Water is as hard as concrete from a large height.

They splash down in water because there is less chance of hitting something.

    You are talking about surface tension. The importance parameter is speed not height and "like concrete" is a drastic simplification as both behave very differently on impact.

    Notably whereas high divers have reached speeds of 60 mph the Artemis II splashed down at around 1/4 that speed a speed you too can obtain by jumping from about 10 feet up.
