About the tides at Petersburg

Petersburg has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The pattern follows the reference station at Ketchikan. Petersburg sees a mean range of about 13.4 ft. Low tide can expose a wide area, and the return is fast. That is larger than most Alaska stations on this site. Over the next two weeks the biggest daily range, 19.8 ft, comes on October 11, and the smallest, 10.7 ft, on Friday.

Tides here are worked out from the reference station at Ketchikan, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Turn Point, 1 mi away. For tidal currents, see Wrangell Narrows (off Petersburg).

Predictions are based on Ketchikan.
