High and low tides refer to the regular rise and fall of the ocean’s waters. High tide is when water covers much of the shore after rising to its highest level. Low tide is when the water retreats to its lowest level, moving away from the shore.

What are low tides called?

Tides and Water Levels When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.

Where are the lowest tides?

Some of the smallest tidal ranges occur in the Mediterranean, Baltic, and Caribbean Seas. A point within a tidal system where the tidal range is almost zero is called an amphidromic point.
