Why the Weather Changes So Much Across Arizona

The quick shift from desert warmth to mountain cold happens because of elevation.

Phoenix & Tucson sit in low desert basins: mild winter temperatures and sunny days.
Sedona sits higher at 4,300 feet, which cools the air and creates crisp winter conditions.
Flagstaff is over 7,000 feet in elevation—high enough for heavy snowfall and freezing nights.

Just a two-hour drive can take you from blooming desert trails to snow-covered pine forests.

Sunshine, Dry Air & UV Index

Even in December, Arizona’s UV index stays strong. The sun reflects off red rocks, snow, and pale desert sand. The dry winter air can also feel surprisingly sharp.

Keep in mind:

Sunscreen is important year-round
Hydration is essential (even when it isn’t hot)
Sunglasses and hats reduce glare
Lip balm and moisturizer prevent dryness

What Weather to Expect

A typical December day might look like this:

Morning: 35–45°F, chilly, layered clothing needed
Afternoon: 55–70°F, warm sunshine perfect for outdoor activities
Evening: 40–50°F in the desert, 20–30°F in the mountains
Night: Crisp, cold, and stargazing-friendly

Arizona mornings and evenings cool down quickly once the sun sets behind the mountains, so having a light jacket or fleece always helps.
