Growing up, I was told to exit the pool when there was rain. It makes sense- relatively small volume of water + significant voltage can conclude pool day pretty quick.
But what about the ocean? If water conducts electricity, how does lightning not spread to every beach all the time?

In a sense it kind of does. But the amount of current through any given bit of water is negligible because of how much there is. So if you are in the water any distance away from the strike, the voltage difference between one side of your body and the other is really small so there’s no shock. The current just flows around you.
