in the lake

Did an out and back with wifey kayaking. Total distance about three quarters of a mile.  This was our first attempt at actual navigation. I only swam into the kayak two times. I think perhaps I am trying to swim too close to the kayak. Water temperature measured 71F which seems unbelievable. Could the lake really have warmed up 11 degrees in only 6 days? It did feel a lot warmer. After getting out I was warm almost immediately. And when I got in I didn't need to flip over on my back to breathe. There were definitely some colder spots though. I'm glad I got one more lake swim in before this weekend.
