Stratford Snow Day Predictor – Avon Maitland DSB and Huron-Perth Catholic
Will Tomorrow Be a Snow Day?
Canada's most accurate snow day predictor
Stratford sits in Perth County in Southwestern Ontario, well within reach of Lake Huron lake-effect snow. The city averages approximately 180–220 cm of snow per year and is served by the Avon Maitland District School Board (AMDSB). Perth County’s flat, open farmland and the board’s extensive rural bus network make both Lake Huron squalls and severe drifting frequent closure triggers – Stratford schools close more often than the Ontario average.
Will Stratford schools be closed tomorrow? Enter your city in the predictor above for tonight’s closure probability, updated hourly from Environment Canada data. Always confirm with your school board’s official channels before making plans.

Stratford Snow Day Triggers – What Closes Schools Here
Stratford’s closures are driven by:
- Lake Huron lake-effect (primary driver): Stratford sits directly downwind of Lake Huron for the west and northwest winds that produce lake-effect snow. Squalls can deliver 20–40 cm to Perth County while areas east see little.
- Severe Perth County drifting: The flat, exposed farmland of Perth and Huron counties produces some of Ontario’s worst blowing and drifting snow, regularly closing rural bus routes.
- Snow squall warnings: The Huron-Perth area is one of the most frequently issued snow squall warning zones in Ontario.
How Often Do Stratford Schools Close?
The Avon Maitland DSB averages approximately 6–10 full closure days per year – above the Ontario average – driven by Lake Huron lake-effect and severe Perth-Huron drifting. Rural bus cancellations are very frequent. November through March are peak months.

Frequently Asked Questions – Stratford Snow Days
Which school board and bus zone does the Stratford predictor track?

Why does the Stratford predictor spike when city roads look fine?
Which school board and bus zone does the Stratford predictor track?
The predictor tracks data for the Avon Maitland District School Board (AMDSB) and the Huron-Perth Catholic District School Board. For transportation, Stratford is located within Zone 1 (Perth South) of the Huron Perth Student Transportation Services (HPSTS).
How much snow is required to trigger a high percentage on the Stratford predictor?
Local plow crews are highly experienced, so a normal 10 cm snowfall rarely causes a cancellation. The predictor’s algorithm spikes significantly only when a weather warning forecasts 15 to 20 cm of rapid accumulation, or when high winds create heavy blowing snow and zero-visibility conditions on rural regional highways like Highway 7 and 8.
If the Stratford predictor hits 100% and buses are called off, do schools close?
No, schools almost always stay open for walking students and staff even when buses are cancelled. However, a maximum predictor percentage helps parents prepare for “inclement weather days” where regular curriculum lessons are paused, and all scheduled tests, quizzes, or exams are postponed
What time is the Stratford snow day predictor most accurate?
The morning check between 5:00 AM and 5:30 AM is the most accurate window. While checking at 9:00 PM the night before provides a helpful baseline estimate, volatile lake-effect snow bands coming off Lake Huron can shift rapidly overnight, requiring final morning radar updates right before the official HPSTS announcement at 6:30 AM
