Lowest Tides of the Year on Oregon Coast in May

Lowest Tides of the Year on Oregon Coast in May: "May 17 and 18 will be the lowest minus tides, clocking in at more than minus two, around 7:20 in the morning, according to the Hatfield Marine Science Center. In fact, Bill Hanshumaker, public information officer with the center, said to look for 2.5-foot minus tides on those days.

Tides, Hanshumaker said, are brought about by the moon tugging at the oceans. Gravity makes a bulge in the bodies of water, which creates the high tide. On the opposite side of the Earth there is another high tide, because of the inertia of the ocean water, and because the Earth is being pulled towards the moon but the ocean water lags behind. This creates another “bulge” on the other side."
