Snow day calculator Alaska
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.
Alaska schools usually close around 10 inches of overnight snow. Anchorage closes for ice and extreme cold more than for snow; a foot overnight is a strong case. The meter below opens on Anchorage; type your ZIP or town and it reads tonight's hourly forecast for your exact spot and scores it against the Alaska threshold.
How much snow it takes in Alaska
Snow is the normal condition of an Alaska school day, so the amount of it rarely decides anything. Anchorage averages 77.9 inches a season and about 22 days a year with an inch or more of new snow; Juneau averages 87.6 inches and Fairbanks 64.6. Districts own the plows, the buses run on studded tyres, and a six-inch night is a Tuesday.
The model sets the Alaska threshold at 10 inches overnight and leans on the other terms instead: freezing rain, which Anchorage gets when a Pacific warm front rides over cold valley air, wind, and extreme cold. In Fairbanks the cold term matters more than anything that falls from the sky. A foot of snow still falling at bus time is a strong case; a foot that stopped at midnight usually is not.
The way Alaska talks about this changed in December 2024. The state education commissioner said remote 'e-learning days' for weather would be reconsidered and that the expectation is to make the days up, and the Anchorage School District dropped remote weather days and went back to plain closures.
Alaska winter by the numbers
| Station | Snow per season | Days with 1″+ | Days with 3″+ | Snowiest month |
|---|---|---|---|---|
| Anchorage | 77.9″ | 21.8 | 8.6 | Dec |
| Fairbanks | 64.6″ | 21.0 | 4.6 | Nov |
| Juneau | 87.6″ | 23.1 | 9.9 | Jan |
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 Alaska
Alaska requires 180 days in session (AS 14.03.030), with up to 10 in-service days allowed to substitute, or an hours-based term of 740 hours for kindergarten to grade 3 and 900 hours for grades 4 to 12. A superintendent may order an emergency closure when it is needed to protect the health or safety of students, staff or the community, and must notify the state education department within 24 hours (4 AAC 05.090).
After a closure the district files a modified calendar. If the year would fall below 170 days in session, the commissioner has to approve the closure days as emergency days or the district must add make-up days; the regulation lets the commissioner approve all, none or some of them, and one factor is whether the district kept education going during the closure. That is the mechanism the 2024 policy shift leans on: a remote day no longer earns an automatic pass.
- Minimum school year
- 180 days in session, or 740 / 900 hours (AS 14.03.030)
- Closure floor
- Below 170 days needs a commissioner waiver or make-up days (4 AAC 05.090)
- Who decides
- The district superintendent, with notice to the state within 24 hours
- Regular districts
- 54 (NCES, 2021-22)
Questions people ask
- Why does Anchorage close for ice and not for snow?
- Because snow is what the district is equipped for. Anchorage averages 8.6 days a year with 3 inches or more and 3.6 days with 5 inches or more, and the buses run through all of it. Freezing rain on top of packed snow is a different problem: in December 2024 freezing rain and road conditions were what pushed Anchorage and Mat-Su schools to remote or closed days.
- Does Fairbanks close for cold?
- Rarely on cold alone; Interior Alaska runs school at temperatures that would close any Lower 48 district. The meter still scores wind chill at bus time, and the cold-day calculator on this site is the better tool when the forecast is clear and brutally cold rather than snowy.
- Are remote learning days still used for Alaska snow days?
- Less than they were. In December 2024 the state commissioner said e-learning days would be reconsidered and that districts should make lost days up, and the Anchorage School District announced it was dropping remote weather days. Check your own district's current policy; the meter scores closures and delays, not the make-up method.
- How many snow days can an Alaska district take?
- There is no fixed number. The regulation sets a floor of 170 days in session; closures that would drop a district below it need the commissioner's approval as emergency closure days, or the days get added back at the end of the year.
