rumiko, Canadians are just a tougher lot,, we figure once the ice is off the water its fine to swim in.. LOL
I actually went on a forum for Hawaii where people from California advised posters to take wetsuits to Hawaii as the water is so cold in the winter,, I fell off my chair laughing at that one... ( we always find the ocean in Hawaii warm as soup in the winter!)
Op,, I personally would not bother to bring a suit, but then I am not the type that would waste too much time at a beach when in Europe,, but, a suit does not take up much room, so really , you could just shove one into a corner of your bag if you really wanted to..
