Snow day calculator Maine
Best time to check
- The evening before, after 9 pm
- The evening model runs are in by then and the forecast here refreshes every 30 minutes. A number read at 6 pm can move by several inches of snow before midnight.
- The morning of, 5 to 7 am
- The strip above shades 4 to 7 am. Snow still falling in those hours lands on the commute, so the model counts it extra, and most districts have decided by the time the buses roll at 7.
When districts actually decide
- Portland Public Schools, Oregon publishes its closure decision no later than 5 am (read 10 Oct 2026)
- Omaha Public Schools announced the 23 January 2026 cold closure at 5:50 pm the evening before (read 10 Oct 2026)
- Little Rock School District announced a two-day closure the afternoon before the 9 January 2025 storm (read 10 Oct 2026)
- Minnesota e-learning days must be announced at least two hours before the normal start time, by statute (read 10 Oct 2026)
Every district sets its own cut-off; these are published examples, not a rule.
Maine schools usually close around 6 inches of overnight snow. Six inches overnight or ice; Mainers delay first and close when the plows cannot keep up. The meter below opens on Portland, Maine; type your ZIP or town and it reads tonight's hourly forecast for your exact spot and scores it against the Maine threshold.
How much snow it takes in Maine
Maine delays first and closes when the plows cannot keep up. Portland averages 68.7 inches a season with 8.1 days of 3 inches or more and 5 days of 5 inches or more; Bangor 74.6 inches; Caribou in the County 118.2 inches and 13.1 days of 3 inches or more. January is the snowiest month on the coast and February up north. The model's 6-inch threshold is where a full closure becomes common; 3 to 5 inches is usually a two-hour delay.
Ice and timing move it. On 6 February 2025 a storm of 3 to 6 inches arriving at the morning commute closed districts across southern Maine, including Portland, well under the threshold, because the snow was falling hardest at bus time. The state fields 430 plow trucks and 850 drivers over 8,800 lane miles with 85,000 tons of salt on hand, but the town roads are the towns'.
Maine is also one of the states where a remote day can count, with a condition that is pure Maine: the school has to feed the students.
Maine winter by the numbers
| Station | Snow per season | Days with 1″+ | Days with 3″+ | Snowiest month |
|---|---|---|---|---|
| Portland | 68.7″ | 16.4 | 8.1 | Jan |
| Bangor | 74.6″ | 20.6 | 8.7 | Jan |
| Caribou | 118.2″ | 30.0 | 13.1 | Feb |
1991-2020 climate normals for the airport or first-order station in each city, read 2026-10-10 from the NOAA NCEI U.S. Climate Normals. “Days with 3″+” is the average number of calendar days a year with at least 3 inches of new snow.
How closures are decided in Maine
Maine schools must be maintained for at least 180 days a year with at least 175 used for instruction (20-A M.R.S. 4801), and an instructional day is at least three hours, averaging five over two weeks. A cancelled day is expected to be rescheduled. The statute's own make-up device is the one-hour extension: five one-hour extensions of the school day count as one additional day, up to 25 extensions or five days a year, under a commissioner-approved plan, and only to make up weather or emergency closures. The commissioner may reduce or waive the day minimum on a school board's application, but only after the district has exhausted all reasonable ways of making the days up.
A remote day counts toward the 175 if the school administrative unit provides meals to students and meets the instructional-day requirements; a closure with no meal service or remote learning does not count. There is no cap in the guidance we could read. Districts set their own mix: Portland Public Schools' 2025-26 plan is three traditional snow days, then remote learning days. The 256 regular districts and unions each make the closure call.

Questions people ask
- Does a remote day count as a school day in Maine?
- Yes, if the school unit provides meals to students and the day meets the instructional-day rules. A closure with no meal service and no remote learning does not count. Portland Public Schools, for instance, plans three traditional snow days a year and then switches to remote days.
- How do Maine schools make up snow days without adding June days?
- By adding an hour to the school day. Five one-hour extensions count as one make-up day, up to 25 extensions or five days a year, under a plan approved by the commissioner, and only for weather or emergency closures.
- Is 4 inches a snow day in Portland?
- Usually a delay. Portland averages 8.1 days a year with 3 inches or more, so towns are built to plow that overnight. Closures become common from about 6 inches, or whenever heavy snow or ice lands on the morning commute, as on 6 February 2025.
- Does Aroostook County close more than the coast?
- Less often per inch. Caribou averages 118.2 inches a season and 30 days a year with an inch or more, so the County is set up for routine snow and closes for storms and wind that the coast rarely sees. The meter reads the forecast for your coordinates and scores it against the same 6-inch threshold.
