Tucson, Arizona – Scorching heat builds across southern Arizona this week, with Tucson climbing toward triple-digit highs by Thursday and peaking near 105°F by Sunday.
According to the National Weather Service, light and variable winds will increase slightly on Wednesday, reaching gusts up to 20 mph by midday. Wednesday’s high will approach 95°F, with dangerous dry conditions and strong sun exposure expected throughout the day. Residents should limit outdoor activity during peak heat hours and stay well-hydrated.
By Thursday, Tucson will push to 98°F under clear skies with calmer west winds. Friday marks a critical jump, as the city could hit 101°F by afternoon. Saturday and Sunday look even hotter, with highs forecasted at 103°F and 105°F respectively, amid minimal nighttime cooling. Overnight lows will stay in the upper 60s to low 70s, offering little relief for those without air conditioning.
Expect increased fire weather risks this week due to dry air and variable winds. Pima County residents should avoid open flames and monitor emergency alerts. Those traveling along I-10 and AZ-86 should prepare for heat-related car trouble and pack extra water.
Cooling centers may open by the weekend. Officials recommend checking on elderly neighbors and limiting strenuous activity outdoors.
