1. 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.
