Currents
Deception Pass is a dramatic seascape where the tidal flow and whirlpools beneath the twin bridges connecting Fidalgo Island to Whidbey Island move quickly. During ]ebb and flood tide] current speed reaches about 8 knots (9.2 mph), flowing in opposite directions between ebb and flood. This swift current can lead to standing waves, large whirlpools, and roiling eddies. This swift current phenomenon can be viewed from the twin bridges' pedestrian walkways or from the trail leading below the larger south bridge from the parking lot on the Whidbey Island side. Boats can be seen waiting on either side of the pass for the current to stop or change direction before going through. Thrill-seeking kayakers go there during large tide changes to surf the standing waves and brave the class 2 and 3 rapid conditions.
