Eastern Newfoundland has a moderate four-season climate. The cold Labrador Current and the warm waters of the Gulf Stream meet on the Grand Banks in the North Atlantic just off the coast of Newfoundland.

With our location in the middle of the North Atlantic, one can experience extremes of ‘weather’ in a short period of time. In fact, locals will tell you that if you don’t like the weather, just “wait a minute, it will change”. Surprising to many is the fact that St. John’s has the third most temperate climate of all cities in Canada (behind Victoria and Vancouver). Summer days in the city and region are usually warm and we normally have ocean breeze. We seldom experience the humidity that goes with summer heat in central Canada or the north-eastern United States. Summer evenings can be cool; carrying a sweater is a good idea.
