Winter Storm Warnings in Moncton, New Brunswick
Moncton sits in a corridor of southeastern New Brunswick that funnels cold Arctic air and Atlantic moisture into some of the most persistent winter weather in the Maritimes. Analyzing 13 years of data from 2012 through 2024, the city averages 217.5 cm (85.6 inches) of snowfall annually — a substantial burden that shapes how residents, road crews, and emergency planners approach every cold-weather season.
The heaviest snow tends to pile up during February, January, and December, when average winter overnight lows sink to around -9.9 °C (14.2 °F). At those temperatures, falling snow stays dry and drifts easily, which can reduce visibility and close roads far faster than raw accumulation totals alone would suggest. Over the study period, Moncton experienced roughly 2.6 heavy-snow days per year — often enough that locals treat them as a near-certain feature of winter rather than a rarity.
A winter storm warning for this area signals that conditions are expected to become dangerous — typically through rapid accumulation, strong winds, or both — requiring people to reconsider travel and take protective precautions. It is worth noting that warning thresholds are not uniform across Canada; the snowfall amounts or wind speeds needed to trigger a warning in Moncton may differ from those used in milder or more inland regions, so always rely on your local forecast rather than assuming a universal standard applies.
