Phoenix, AZ – The first full week of December opens with a crisp desert calm as the Valley wakes to cool air under clear skies. By sunrise, a light breeze moves through the east side of the city, carrying just a hint of winter cool. For travelers, this stretch brings welcome relief: no rain, no wind advisories, and bright sun dominating the Arizona skyline through the weekend.
According to the National Weather Service, temperatures will climb steadily through the next several days—peaking near 71°F by Sunday. Mornings, however, will remain brisk, dipping into the low 40s before dawn. The region’s clear skies and calm air will keep visibility excellent, though early drivers should still watch for localized patchy frost in shaded or higher-elevation areas north of Phoenix.
For those flying in or out of Sky Harbor International Airport, travel conditions remain ideal. Calm winds and dry air continue through Saturday, offering smooth air travel and no anticipated delays. Outdoor events, from local farmers markets to holiday light displays, should enjoy mild daytime warmth and cool, comfortable evenings.
Looking ahead, long-range models hint at a modest temperature dip by mid-next week, as cooler desert air pushes in from the north. Though no rain is in sight, forecasters suggest a more typical December chill could settle by Wednesday—just in time to remind residents that winter is edging closer.
