About the tides at Roche Harbor

Tides here are mixed. On average the two daily highs differ by 1.3 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Port Townsend, Admiralty Inlet. On a typical day the water moves about 4.7 ft between high and low. That is smaller than most Washington stations on this site. Over the next two weeks the biggest daily range, 8.4 ft, comes on Wednesday, and the smallest, 3.0 ft, on Sunday. Looking a year ahead, predictions peak at 9.0 ft on December 26 and bottom out at −3.6 ft on July 4.

Tides here are worked out from the reference station at Port Townsend, Admiralty Inlet, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Hanbury Point, 2 mi away, where high tide comes about 14 min earlier. For tidal currents, see Spieden Channel, north of Limestone Point.

Predictions are based on Port Townsend, Admiralty Inlet.
