season by Saturday.
According to the National Weather Service in Phoenix, a prolonged warming trend will begin Thursday with sunny skies and a high near 93°F. Friday will reach 101°F, and Saturday could soar to 104°F — unseasonably hot even for early May. Winds remain light, but low humidity and clear skies will drive rapid daytime heating across Maricopa County and surrounding areas.
Valley residents should limit outdoor activity during peak hours, especially between 11 a.m. and 4 p.m., and stay hydrated. Those traveling on I-10 or I-17 should ensure their vehicles are heat-ready to avoid roadside breakdowns. Elderly residents and outdoor workers are especially vulnerable during these temperature spikes. The city’s heat relief stations are now open and can be located via the Maricopa Association of Governments website.
Looking ahead to Mother’s Day on Sunday, May 11, temperatures remain dangerously warm with a high near 104°F again expected. Winds may gust up to 20 mph Sunday afternoon, compounding the heat.
