Windsor Ontario Snow Day Predictor
Canada's most accurate snow day predictor
Will Windsor Schools Be Closed Tomorrow?
Windsor, Ontario’s southernmost major city, has a milder climate than virtually every other Canadian city — but winter still brings real challenges. Windsor averages approximately 90–110 cm of snow per year, significantly less than other Ontario cities, but ice storms and freezing rain are a more significant risk than in most of Ontario. Windsor’s position between Lake St. Clair (north) and Lake Erie (south) creates occasional lake-effect snow events, and the city’s flat topography means blowing snow on exposed county roads is a major factor in closure decisions for the Greater Essex County DSB’s rural routes.

Windsor Snow Day History
GECDSB averages approximately 2–4 closure days per year — among the lowest in Ontario, reflecting Windsor’s milder climate. When closures do occur, they are most often driven by ice storms or freezing rain rather than pure snowfall. Leamington and Essex County’s flat agricultural routes are more exposed to blowing snow than Windsor itself.

Frequently Asked Questions — Windsor Snow Days
Why does Windsor get fewer snow days than other Ontario cities?
Windsor has Canada’s mildest major-city winter climate. Its southernmost Ontario position means it frequently receives precipitation as rain when other Ontario cities get snow, temperatures are milder on average, and even winter storms are often less severe than elsewhere in the province. When closures do occur, freezing rain is usually the cause rather than snow volume.
