Arizona is definitely one hot place to live. There are really no seasons in Arizona, as the sun is constantly shining, and it does not stay cold for a very a long time. The average temperature year-round is in the mid-70s. When packing your bags to come to Arizona State, bring all your favorite summer clothes because they will be your best friends for a good seven to eight months, and of course pack some jeans and coats for winter as it does get a little nippy. You will hardly see snow unless you decide to travel to northern Arizona, so don't bother packing your heaviest coat because it will take up way too much space in your closet. However, be prepared to bring at least some sweaters and jackets because the winter evenings do get pretty chilly, and fall can be somewhat crisp as well. Don't worry, though—it is not anywhere near the bone-chilling cold you would experience back east.
Humidity in Arizona is not too much of a concern due to the dry heat of the desert area. Summer can be fun if you're lounging next to a pool, but it can be a real issue when you have to walk across campus for a good 15 to 20 minutes and end up walking into class with a drenched T-shirt looking like you just passed through Death Valley. Overall, though, the weather has its ups and downs, but most students would agree that, as hot as Arizona is, you can at least find comfort in a nice, cool, air-conditioned building to escape the tormenting heat.
