Will Moncton Schools Be Closed Tomorrow?

Moncton is New Brunswick’s largest urban centre and a city that sees some of the most varied and intense winter weather in the Maritime provinces. Its position at the head of the Bay of Fundy and near the Northumberland Strait means it lies in the path of both nor’easters tracking up the Atlantic seaboard and Gulf of St. Lawrence snowbands that can produce prolonged, heavy accumulations. Moncton averages approximately 200–230 cm of snow per year, putting it among the snowiest major cities in Atlantic Canada.

Moncton’s school closures are particularly complex because the city straddles two school districts – Anglophone South (ASD-S) and Anglophone East (ASD-E) – with French-language districts adding further complexity. Families on different sides of the same street can belong to different districts with different closure decisions on borderline weather days.

Why Moncton Gets So Much Snow

Moncton sits in a geographic sweet spot for Atlantic Canadian winter storms. The Northumberland Strait – between New Brunswick and Prince Edward Island – remains partly open well into winter and feeds moisture into developing storms. When a nor’easter approaches from the southwest, the Bay of Fundy acts as a moisture conveyor, dramatically enhancing snowfall over the region. Gulf of St. Lawrence snowbands can also produce prolonged heavy snow events when cold Arctic winds blow across the partially unfrozen gulf in November, December, and January.

The combination of these factors means Moncton regularly sees back-to-back storm systems in January and February – a week with two or three separate closure-worthy events is not unusual in an active winter. This is reflected in Moncton’s relatively high school closure frequency compared to Fredericton.

Moncton Snow Day Statistics

Moncton-area school districts average approximately 7–11 closure days per year, with heavy storm years reaching 13–15. January and February are the peak months. The coastal exposure and high snow totals make Moncton one of the more active cities in our predictor database for school closure events.

When Do Moncton Districts Announce?

Both ASD-S and ASD-E announce by 6:30 AM via their respective websites and the NB Department of Education portal. CL-104 (104.1 FM) and CBC Radio New Brunswick are the primary radio channels. The French-language districts typically announce within 30 minutes of the English districts. Twitter/X: @ASDS_NB and @ASDE_NB.

Frequently Asked Questions — Moncton Snow Days

Why does Moncton sometimes get much more snow than Fredericton on the same day?

Coastal versus inland position is the key factor. When a nor’easter tracks up the Atlantic coast or a Gulf of St. Lawrence snowband sets up, the moisture-laden precipitation hits coastal and near-coastal Moncton much harder than inland Fredericton. Moncton can receive 40 cm while Fredericton sees 10–15 cm on the same system. Both cities can be in the same province and yet have completely different school closure outcomes.

Do ASD-S and ASD-E always make the same decision?

Not always. Although they share much of the same geographic area, ASD-S covers different communities than ASD-E, and bus route conditions in one district’s territory can differ from the other’s. In major storms they almost always align; in borderline events one district may close while the other delays or stays open.
