A seiche is a standing wave that occurs in an enclosed or partially enclosed body of water, such as a lake or bay. It is characterized by the oscillation of the water surface back and forth, similar to the movement of waves in the ocean. Seiches can be caused by various factors, including atmospheric pressure changes, seismic activity, or wind patterns. These mesmerizing water movements often create a rhythmic and calming effect, resembling the ebb and flow of tides in the sea. 🌊💦
