Why is St. John's the foggiest city in Canada?

St. John's, Newfoundland and Labrador, is often considered the foggiest city in Canada due to its unique geographic location and climate. Situated at the eastern edge of North America, it experiences frequent interactions between warm, moist air from the Atlantic Ocean and cold air from the land. This leads to the formation of fog, particularly during the summer months when temperatures rise. Additionally, the city's rugged coastline and varying topography contribute to the persistent foggy conditions.
