Washington Tide Charts

High tide arrives at a different time at each station. Aberdeen reaches 10.36 ft at 3:05 pm; Admiralty Head reaches 8.28 ft at 7:43 am; Ala Spit, Whidbey Island reaches 10.2 ft at 8:11 am. The table above lists the next high and the next low for all 161 Washington stations.

Barron Point, where high and low water differ by 15.3 ft today. The smallest of the 161 Washington stations with a range today is Richardson, Lopez Island at 1.2 ft. Range varies along a coast because the shape of a bay or estuary amplifies or damps the same ocean tide.

Yes, at Aberdeen, Admiralty Head, Ala Spit, Whidbey Island and 143 others. The lowest is -1.19 ft at 1:20 am. 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. 149 are mixed semidiurnal and 12 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. 58 of the 161 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.
