About this station
NOAA builds the predictions for Cape Mordvinof from the Unalaska station: high tides about 1.73× the height, 26 min later; low tides about 1.36× the height, 19 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.
