About the tides at Copper Harbor

Tides here are mixed. On average the two daily highs differ by 1.3 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Sitka, Baronof Island, Sitka Sound. The tide range here is very large, about 10.0 ft on average. Water can come in faster than you can walk across flats. Check the time before you go out. In the next 12 months the highest predicted tide here is 15.4 ft on December 24, and the lowest is −3.1 ft on July 5.

Copper Harbor is a subordinate station. NOAA predicts its tides by adjusting Sitka, Baronof Island, Sitka Sound: highs come about 10 min and lows about 8 min earlier than there. The nearest other station is Sulzer, 5 mi away, where high tide comes about 8 min later. For tidal currents, see Sukkwan Narrows.

Predictions are based on Sitka, Baronof Island, Sitka Sound.
