Will St. John’s Schools Have a Storm Day Tomorrow?
In Newfoundland, school closures are called “storm days” — and St. John’s earns more of them than virtually any other city in Canada. The capital of Newfoundland and Labrador sits on the northeastern tip of the Avalon Peninsula, directly exposed to the full force of Atlantic Ocean weather systems. St. John’s averages approximately 325–360 cm of snow per year — the highest of any major Canadian city — and experiences an average of 10–15 storm day closures annually through the NLESD.
The city’s position at the very northeastern point of the island means it receives direct hits from nor’easters that have tracked up the entire Atlantic seaboard and strengthened over warm Gulf Stream waters. Some of North America’s most intense winter storms make landfall at or near St. John’s. Combined with the city’s hilly terrain and narrow historic streets, even moderate storms by Newfoundland standards can be genuinely disruptive.

Why St. John’s Gets So Many Storm Days
Three factors make St. John’s Canada’s storm day capital: First, location — the Avalon Peninsula juts into the northwest Atlantic directly in the path of every nor’easter, extratropical cyclone, and Atlantic winter system that tracks north from the eastern US seaboard. Second, ocean temperature contrast — the nearby meeting of the cold Labrador Current and warm Gulf Stream creates intense atmospheric instability that feeds and strengthens winter storms as they approach. Third, terrain — St. John’s built environment of narrow, hilly streets, and Signal Hill geography create local wind enhancement and snow accumulation that makes the city difficult to clear quickly.
St. John’s Storm Day History
NLESD closures in the St. John’s region average 10–15 per year. In major storm years, this can reach 20+. The city has experienced some of the most extreme individual storm events in Canadian history, including the January 2020 Snowmageddon (more than 90 cm fell in approximately 24 hours, burying cars to their rooftops and requiring a state of emergency).
When Does NLESD Announce?
By 6:30–7:00 AM via nlesd.ca and CBC Radio NL 640 AM. In extreme events, advance closures are sometimes announced the night before. Twitter/X: @NLESD.

Frequently Asked Questions — St. John’s Storm Days
Why are school closures called “storm days” in Newfoundland?
The term “storm day” is unique to Newfoundland and reflects the province’s culture of severe weather events. In Newfoundland, closures are typically caused by full Atlantic storm systems — blizzard conditions, high winds, heavy snow — rather than ordinary snowfall. The word “storm” better captures the nature of events that close schools there than the more generic “snow day.
How much snow can St. John’s get in one storm?
Major nor’easters have delivered 60–90+ cm of snow to St. John’s in single events. The January 2020 blizzard produced approximately 90 cm in roughly 24 hours, one of the largest single-storm totals ever recorded in a major Canadian city. These are extreme events; typical closure-level storms deliver 20–40 cm.
