Snow Day Predictor Prince Edward IslandWill school be cancelled tomorrow in Prince Edward Island?

Type your PEI postal code or "Charlottetown, Prince Edward Island" into the predictor at the top of this page. The forecast returns tomorrow’s province-wide closure probability for the Public Schools Branch. Because PSB makes one call for the whole island, the prediction applies equally from Tignish to Souris — there are no district-by-district splits.

PEI consolidated its English-language school boards into a single province-wide authority — the Public Schools Branch — to streamline administration of a small island system with roughly 20,000 students. The province is small enough that a single authority can manage every school directly. The trade-off is that closure decisions are necessarily province-wide, even when a storm is hitting Summerside harder than Souris.

Confederation Bridge is the only road link between PEI and the mainland. When sustained crosswinds force the bridge to close to high-sided vehicles and then to all traffic, supply chains, staff commutes, and emergency response across western PEI are all affected. PSB factors imminent or active bridge closures into its overnight call, especially when the bridge closure pairs with rural drifting on Prince County bus routes. The bridge’s wind status is a real input to PEI closure logic in a way no other Canadian province has.

Enter your Charlottetown postal code above. Because PSB issues a single province-wide call, the Charlottetown forecast and the province-wide forecast are the same number. Charlottetown closures are most often triggered by Northumberland Strait storms tracking up from the southwest, by freezing-rain events crossing the central island, or by extreme wind events that affect both city streets and Confederation Bridge simultaneously.

The Public Schools Branch posts closure announcements to its website, social media channels, and the EI’s major broadcasters (CBC PEI, Ocean 100, K-Rock, and others) typically between 6:00 and 7:00 am the morning of, with overnight calls posted the evening before for unambiguous major storms. Our predictor returns an advance probability the night before based on the overnight forecast, but the official call is PSB’s and is issued under its own timing.

Yes. Type any Summerside, Kensington, Tignish, or O’Leary postal code into the predictor. Because PSB closures are province-wide, the closure probability is the same across the island — but the underlying weather forecast pulls hourly data at your exact coordinates, so you’ll see accurate snowfall and wind forecasts for western PEI even when the conditions are heavier than at Charlottetown.

Yes. Commission scolaire de langue française schools — including École François-Buote in Charlottetown and the French schools in Summerside and Rustico — generally align with PSB closure calls on major weather days, though CSLF announces independently. The predictor’s overnight forecast is the same input either authority will be looking at when making its call.

Northumberland Strait storms are Atlantic low-pressure systems that track up from the U.S. Eastern Seaboard and pass through or just south of the strait between New Brunswick and PEI. They typically bring a combination of heavy snow, freezing rain, and sustained 70–100 km/h winds across the strait, which simultaneously close Confederation Bridge and pile drifts onto exposed PEI bus routes. They are the single most common closure trigger for PSB.

Three reasons. First, PEI is an island fully surrounded by open water, so storms approach from every direction rather than being filtered by inland terrain. Second, rural bus routes cross long stretches of exposed coastal road that drift shut at wind speeds Nova Scotia and New Brunswick inland routes handle easily. Third, PSB makes one province-wide call rather than letting central districts stay open while rural districts close — so when any part of the island is unsafe, the whole island closes. The combined effect is a higher closure frequency per centimetre of snowfall than mainland Maritime authorities.
