About this station
NOAA builds the predictions for Peterson Bay from the SAND POINT, POPOF ISLAND station: high tides about 0.83× the height, 5 min earlier; low tides about 1.05× the height, 8 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.
