Snow days in Maine

Maine districts are used to snow: plows and salt trucks run through the night, and most schools stay open for a few inches. Closings come with big overnight storms, ice, or wind chills cold enough to make waiting for a bus dangerous – the decision is usually made between 5 and 6 AM.

FAQ

Maine snow day questions

Will there be a snow day in Maine tomorrow?

Tomorrow is Saturday. The highest chance among Maine's largest cities is 1 % in Portland (0.0 in of snow forecast overnight).

How much snow closes schools in Maine?

Around 6.5 inches overnight gives an even chance in most Maine districts; extreme wind chills close schools too. Mountain and rural districts with long bus routes close earlier than city districts.

How accurate is it?

As accurate as the forecast and as predictable as your district. Snow forecasts the evening before are usually within an inch or two; ice and the timing of a storm are harder. Districts also weigh things the forecast cannot see – bus routes on hills, whether plows can finish by 6 AM, how many days they have already used. Treat 50 % as a coin toss and check again at night and early in the morning.

What makes schools close besides snow?

Ice is the most common reason in the South and the Mid-Atlantic: a tenth of an inch of freezing rain makes roads more dangerous than several inches of snow. In the northern plains and the Upper Midwest, dangerous wind chills (often −25 to −35 °F) close schools even without snow, because children wait for buses outside.
