About the tides at Thomas Bay

Expect two roughly equal high tides a day at Thomas Bay, each arriving about 50 minutes later than the day before. Thomas Bay sees a mean range of about 13.1 ft. Low tide can expose a wide area, and the return is fast. That is larger than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 15.6 ft. Over the next two weeks the biggest daily range, 19.6 ft, comes on October 11, and the smallest, 10.4 ft, on Friday.

Predictions for Thomas Bay come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here from 1923 to 2024 to set up these predictions. The nearest other station is Petersburg, 14 mi away.
