The currents also get more severe down near the SW end of the island. It might not be a major concern for kayaking but it sure does effect sailing. The inflow of cold water probably has a lot to do with the presence of fog. Fog can and does occur anywhere along the coast. I encountered the heaviest fog, with a military operation going on, around Halifax on my last trip.
Later in the summer is better.
