About this station
Scotch Cap is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
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.
