About the tides at Kupreanof Harbor
Kupreanof Harbor has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at KODIAK, Womens Bay. With a mean range of about 5.3 ft, the shoreline here changes a lot between high and low water. That is smaller than most Alaska stations on this site. Over the next two weeks the biggest daily range, 9.7 ft, comes on October 11, and the smallest, 5.8 ft, on Tuesday.
Tides here are worked out from the reference station at KODIAK, Womens Bay, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Ivanof Bay, 9 mi away, where high tide comes about 13 min later.
Predictions are based on KODIAK, Womens Bay.
