I don't know where you are, but would wetsuit help to extend the time you can swim in the open waters? Obviously, I'm just assuming you're not doing that already... :)
I don't know about you, but I'm particularly motivated by endurance activities in the cold. The mental aspect of accepting the cold's effect on you is often more interesting than the motoric process of running or swimming.
