Desert mornings start crisp and calm across Phoenix, with the air holding near 50°F under crystal-clear skies. As the sun rises over the Valley of the Sun, warmth builds quickly — signaling another string of near-perfect December weather for the metro area.
According to the National Weather Service in Phoenix, expect clear skies and highs near 73°F today, with calm winds and no sign of rain. Tuesday and Wednesday will bring nearly identical conditions, with highs climbing into the mid-70s and lows staying mild around 47–50°F.
By Thursday and Friday, temperatures rise further — reaching 77° to 79°F — a full 10 to 15 degrees above seasonal averages. While most of the nation braces for arctic air and heavy snow, Arizona enjoys a warm, tranquil stretch that’s ideal for outdoor work, travel, or early holiday decorating.
Air quality will remain stable under light winds, though morning haze or patchy dust may linger near highways and construction zones. Drivers should expect bright glare and dry conditions through late week, perfect for commuters and travelers heading toward Interstate 10 and Loop 101.
Looking ahead, this mild pattern holds into the weekend before a slight cool-down early next week — but for now, the Arizona sunshine reigns supreme.
