Will Sherbrooke Schools Be Closed Tomorrow?

Sherbrooke is Quebec’s sixth-largest city and the urban core of the Eastern Townships (Cantons-de-l’Est). Located in the Appalachian foothills approximately 150 km southeast of Montreal, Sherbrooke sits in a river valley where the Magog and Saint-François rivers converge. The city’s Appalachian surroundings and inland valley position give it a colder, snowier climate than Montreal, with significant exposure to nor’easters that track inland from the New England coast.

Sherbrooke averages approximately 260–290 cm of snow per year – substantially more than Montreal, reflecting its interior Appalachian position and greater elevation. The city and surrounding Eastern Townships are served by a French-language centre de services scolaire and an English-language school board, making Sherbrooke one of Quebec’s bilingual school communities.

Sherbrooke’s Appalachian Winter Climate

The Appalachian foothills of the Eastern Townships create a winter climate that is more intense than the St. Lawrence lowlands around Montreal. When nor’easters track inland from the New England states, the Appalachian terrain forces the systems upward and enhances precipitation over the Eastern Townships. Sherbrooke, sitting in a valley surrounded by these foothills, receives both the direct storm precipitation and orographic enhancement from the surrounding terrain.

The Saint-François River valley also acts as a channeling feature for cold air drainage — overnight temperatures in Sherbrooke can be 3–5°C colder than surrounding areas, which means precipitation that might fall as cold rain in Montreal more often arrives as snow in Sherbrooke. This temperature difference is reflected in Sherbrooke’s significantly higher snowfall totals compared to the Montreal metropolitan area.

Sherbrooke Snow Day Statistics

Sherbrooke-area school authorities average approximately 7–11 school closure days per year. Major nor’easter events that produce 25–50 cm in 24 hours are the primary closure driver. These storms affect the Eastern Townships more severely than the St. Lawrence lowlands and occur 3–6 times per winter. January and February are the peak months, with March nor’easters also common in the Appalachian region.

When Do Sherbrooke School Authorities Announce?

By 6:30 AM via their respective websites. CBC Radio-Canada Estrie and Radio Centre-Ville 107.7 FM are the primary media channels. The CSSRS and ETSB make independent decisions, though they typically align for major events. Quebec’s overall school closure protocol requires boards to consult with transportation services before 6:00 AM on storm mornings.

Frequently Asked Questions – Sherbrooke Snow Days

Why does Sherbrooke get more snow than Montreal?

Sherbrooke’s Appalachian foothills position means it receives orographic enhancement that Montreal, in the flat St. Lawrence lowlands, does not. When storms move northeast from New England, the Appalachian terrain in the Eastern Townships forces air upward, cooling it further and enhancing snowfall significantly. Sherbrooke is also further inland and at higher elevation, where temperatures are colder and precipitation is more consistently snow rather than rain or freezing rain.

Do CSSRS and ETSB close on the same days?

Usually for major storms, yes. Both authorities serve the same geographic area and face the same weather conditions. However, their transportation networks serve different student populations and route conditions can vary slightly. For borderline events, one may close while the other implements a delayed start or stays open — always verify with your specific board’s website.
