About the tides at Coronation Island

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. With a mean range of about 8.3 ft, the shoreline here changes a lot between high and low water. Over the next two weeks the biggest daily range, 12.7 ft, comes today, and the smallest, 3.7 ft, on Saturday. Looking a year ahead, predictions peak at 13.4 ft on December 24 and bottom out at −3.2 ft on July 5.

Tides here are worked out from the reference station at Sitka, Baronof Island, Sitka Sound, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Affleck Canal entrance, 9 mi away, where high tide comes about 7 min later. For tidal currents, see Coronation Island - Spanish Island, between.

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