Midland Snow Day Predictor – Simcoe County DSB and Simcoe Muskoka Catholic
Will Tomorrow Be a Snow Day?
Canada's most accurate snow day predictor
Midland sits on the southeastern shore of Georgian Bay in northern Simcoe County, directly exposed to lake-effect snow. The town averages approximately 280-320 cm of snow per year and shares the Simcoe County District School Board (SCDSB) with Barrie and the rest of the county. Midland’s Georgian Bay location and the surrounding rural Tiny and Tay townships make both lake-effect snowfall and rural bus route conditions frequent closure triggers.

Midland Snow Day Triggers – What Closes Schools Here
Midland’s closures are driven by Georgian Bay:
- Georgian Bay lake-effect (primary driver): Midland’s southeastern bay location places it directly in the path of lake-effect snowbands. Events regularly deliver 25–45 cm to the Midland-Penetanguishene area.
- Rural township roads: The surrounding Tiny and Tay townships have extensive rural bus routes that close for drifting and heavy accumulation.
- Multi-day accumulation: Persistent lake-effect flow can produce back-to-back closure days in the Midland area.
How Often Do Midland Schools Close?
As part of the SCDSB, Midland schools close approximately 7–11 days per year, reflecting its direct Georgian Bay exposure. Rural Tiny and Tay township routes add frequent bus cancellations. November through March are peak months.

Frequently Asked Questions – Midland Snow Days
Which school board and bus zone does the Midland predictor track?
The predictor calculates data for the Simcoe County District School Board (SCDSB) and the Simcoe County Catholic District School Board. For transportation routing, Midland is located directly inside the North Zone (Zone 1) of the Simcoe County Student Transportation Consortium (SCSTC).
Why does the Midland predictor spike when town streets are clear and salted?
Midland shares its North Zone weather designation with expansive, open rural municipalities like Tiny, Tay, and Severn townships. The predictor calculates risk for the whole zone, meaning that blinding snow squalls or heavy ice accumulation on rural side roads outside town will cancel Midland’s school buses even if downtown streets are clear.
How much snow triggers a high cancellation percentage on the Midland predictor?
Standard snowfall rarely triggers a cancellation because local plow crews are highly efficient. The predictor’s algorithm spikes significantly when a weather warning forecasts 15 to 20 cm of rapid accumulation, or when high winds create heavy blowing snow and zero-visibility conditions across the open fields of the surrounding townships
If the Midland 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 or assignments are postponed.
When is the best time to check the Midland predictor for the highest accuracy?
The morning check between 5:00 AM and 5:30 AM is the most accurate. While checking at 9:00 PM the night before provides a helpful baseline estimate, lake-effect snow bands coming off Georgian Bay are incredibly unpredictable and can shift overnight, requiring final morning radar updates right before the official SCSTC announcement at 6:00 AM.
