Idaho Snow Day Forecast & School Closings
Idaho's snow day landscape stretches from the panhandle's Pacific Northwest moisture near Coeur d'Alene — where totals can exceed 70 inches — through the remote central mountain wilderness to the high desert of the Snake River Plain. Boise averages only about 19 inches, making it one of the driest state capitals in the snow belt, while mountain communities like McCall can exceed 100 inches. Districts spanning some of the most rugged terrain in the lower 48 make Idaho's closure decisions uniquely shaped by geographic isolation.

Snow Zones in Idaho
McCall, Sun Valley, and the remote central Idaho wilderness. The snowiest part of the state, with mountain communities routinely exceeding 100 inches. Road closures over passes can isolate communities for days. Schools close roughly 5–12 times per season.
Coeur d'Alene, Sandpoint, and Moscow. Pacific moisture feeds consistent snowfall, and the terrain ranges from lake valleys to mountain passes. Schools close roughly 4–8 times per year. Sandpoint and communities near the Canadian border see the heaviest totals.
Idaho Falls, Rexburg, and Pocatello. Moderate snowfall at high elevation with consistent cold. Proximity to the Tetons and Yellowstone region can amplify storm impacts. Schools close roughly 3–6 times per year.
Boise, Nampa, and Twin Falls. The lowest snowfall in the state due to the rain shadow of the Owyhee Mountains and the relatively low elevation of the valley floor. Boise averages roughly 19 inches — modest by Idaho standards. Schools close roughly 1–3 times per year.
The transition zone between the Snake River Plain and the mountain country. Twin Falls and surrounding communities see moderate totals. Freezing fog and black ice on rural roads are significant hazards. Schools close roughly 2–4 times per year.
Major School Districts in Idaho
Notable Winter Storms
A prolonged atmospheric river event buried Idaho's mountains and brought significant valley snow. Boise received a rare heavy event and mountain communities were isolated. Schools returning from break were closed across much of the state.
An unusual sustained snow event hit the Boise area, which is typically rain-shadow protected. Boise recorded over a foot — exceptional for a city that averages only 19 inches per year. Schools were closed for multiple days across the Treasure Valley.
Heavy snow and high winds hit the Idaho panhandle. Sandpoint and Coeur d'Alene received over 2 feet. Schools in the panhandle closed for multiple days and avalanche danger closed US-95 in several locations.
A major storm cycle dumped heavy snow across central Idaho and the panhandle. Flooding from rain-on-snow events compounded the impact. Schools closed and several communities experienced evacuations.
Snow Day FAQ
How many snow days does Idaho get per year?
Central mountain communities close roughly 5–12 times per season. The panhandle averages 4–8 closures. Eastern Idaho sees 3–6. Boise and the Treasure Valley typically close only 1–3 times per year.

What triggers a snow day in Idaho?
Thresholds vary enormously. Treasure Valley districts may close for 3–4 inches, while mountain districts handle much more before closing. Road and pass closures are independent triggers throughout central Idaho. Freezing fog and black ice on rural roads are additional factors across the Snake River Plain.
Does Idaho use virtual snow days?
Idaho allows remote learning days at district discretion. Larger Treasure Valley districts have adopted virtual options, but many rural and mountain districts face broadband limitations. Traditional makeup days and calendar buffers remain the norm in much of the state.
Which part of Idaho gets the most snow?
The central mountain wilderness — the Sawtooths, Salmon River country, and the area around McCall — receives the most, often exceeding 100–150 inches. Sun Valley and the nearby mountains also rank among the snowiest. Boise, despite being the state capital, sits in a rain shadow and averages only about 19 inches.
