What Makes the Ocean Feel So Cold?

The ocean feels so cold because water takes more energy to warm up than air does. Think of it like a big, slow heater, when you jump in, the water quickly steals your body’s warmth. The deeper you go, the colder it gets because there's less sunlight to heat things up.
