About this station
NOAA builds the predictions for Two Arm Bay, Harris Bay from the Seward, Resurrection Bay station: high tides about 1.03× the height, 10 min earlier; low tides about 0.94× the height, 5 min earlier.
Upper Cook Inlet has some of the largest tides on Earth — ranges past 30 ft, powerful rips, and bore tides on Turnagain Arm. Winter ice can push actual water levels well off the predictions.
