About the tides at Alva Bay

Alva Bay 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 Ketchikan, Tongass Narrows. Alva Bay sees a mean range of about 12.2 ft. Low tide can expose a wide area, and the return is fast. That is larger than most Alaska stations on this site. Looking a year ahead, predictions peak at 18.7 ft on December 24 and bottom out at −4.2 ft on July 5.

Tides here are worked out from the reference station at Ketchikan, Tongass Narrows, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Custom House Cove, 9 mi away. For tidal currents, see Point Sykes.

Predictions are based on Ketchikan, Tongass Narrows.
