Although it's possible to encounter snow in Tucson, it isn't very likely. With average lows above 40 degrees Fahrenheit throughout the winter (December-March), snow is a rare occurrence in the city. Because of the area's temperate weather, winter is one of the most popular seasons for traveling to Tucson. Visitors leaving behind colder weather welcome daily highs that top 70 degrees Fahrenheit by February. You'll likely find snow atop the Santa Catalina Mountains northeast of the city, so for an unforgettable wintertime experience, go on a scenic tour of Mount Lemmon. This mountain is the highest peak of the Santa Catalina range and is just a short ride from the heart of Tucson.
