Tucson, Arizona – Arizona’s brutal summer heat is back in full force as Tucson braces for triple-digit temperatures starting Thursday, July 24, with dangerous highs peaking near 107° by Sunday. Drivers and outdoor workers should prepare for prolonged exposure risks, especially along I-10 where road heat and dehydration hazards will intensify midday through evening hours.
According to the National Weather Service in Tucson, Thursday will mark the beginning of a high-pressure pattern, locking in daily highs of 100° or more through early next week. Winds will remain light and variable, offering little relief. Overnight lows in the upper 70s won’t provide much cooling, increasing the risk for heat-related illness without proper hydration and cooling.
Here’s how the next five days are shaping up:
- Thursday, July 24 – Sunny and hot, high near 100°. West-northwest wind 5 to 7 mph.
- Friday, July 25 – Sunny, high 103°. Clear overnight with a low near 75°.
- Saturday, July 26 – Scorching heat continues, high 104°, with little cloud cover.
- Sunday, July 27 – Peak heat arrives: mostly sunny and 107°. Overnight low near 80°.
- Monday, July 28 – Slight storm chances return (20%) with a high of 106°. Partly cloudy overnight, low around 80°.
- Tuesday, July 29 – Continued isolated storm risk (30%) with highs remaining near 103°.
⚠️ Safety Reminder: Limit strenuous outdoor activity from 11 a.m. to 5 p.m., check on vulnerable neighbors, and never leave pets or children in vehicles. More updates will follow if storm chances increase next week.
