What to Wear in Phoenix in Winter: Month-by-Month Outfit Guide
Phoenix in winter sits in the 40 to 60°F range. This is the layer-by-layer outfit guide for Phoenix's winter weather — what to wear, what to pack for a visit, and the local context that shapes the recommendations.
WHAT TO EXPECT
40 to 60°F is the typical range for Phoenix in winter (December, January, February). December through February. The pleasant season. 65-75°F days, 40-50°F nights. Light layers, jeans, leather shoes, occasional sweater. The temperature range is the headline; what you actually feel depends on humidity, wind, and what indoor spaces you'll cycle through.
THE FOUNDATION LAYER
A lightweight merino or technical long-sleeve under your shirt or sweater handles the temperature swing.
THE MID LAYER
A cardigan, light fleece, or vest — pick based on whether you'll be active or stationary outdoors.
THE OUTERWEAR
A wool topcoat, trench, or insulated shell. A wool coat carries the look year-round if you live in the city.
ACCESSORIES
Wool scarf, knit hat for cold mornings, gloves for the commute. Boots over sneakers.
WHAT TO PACK FOR A TRIP TO PHOENIX IN WINTER
Three layer permutations covering the 40 to 60°F range, plus accessories. If your trip spans the season's edge (early March or late November), pack toward the cooler end of the range — overestimating warmth is easier to recover from than underestimating.
LOCAL CONTEXT
Dry heat behaves differently than humid heat. Sweat evaporates instantly. You can be dehydrated without feeling sweaty. Hydrate aggressively. Sun protection is non-optional year-round.
