 The Quebecois geographer Louis-Edmond Hamelin categorized the region in his pre-north area, second of the five zones of his map of nordicity zones.The oceanic influence of the estuary of the Saint Lawrence River has a small influence on the climate of the region, making it more alike to the climate of meridional Quebec, than with "nordic" towns like La Sarre in Abitibi or Roberval, Quebec in Saguenay-Lac-Saint-Jean, located at the same latitude than the town of Matane.However, the climate of Bas-Saint-Laurent is of continental type, with a "great amplitude and no dry periods".
