About the tides at Port Madison
Tides here are mixed. On average the two daily highs differ by 2.3 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Seattle, Puget Sound. With a mean range of about 7.6 ft, the shoreline here changes a lot between high and low water. Over the next two weeks the biggest daily range, 13.4 ft, comes today, and the smallest, 3.9 ft, on Thursday. Looking a year ahead, predictions peak at 13.1 ft on January 25 and bottom out at −3.9 ft on December 24.
Tides here are worked out from the reference station at Seattle, Puget Sound, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Port Jefferson, 4 mi away, where high tide comes about 12 min earlier. For tidal currents, see Agate Passage, north end.
Predictions are based on Seattle, Puget Sound.
