Not just water, but cold water.
Water because they need it's support to move.
Cold because of their mass plus their insulation means that would overheat (to death) if out of water for very long.
They do not have legs to walk on land. On top of that, since most whales hunt by filtering out things while swimming. They are best adapted to be in the water.

Whales need the water. In the the water, whales are weightless. On land, whales weigh tons. If a whale is on land too long, they are crushed by their own weight. beached whales need water poured over them because they live in the ocean, so they are always wet, but when beached, their skin will start to dry out, which can kill them
