Although they can look beautiful, crossing waves may create unpredictable water movement. This can make swimming more difficult and can also create challenging conditions for boats, especially when wind or currents are strong.
If you notice square waves, the safest choice is to stay on shore and observe them from a distance. If you are already in the water and conditions begin changing, move toward a safe exit and follow instructions from lifeguards or local authorities.
Do not assume calm-looking water is completely safe, because strong currents or changing movement can exist beneath the surface. Enjoy unusual ocean patterns from a safe location and always pay attention to local warnings.
