Chaleur Bay

Chaleur Bay (in French, Baie des Chaleurs) - also known informally in English as Bay of Chaleur due to the influence of its French translation - is an arm of the Gulf of Saint Lawrence located between Quebec and New Brunswick.

The name of the bay is attributed to explorer Jacques Cartier (Baie des Chaleurs). It translates into English as "bay of warmth" or "bay of torrid weather".

Chaleur Bay opens to the east with its southern shore formed by the north shore of New Brunswick. The northern shore is formed by the south shore of the Gaspé Peninsula. The bay measures approximately 50 km (27 nmi) in width at its widest point between Bathurst and New Carlisle. The western end of the bay transitions into the estuary of the Restigouche River at Dalhousie, New Brunswick.

The mouth of the bay is delineated by a line running from "Haut-fond Leander" near Grande-Rivière, Quebec in the north and the "Miscou Shoals" near Miscou Island, New Brunswick in the south.

Canadian Hydrographic Service chart number 4486 is the bathymetric navigational data repository for the area.

The shores of Chaleur Bay include numerous beaches, particularly on the southern shore. Many rivers also form barachois or barrier beaches. Incorrectly claimed by locals as the world's second longest natural sand bar, the Eel River Bar, is a barrier beach located at the mouth of the Eel River immediately west of the village of Charlo, New Brunswick. This sand bar is unique not only because it has fresh water on one side and salt water on the next, but because it is home to the endangered piping plover.
