Arizona Winter Weather Overview
Arizona has a mostly desert climate, although higher elevations such as Flagstaff and the Mogollon Rim see significant winter snowfall. Statewide, the average annual snowfall is approximately 4 inches, with the heaviest snow typically falling between December and March. Notable historic snow events affecting Arizona schools include the February 2019 storm that brought rare snow across the state. Districts across Arizona report closing schools an average of approximately 1 days per winter season due to snow, ice, or extreme cold.
How Arizona Schools Handle Snow Days
School districts across Arizona make their own snow-day decisions, typically between 4:30 and 6:00 AM on storm days. Superintendents consult with road crews, transportation supervisors, and the National Weather Service before announcing closures, two-hour delays, or remote-learning days. In Arizona it is common for districts in the same metro area to make different calls based on local conditions. Closures are communicated through district websites, automated phone calls, local TV and radio stations, and increasingly through social media and parent alert apps.
