About this station
NOAA builds the predictions for Chiachi Island (east side) from the KODIAK, Womens Bay station: high tides about 0.89× the height, 22 min later; low tides about 1.28× the height, 37 min later.
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.
