About this station
NOAA builds the predictions for Day Harbor from the Seward, Resurrection Bay station: high tides about the same height, 2 min earlier; low tides about the same height, at the same time.
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.
