A beach getaway often symbolizes a dream vacation, featuring the allure of sunshine, warm sands, and the rhythmic sounds of the ocean. Yet, amid the pleasures of coastal havens, prioritizing safety remains paramount. While common beach hazards like rip currents and changing tides are well-known, there’s a lesser-known danger—square waves—that demands awareness.
Square waves, also referred to as “cross seas,” manifest when two sets of waves intersect, creating a distinct checkerboard pattern. This phenomenon arises from the convergence of a windsea and a swell or two separate swell systems. Though relatively uncommon, square waves are typically observed near the coastline.
For boats and swimmers, square waves pose unique risks. These waves can reach heights of up to 10 feet, altering wind patterns and complicating navigation. Although the chances of encountering square waves directly while swimming are minimal, it is essential to know how to respond if confronted with this phenomenon.
When in the water with square waves, the grid-like pattern may not be immediately apparent. However, you may experience larger swells and contend with the challenge of swimming against two distinct currents. To mitigate potential risks, it is advisable to avoid venturing too far from the shore initially. If the waves intensify or conditions worsen, promptly exit the water to ensure personal safety.
Square waves are more likely to pose threats to boats and ships situated farther from the shore. Staying in shallower waters is a safer choice during such conditions. For beachgoers, it’s prudent to remain on the shore or take a brief dip in shallow water until weather and ocean conditions improve. Always prioritize safety when enjoying the beach and ocean.
