New Brunswick Climate
Two Personalities

The coastal portion of the New Brunswick climate can be considered part of the Atlantic Climate Region of Canada.

However, the climatic landscape rapidly diversifies inland, as other geographical situations exert their influence!

Its northern coast is under the influence of the western Gulf of St. Lawrence cool waters.

But the southeastern coast, and the southern coastal areas are under the influence of the somewhat warmer waters of the Northumberland Strait, and the Bay of Fundy, respectively.

No wonder the beaches are so popular with summer vacationers! It's the New Brunswick weather at its best!

However, the interior has more of the characteristics of the "Continental" Southeastern Climate of Canada.

Much of New Brunswick's northwestern hilly terrain is more than 300 meters above sea level, rendering it different from the St. Lawrence valley, and lower Great Lakes regions of southern Quebec and Ontario, respectively.

Temperatures

Summer temperatures in the interior can be as high as those of southern Ontario and Quebec. Mean July temperature is around 20C, but extreme maximum temperatures nudging 40C are often experienced in the valleys.

On the other hand, the southeastern and southern coastal areas have mean July and August temperatures in the 17C to 18C range.

Mean January temperatures range from -13C in the northwest interior to near -8C in southeastern coastal areas.

Precipitation

New Brunswick has mean annual precipitation ranging from around 1000mm in the northwest, to more than 1200mm on the north shore of the Bay of Fundy. The heaviest precipitation normally occurs during the late autumn and early winter months. Some 250cm to 300cm of snow generally fall on the northwestern half, while 175cm to 225cm falls on the southeastern half.

Fog is noteworthy on the coastal areas of the Bay of Fundy, especially in July. Some sectors report nearly 100 days with fog per year. However, fog often clears by midday.

In Short

With its continental interior, and its lengthy coastal sections, New Brunswick climate conditions can suit most tastes!

Stay tuned, and keep a sharp weather watch!
