The tides of the ocean are at their highest when the earth, moon, and sun are in a line.
The period of the tide cycle when there is maximum tidal movement. Spring tides are generally referred to as those during which water movement exceeds three or four metres between high and low tide and such periods are often referred to as springs.
Fortnightly tides occurring when the vertical tidal range is maximal.
Higher than normal high tides observed every 2 weeks when the earth and moon align.
Spring tides are especially strong tides. They occur when the Earth, the sun, and the Moon are in a line. The gravitational forces of the Moon and the sun both contribute to the tides. Spring tides occur during the full moon and the new moon.
Extreme high and low tides that occur about twice a month, with the full and new moons
Tides which have the greatest range between low tide and high tide.
Spring tides are the biggest tidal range and occur twice a lunar month. They occur at the new and full moon i.e., when the moon and sun are positioned in opposition to each other.
