Hawaii Tide Charts

High tide arrives at a different time at each station. East Island, French Frigate Shoals reaches 1.56 ft at 5:47 am; Ford Island, Pearl Harbor reaches 2.23 ft at 5:55 am; Haleiwa, Waialua Bay reaches 1.71 ft at 4:40 am. The table above lists the next high and the next low for all 32 Hawaii stations.

Hana, where high and low water differ by 2.6 ft today. The smallest of the 32 Hawaii stations with a range today is Laysan Island at 1.0 ft. Range varies along a coast because the shape of a bay or estuary amplifies or damps the same ocean tide.

Yes, at Hana, Kahului, Makena and 2 others. The lowest is -0.06 ft at 9:10 pm. A minus tide is water below mean lower low water, the zero point for US predictions, and it exposes ground that is normally covered.

Not all alike. 27 are mixed semidiurnal and 5 are diurnal. Each station page classifies itself from its own predictions rather than from a regional rule, because the pattern changes along a single coast.

NOAA states roughly ten minutes on timing and half a foot on height for a reference station in ordinary weather. 11 of the 32 stations here are reference stations; the rest are subordinate, with times and heights derived from one by a published offset, so expect a little more spread. Weather is the bigger factor either way. A storm surge or a strong onshore wind can raise real water well above the prediction, which is astronomy only.
