@pndc I (along with about 100 others) spent a chunk of yesterday messing around on inflatables in a flooded quarry, although the water was 20 degrees, the differential between the water and air/direct sunlight and cooling effect of evaporation was very comfortable.. also cleared my sinuses very well jumping into the water from the top of some inflatables or the swing :) Off to the beach this afternoon, sea should be mid to high teens so ideal in 3/4mm wetsuit
