TUCSON, Ariz. – A golden sunrise greets southern Arizona today, the kind that sharpens every desert ridge and cactus shadow. It’s a warm start to what may be the final stretch of true heat this fall. Afternoon highs climb into the mid-90s through Wednesday before the season’s first subtle cooldown arrives Thursday, offering a break from Tucson’s lingering summer feel.
According to the National Weather Service in Tucson, a light southerly breeze will hold today under clear skies, keeping conditions dry and stable across Pima County. By Wednesday afternoon, clouds may drift in from the northwest ahead of a weak trough pushing cooler air south. While no rain is expected, humidity dips again, leaving afternoons warm and evenings increasingly crisp. Lows near 58–60°F by Thursday and Friday will feel like the earliest hints of a seasonal shift — a sign that the “first fall freeze” may not be far off, especially in the higher foothills.
Travel on I-10 from Tucson to Benson remains easy this week, though drivers should stay alert for low morning glare and light crosswinds by Thursday. Outdoor workers and school athletics programs should plan hydration breaks through Wednesday, as dry heat and clear skies keep UV levels high.
By Friday and Saturday, Tucson’s days ease into the lower 80s under abundant sun — ideal for outdoor cleanup, Halloween decorating, or a sunset hike. Sunday may dip slightly cooler again, with lows near the mid-50s — a pleasant, steady turn toward true fall in the desert Southwest.
