About this station
NOAA builds the predictions for Chernofski Harbor from the Unalaska station: high tides about the same height, 10 min earlier; low tides about 1.10× the height, 29 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.
