Tucson, AZ – The Sonoran Desert wakes under clear skies and a still chill this morning, temperatures dipping into the low 40s before sunrise. The early cold won’t last long, though — by midday, sunshine floods the valley and highs will climb into the mid-60s, marking the start of a steady warm-up headed into the weekend.
According to the National Weather Service in Tucson, calm winds and clear skies will dominate through Sunday, with daytime highs rising near 72°F. Nights remain crisp, falling into the upper 30s to low 40s, but the wide temperature swing makes afternoons feel comfortably warm. Travelers can expect excellent visibility and dry conditions on major routes including I-10 and I-19, with no rain or wind hazards in sight.
This stable weather pattern offers a perfect stretch for outdoor activities — hiking Sabino Canyon, visiting downtown markets, or setting up early holiday lights. The calm won’t last forever, though; long-range models hint at a slight cool-down by mid-next week as Pacific air drifts inland. For now, Tucson remains one of the nation’s few warm-weather havens as much of the U.S. braces for Arctic cold farther north.
Residents are encouraged to watch for morning frost in outlying areas and use caution on shaded rural roadways where temperatures near freezing before dawn.
