Shilshole Bay Marina is home to over 1,400 boats and is the primary launch point for Seattle boaters heading into Puget Sound, the Strait of Juan de Fuca, and ultimately the San Juan Islands. The marina sits just north of Golden Gardens Park, with a direct fetch across the Sound toward the Olympic Peninsula.
Conditions at Shilshole can be deceiving. The bay itself is often calm when the northerlies are howling off Admiralty Inlet, and afternoon sea breezes from the southwest can build quickly between Bainbridge Island and the Seattle waterfront. The NOAA buoy near the entrance to Puget Sound, combined with the Seattle tide gauge, gives you a real picture before you untie.
Planning a run north to the islands? Check the tidal window through Admiralty Inlet — fighting a 2-knot ebb while bucking a 15-knot chop is no fun. Helm WX puts both pieces of data right next to each other so the planning is straightforward.
