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. 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 on October 11, and the smallest, 6.4 ft, on Friday.

Tides here are worked out from the reference station at Sitka, 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.
