Explanation – Swell waves are generated by distant weather systems, and they can travel across vast oceanic distances without being significantly affected by local winds or currents. They have long wavelengths and periods, which allow them to maintain their energy as they travel. Unlike wind waves, which come from local winds and are shorter, steeper, and less organized, swell waves have a longer time and wavelength, making them stronger and able to move far. They impact the erosion of the beach, the flora and fauna inhabiting the beach, and recreational activities such as surfing and boating.
