About this station
NOAA builds the predictions for Cape Chunu from the Sweeper Cove, Kuluk Bay, Adak Island station: high tides about 1.11× the height, 104 min earlier; low tides about 1.11× the height, 114 min earlier.
Ranges shrink as you head down the chain, but the passes between islands rip hard on the change, and weather calls the shots year-round. Wind can hold water in or blow it out far beyond what the table says.
