The same is true in Alaska. It can be 100°F in Fairbanks, and only 65°F on the coast, during the summer. Along the coast it very rarely gets more than 80°F.
Winter, on the other hand, is exactly the opposite. Fairbanks may see -60°F, while in Anchorage it may only be -20°F. Even with an average ocean temperature of +34°F, it is enough to warm the areas along the coast during the winter.
