If you can get them, they are great in the ocean as well.
Unfortunately, I'm far away from an ocean...
I grew up on the gulf coast. I think snow should fall once or twice every year for about a day, (the average of once every ten years when I was growing up wasn't really enough), to give everyone a chance to play in it, then go away.
Now I suspect, it's going to be white until next year here, unless there's a warming spell coming up. I can just about guarantee you a white christmas, and they are far, far overrated...I miss my January garden!
That's OK, you don't have to worry about sharks then. Land sharks excluded of course.
