What to Expect from December Weather in Phoenix
Understanding local climate patterns helps you pack right and manage your daily itinerary.

Rainfall remains minimal throughout the month, averaging only about three rainy days across the entire thirty-one days. Sunshine dominates the forecast, giving you reliable conditions for hiking, golf, and patio dining. More journalism by Travel + Leisure explores similar perspectives on the subject.

Common Mistakes to Avoid
Travelers frequently make a few avoidable errors when visiting the desert in winter.
- Underestimating nighttime temperature drops: Do not assume that because it was 70 degrees at 2:00 PM, it will stay warm after dark. Temperatures plunge quickly once the sun sets behind the mountains.
- Skipping hydration: Because the air is dry and the weather feels cool, visitors often forget to drink enough water while hiking or walking around the city.
- Failing to book holiday events in advance: Signature attractions like the Desert Botanical Garden's light displays and resort holiday events sell out weeks ahead of time.
Frequently Asked Questions
Can you swim in outdoor pools in Phoenix in December?
Most standard outdoor hotel pools are unheated and will feel too chilly for comfortable swimming, as water temperatures drop significantly. However, many luxury resorts and boutique hotels feature heated pools and hot tubs specifically for winter guests.
Do I need a car to get around Phoenix?
While downtown Phoenix and areas like Tempe feature light rail transit, the metropolitan area is heavily spread out. Renting a car remains the most efficient way to reach trailheads, regional parks, and neighboring cities like Scottsdale or Mesa.
Is December considered peak tourist season in Phoenix?
Yes. Winter is high season in the Valley of the Sun because snowbirds and travelers flock to the region for the warm, dry weather. Expect higher demand for accommodations and busier weekends at major restaurants and attractions.
What clothes should I wear for desert hiking in winter?
Wear moisture-wicking layers that you can easily shed as you warm up on the trail. Long pants or trail leggings protect your legs from sharp cacti and brush, and a light windbreaker helps if a breeze picks up at higher elevations.
