SPRING in Arizona – (March, April, May)
By spring, Arizona is getting considerably warmer, particularly in the western part of the state. In the northern part of the state, high temperatures will likely stay around 50 degrees Fahrenheit, while elsewhere, temps could get up to 80 degrees. Layers are a must.
SUMMER in Arizona – (June, July, August)
Summers in Arizona can be exceptionally hot. Temperatures across the state will likely be in the 90s, but in the southern desert, temperatures can get up to 125 degrees Fahrenheit. Light, quick-drying fabrics are essential.
FALL in Arizona – (September, October, November)
Fall is perhaps the most pleasant time of year in Arizona. Temperatures are still warm (in the 80s) but evenings are cool. If you find desert heat unbearable, fall might be the ideal time to go. Again, layers are great, and you’ll want to bring at least a light jacket.
WINTER in Arizona – (December, January, February)
Temperatures can vary widely during winter and can still occasionally be quite warm. Nighttime temps typically average in the 40s, and there may be snow in the northern, high altitude part of the state. You should definitely pack cold-weather attire, but a light jacket may suffice if you’re sticking to the southern part of the state.
