Ok AKSAE, we experimented with the wetsuit change. According to the weather service it was 540 hear, but feels like 30. I have no idea what the water temp is here, but when it hit my bare skin I did yelp a bit. I wore a wetsuit, she wore jeans and T shirt and cross trainers when we jumped in the pool. We treaded for fifteen minutes then began the exchange. She dumped her shoes and it wasn't easy to get my suit off but I did. Took a bit of time to get it right side out and I had to help her into it and zip it shut, It was doable, not as hard as I expected, but we weren't fighting extreme cold temperatures, waves and currents. After ten minutes or so she said she felt a little warmer so we terminated the experiment and headed for the hot tub.
