You might think Moncton’s climate to be maritime-like, because it’s near the Bay of Fundy and the Northumberland Strait. However the climate is mostly continental, especially during the summer and winter seasons.

Winter days in Moncton are cold - but they’re usually sunny! There are several cold snaps throughout the winter with temperatures falling to the range of 5 to -13F/ -15 to -25C. Major snowfalls often result from nor'easter ocean storms moving up the east coast of North America from the southern United States.

Large amounts of precipitation can result from the counterclockwise rotation of these storms picking up moisture from the Atlantic Ocean and dumping it on southeastern New Brunswick as the storms pass by to the south and east. First snowfalls take place by mid-November. Spring doesn’t come early here, as it takes until the end of March that daytime temps are above freezing.

Summers are usually comfortable and not too hot, with daytime highs usually reaching the mid to high 68 F/20 C. Temperatures in the low to mid 80’s F/30's C occur 6-10 times per year. Rainfall is modest and periods of drought are not uncommon.
