The desert sky glows pale gold at sunrise across Phoenix, the chill of early December fading quickly under a brightening sun. A light breeze ripples through palm fronds, and the still air promises a tranquil stretch of weather for the days ahead.
After a cool start in the mid-40s, temperatures climb steadily toward the low to mid-70s by afternoon — a picture-perfect reminder of why December in central Arizona draws winter travelers. According to the National Weather Service, this calm pattern continues through midweek with little change: clear skies, light winds, and mild evenings.
Commuters and travelers can expect ideal driving conditions along I-10, Loop 101, and Route 60, with no precipitation or wind hazards in sight. Mornings may still feel crisp before sunrise, but the afternoons will warm quickly under strong desert sunshine.
By Tuesday and Wednesday, high pressure strengthens, nudging daytime highs near 75°F — about 5 to 7 degrees above seasonal averages. The air remains dry, and visibility will stay excellent for those flying out of Sky Harbor International Airport.
Looking ahead, this tranquil pattern holds through Friday, with only a slight uptick in clouds late next weekend as Pacific systems pass north. Northern Arizona may see cooler air by December 14–16, but Phoenix stays mild.
