Spring and Neap Tides

Spring tides produce the maximum tidal range when the earth, moon and sun are all in alignment. This produces the greatest gravitational pull on the oceans. The moon and sun gravitational pull is additive.

Neap tides produce the minimum tidal range when the moon and sun are at a right angle to each other. This alignment minimizes the gravitational pull of the moon.
