About this station
NOAA builds the predictions for Sand Bay, Great Sitkin Island from the Sweeper Cove, Kuluk Bay, Adak Island station: high tides about 0.97× the height, 5 min earlier; low tides about 0.97× the height, 20 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.
