TUCSON, Ariz. – Pale gold sunlight is breaking over the Catalina Mountains this morning, revealing another warm and crystal-clear start to southern Arizona’s Halloween week. Breezy east winds are stirring dust along the I-10 corridor, and by late morning, gusts could reach 25 mph—enough to rattle patio furniture and toss lightweight decorations.
According to the National Weather Service in Tucson, dry air remains firmly in place under a blocking ridge, keeping skies sunny and temperatures well above late-October norms. Highs near 87° today and upper 80s on Thursday will make afternoons feel more like early fall than the start of winter. Those planning outdoor school events or afternoon commutes should brace for steady east winds, especially across open desert roads south toward Sahuarita and Benson.
Halloween Friday looks nearly perfect for trick-or-treating, with bright sunshine early and calm, dry air by sunset. Evening temperatures will hover around 70° at dusk, dipping only into the low 60s late—comfortable enough for light costumes without jackets. Roads and sidewalks will stay dry, and no rain or dust impacts are expected for events across Pima County.
Looking ahead, models hint at a slight cool-down starting Saturday as northwest breezes return. Highs should ease into the mid-80s, a pleasant shift for late-fall cleanup and early decorating before November’s chill sets in. To be fair, Tucson’s streak of cloudless skies can’t last forever—long-range trends point toward cooler, possibly wetter conditions by mid-November.
After all, clocks fall back early Sunday at 2 a.m., signaling darker evenings and the real start of the Southwest’s slow slide into winter.
