PHOENIX, Ariz. – Desert heat refuses to ease as Phoenix heads into another week of triple-digit highs, with temperatures topping 103°F by Tuesday. Residents should limit time outdoors during peak afternoon hours and carry extra water when traveling, especially along I-10 and Loop 101 where traffic delays can increase heat risks.
According to the National Weather Service in Phoenix, Sunday will bring plenty of sunshine with highs near 99°F before temperatures rise sharply early next week. By Monday, the city climbs to 102°F, followed by 103°F on Tuesday, with little relief overnight as lows only drop into the upper 70s.
The unrelenting sunshine creates dangerous conditions for outdoor workers and vulnerable groups, including children and older adults. Health officials urge residents to avoid strenuous activities during midday, stay hydrated, and check on neighbors without reliable cooling. Drivers should store extra water in vehicles and avoid leaving pets or children inside parked cars.
Clear skies will continue through Wednesday with highs remaining above 100°F. Winds will stay light, offering little help against the daytime heat. By Thursday, some relief could come as a slight chance of showers and thunderstorms returns, though conditions remain mostly hot and dry until then.
Warnings remain in place for the Phoenix area through midweek, and officials advise residents to remain prepared for prolonged heat.
