Introduction

---

The climate of New Brunswick, a province of eastern Canada, is continental, with freezing, snowy winters and pleasantly warm summers. Although New Brunswick is a maritime province, facing the sea on two sides (the Gulf of Saint Lawrence to the east and the Bay of Fundy to the south), winter is very cold because air masses generally come from the interior, moreover, a cold current flows in the sea.
During cold spells, the temperature can drop to -30 °C (-22 °F) or even below. In January 1994, it dropped to -35 °C (-31 °F) in Bathurst, and to -31 °C (-24 °F) in Fredericton and Moncton. In summer, hot days, with highs of 30/32 °C (86/90 °F), are possible but quite rare. In 2001, the temperature reached 34 °C (93 °F) in Bathurst, and 35 °C (95 °F) in Fredericton and Moncton.

Precipitation is fairly well distributed throughout the year, and hovers around 1,000/1,100 millimeters (40/43 inches) per year in the center-north, while it reaches 1,200/1,300 mm (47/51 in) on the southern coast. Snowfalls are abundant: generally, 2-3 meters (6.5/10 feet) of snow fall per year, although in Grand Maran, the southernmost island, it drops below 2 meters (6.5 ft).
The province is fairly flat, although in the interior there are hills, the highest point of which is Mount Carleton, 820 meters (2,690 feet) high.
In winter, the sea, in the areas where it is most closed (Chaleur Bay, Northumberland Strait) can be frozen.
From mid-July to early September, whales can be observed in the Bay of Fundy.
In the south, in the bay of Fundy, there are the highest tides in the world, as many as 12 meters (39 feet) high.
