The terminology for an incoming tide is referred to as "flood," while an outgoing tide is termed "ebb." The flood tide occurs when water levels rise as the tide comes in, typically associated with water flowing towards the shore. Conversely, during an ebb tide, the water is receding or flowing away from the shore, leading to a decrease in water level.

Understanding these terms is crucial for divers, as they directly impact tidal currents, visibility, and overall water conditions. Being able to predict and recognize the effects of these tides helps divers plan their dives safely and effectively, ensuring that they are aware of how the tides might influence their diving experience.
