About this station
NOAA builds the predictions for Usof Bay from the Unalaska station: high tides about 1.55× the height, 210 min earlier; low tides about 1.19× the height, 225 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.
