Nunavut Snow Day Predictor — Iqaluit, Rankin Inlet, Cambridge Bay and All Nunavut Communities
Nunavut Snow Day Predictor
Canada's most accurate snow day predictor
Check tonight’s school closure probability for schools across Nunavut — Canada’s largest and most remote territory. Updated every hour using live Environment Canada weather data calibrated for Arctic extreme cold, ground blizzards, and polar conditions. Nunavut’s school closure environment is unlike anywhere else in Canada: extreme cold to −50°C+, extended polar darkness in High Arctic communities, and blizzard conditions with no topographic wind protection.
Nunavut Snow Day Triggers — Cold, Blizzards, and Polar Conditions
- Extreme Cold (primary trigger): Apparent temperatures below −40°C to −50°C create genuine frostbite risk within minutes for children outdoors. Our algorithm applies the highest cold-event weighting of any location in our Canadian database for Nunavut communities.
- Blizzard and Ground Blizzard Conditions: On open Arctic tundra with no topographic protection, high winds lift previously fallen snow, creating near-zero visibility at ground level — sometimes with completely clear skies above. These conditions can develop within minutes and make school transportation genuinely dangerous.
- Polar Night (High Arctic communities): Communities like Pond Inlet and Clyde River experience 2–3 months of polar darkness with no sunrise. Closure decisions must account for visibility and safety conditions that have no equivalent anywhere in southern Canada.
- Wind — Iqaluit’s Dominant Factor: Iqaluit’s exposed position on Frobisher Bay means sustained 60–80 km/h winds are common in winter. At −25°C with 70 km/h winds, wind chill reaches approximately −47°C. Wind speed is as important as temperature for Iqaluit predictions.
Nunavut Community Climate Reference
| Community | Jan Average | Record Low | Polar Night | Avg Closures/Year |
|---|---|---|---|---|
| Iqaluit (Baffin Island) | −26.5°C | −45.6°C | ~6 weeks | 8–15 estimated |
| Rankin Inlet (Kivalliq) | −28.9°C | −50.0°C | ~6 weeks | 8–15 estimated |
| Cambridge Bay (Kitikmeot) | −31.9°C | −52.6°C | ~8 weeks | 10–18 estimated |
| Baker Lake (Kivalliq) | −32.0°C | −50.4°C | ~7 weeks | 8–15 estimated |
| Pond Inlet (High Arctic) | −30.5°C | −50.4°C | ~3 months | 10–18 estimated |
| Grise Fiord (Ellesmere) | −36.6°C | −56.0°C | ~4 months | Highest in Canada |
Nunavut School System — How Closures Are Announced
Unlike Ontario or Alberta where one board covers a large region, each Nunavut community has its own District Education Authority (DEA) that makes closure decisions independently. There is no single territorial school closure announcement — every community announces separately.
- Iqaluit DEA — Nakasuk Elementary, Aqsarniit Middle School, Inuksuk High School | Radio: CBC North Iqaluit 1230 AM, cbcnorth.ca | Announces: 7:00–8:00 AM | Community Facebook groups: fastest real-time source
- Rankin Inlet DEA — Kivalliq schools | Radio: CBC North Rankin Inlet | Community Facebook groups
- Cambridge Bay DEA (Kitikmeot) — Kiilinik High School | Radio: CBC North Cambridge Bay | Community Facebook groups
- Arviat DEA — Leo Atatsiaq School | Radio: CBC North | Community Facebook groups
- Other Nunavut communities — Each community has its own DEA. Community Facebook groups are the most reliable real-time source for closure information in smaller Nunavut communities — more reliable than websites for most communities outside Iqaluit.
Nunavut Department of Education: gov.nu.ca/education — Territorial oversight, does not direct individual community closures.

How to Use This Predictor for Nunavut
- Wind chill + wind speed together: Check both apparent temperature AND wind speed. Iqaluit’s bay exposure means wind is as significant as temperature. A −25°C day with 70 km/h winds produces wind chill of approximately −47°C.
- Check Environment Canada for blizzard warnings: At weather.gc.ca — blizzard warnings and blowing snow advisories are issued at the community level for Nunavut.
- Use community Facebook groups: For the fastest real-time closure information in Nunavut, local Facebook pages are the primary information network in most communities — faster than any website update.
- CBC North Iqaluit: For Iqaluit and eastern Nunavut — 1230 AM or cbcnorth.ca.
Frequently Asked Questions — Nunavut School Closures
How many snow days does Iqaluit get per year?
Based on available records, Iqaluit schools average approximately 8–15 closure days per year — among Canada’s highest, comparable to Newfoundland. The combination of extreme cold (January average −26.5°C) and regular Frobisher Bay blizzard events means both cold-day and blizzard triggers are active throughout the winter season.
How does Nunavut announce school closures?
Unlike southern Canada where one board covers a large region, each Nunavut community has its own District Education Authority (DEA) making independent decisions. For Iqaluit, CBC North (1230 AM / cbcnorth.ca) is the primary broadcast channel. Community Facebook groups are often the fastest real-time source in most Nunavut communities outside Iqaluit — more reliable than websites for smaller communities.
What is polar night and how does it affect Nunavut schools?
Polar night is when the sun does not rise above the horizon at all. Iqaluit experiences approximately 6 weeks of complete polar darkness from late November to mid-January. Communities further north like Pond Inlet experience nearly 3 months without a sunrise. Children travel to school in complete darkness for weeks at a time. Closure decisions must account for this in ways that have no equivalent in southern Canada.
Does snowpredictor.ca work for remote Nunavut communities?
Yes — predictions are provided for Iqaluit and several Nunavut communities using Environment Canada data with Arctic-calibrated cold and blizzard weighting. Accuracy is highest for Iqaluit where weather station coverage is most complete. For remote communities with limited nearby stations, supplement our prediction with Environment Canada community forecasts at weather.gc.ca and community Facebook groups for confirmed real-time closure information.
