About the tides at Tamgas Harbor
Tamgas Harbor has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The pattern follows the reference station at Ketchikan, Tongass Narrows. The tide range here is very large, about 12.3 ft on average. Water can come in faster than you can walk across flats. Check the time before you go out. That is larger than most Alaska stations on this site. In the next 12 months the highest predicted tide here is 18.7 ft on December 24, and the lowest is −3.9 ft on July 5.
Tamgas Harbor is a subordinate station. NOAA predicts its tides by adjusting Ketchikan, Tongass Narrows: highs come about 9 min and lows about 8 min earlier than there. The nearest other station is Metlakatla, 4 mi away, where high tide comes about 8 min later. For tidal currents, see Grass Rock, Tamgas Harbor entrance.
Predictions are based on Ketchikan, Tongass Narrows.
