When you visit Tucson, you have to realize you’re coming to a desert, the Sonoran Desert to be exact, and that means everything you’d expect weather-wise—scorching hot summer days, a toastier-than-average winter and very little in the way of precipitation....but it can get chilly, even in the desert, at night.

If you plan on coming to the city in the summer, make sure you know you’re in for 100-degree plus days and night-time temperatures you’d expect at noontime elsewhere around the country—low 80s is about average. Luckily, humidity is generally very low at this time and you can just about always expect clear skies and amazing sunsets!

The second half of the summer ushers in what the locals call "the monsoon season."  Typically beginning around July 4th and lasting through mid-September is a period of increased rainfall and nasty humidity.  Monsoon storms roll in fast, usually in the late afternoon, and generate a lot of lightning and scary loud thunder.  Be cautious when driving on roads with washes or ditches: flash floods do occur fast and without warning before, during and after a monsoon and are very dangerous.

The upside of the desert climate is that even in the dead of winter, temperatures rarely dip below 60 degrees during the day. However, the nights in December, January , and February can get pretty chilly, often dipping below freezing.  Through Arizona is known as a stereotypical "hot" state, it is advisable to pack a jacket as the temperature can change dramatically without warning in the winter or you might be buying one when you get here.  Yes, you'd be surprised but it really can get cold, even in Tucson!

It’s best to plan your trip trying to catch the time in between the two long seasons. Mid-February through Mid-May and Mid-September through November generally reward travelers with dry days in the 70s or 80s and nights in the 40s or 50s. If you don't mind cold night-time weather, December is generally mild and often warm in the day with temperatures dropping radically at night.
