Go for it! The quickest way to the most fun is probably a snorkel rather than all of the expense and training required for scuba. All of my serious diving was free diving, snorkel without compressed air. When you strap on a tank you strap on several additional ways to kill yourself besides merely drowning, though with training it is plenty safe.
I mostly dived for lobster and halibut and then when my older son got to his teens we had a blast diving a river though we didn't live by the coast by then. All snorkel. Besides the lobster and halibut I got flounder, many kinds of fish, white sea bass, crabs and we discovered that diving for clams at high tide was so easy compared to digging them at low tide that I could sometimes pick up a limit of ten clams on two breathes of air. Freshwater pearls, lost gear from flipped canoes... Go for it!
