high tide

The tide when it is at its highest level at a particular time and place. The highest tides reached under normal meteorological conditions (the spring tides ) take place when the Moon and Sun are directly aligned with respect to Earth. High tides are less extreme (the neap tides ) when the Moon and Sun are at right angles. Storms and other meteorological conditions can greatly affect the height of the tides as well.
