Well, Thursday was our first day of NICE weather this year so far and we had some sun AND a night above 40 degrees! So with that and the increasing temps - we started at 52 deg water, moved on to 77 degree water today finally - My youngest son did go swimming on Saturday in 72 deg water. Brrrrr! but he enjoyed it - land was 77 degrees and sunny. I watched. No sun today or tomorrow, but Thursday is expected 80 deg and sunny all the way through the weekend. I expect to see 82-86 deg water and THEN I will swim.
