We swam Sunday, and I put the solar cover on every night this week, but lows in the 40's and highs in the 70's have really cooled it off. When I put my arm in to test this morning, the water was cold. I'll probably pull the solar cover off the reel tomorrow to get it dry. Still a long way from closing temperature, but low air temps and cold water just don't do much for me.
I hope to get my solar installed in the spring before opening so I can stretch the season a little more next year. Two years ago we swam in October, but Saturday the high is going to be in the 60's.
