Water! You know, I always liked water, and it's a pretty decent day to swim around too. The waves are pretty much still, it's warm enough for a dip...your clothes will get soaked if you keep going, though you might not mind.
You wade out into a deeper part of the sea and stick your head under. Being totally submerged is a totally new feeling: you're weightless, and you feel the weight of the water gently push you around while you're under. You also can't breathe down there, so within a few seconds, you pop back up. You can't help but try it again, and then a third time, floating peacefully each time you go under.
You're not a terrific swimmer, so you don't go out much further, but you think it'd be cool to learn how to sometime. Gonna head back to the beach, or back to the sea stack?
