Dry Land Issues

Once you’re out of the water, there are still dangers to be found from ocean-going. Lightning is a particular danger because of the wide expanse of open land found at most beaches. About 60 people per year are killed by lightning, although not all of them at the beach. If a storm approaches, head for a building, shelter or shed. Avoid soft-top vehicles or convertibles, and it is suggested that those wishing to return to the beach should wait at least a half-hour after the last thunder clap.

Less likely is a tsunami, or tidal wave. This is caused by the displacement of water on the sea floor, usually because of volcanic activity, earthquakes or other major disturbances. The warning signs include the sudden retreat of water beyond the usual shore breaks, leaving a vast expanse of wet beach that water normally would cover. This is followed by a wall of water that’s extremely fast and may be several feet high. The only solution is to head for higher ground and shelter if you believe one is about to strike.

Animals in the Sea

Of course, the sea harbors thousands of aquatic species, including some that have been known to attack humans. The most frequent are shark attacks, which seem to occur every summer in certain locations.

Contrary to popular belief, most shark attacks don’t occur in deep water but can happen relatively near shore, most frequently between sandbars, where sharks can get trapped temporarily during low tide. While uncommon, they are a consideration if you go beyond the wading areas of the ocean.
