Spring tides
When the Sun, the Moon and The Earth, all are arranged in straight line.Due to gravitational pull of Sun and Moon these tides are occurred.These tides occur twice in a lunar month regardless to any season.
Whereas Lunar tide is due to gravitational pull of Moon on the the sea of the earth planet.
Low tide: These are the tides formed in the sea when the sea is at the lowest level.
Neap tides occur when the Sun and the Moon form right angles with the Earth
So, the given figure represent Spring tide.
