Arizona’s weather is popularly categorized as hot and dry, but what most people outside the state don’t realize is that Arizona’s climate is actually quite varied.

While Central Arizonans are basking in mild weather with cool breezes in January, folks in Northern Arizona might be swooshing down the state’s ski slopes enjoying a cool winter day. And in the summer, Southern Arizonans could be sunbathing, while people in North-Central Arizona might slip on sweaters and enjoy the crisp night air.

No matter what time of year you visit Arizona, you’ll find beautiful, perfect weather somewhere.¬†For complete information about Arizona’s weather, visit the National Weather Service.
