The term ‘king tide’ is a non-scientific term that refers to the highest winter tides that occur each year. These extreme high tides occur when the moon’s orbit comes closest to the earth, the earth’s orbit is closest to the sun, and the sun, moon and earth are in direct alignment, thereby increasing their gravitational influence on the tides. These tidal events are also known as perigean spring tides.

The Oregon King Tides Project is co-coordinated by the Oregon Coastal Management Program and the CoastWatch program of the Oregon Shores Conservation Coalition.
