The Pacific is wide and deep, so its tide is a wave that takes about half a day to run round each basin. In the North Pacific it turns anticlockwise round a point northeast of Hawaii. South of the equator it turns mostly clockwise.
Out in the open ocean the tide is small: at Hawaii the sea rises and falls less than a metre. Near Tahiti the Moon's tide almost vanishes, and what remains is the Sun's: high water comes close to noon and midnight every day.
On the edges it grows. Shallow shelves and long bays build ranges of 8 metres and more off the west coast of Korea, in northwest Australia, in Cook Inlet in Alaska and at the head of the Gulf of California.
