The foggiest place in the world is the Grand Banks off the island of Newfoundland, Canada, with over 200 foggy days each year.

Fog is frequent here as the Grand Banks is the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. The cold Labrador Current runs over the Grand Banks, and when warm air passes over this water, a dense fog forms.

The fog, shallow waters and drifting icebergs make navigation difficult in this region. About 150 km south of the Grand Banks lies the shipwreck of the Titanic.

The foggiest land areas in the world are Point Reyes, California, and Argentia, Newfoundland and Labrador, both with around 200 foggy days a year.
