What It Does

TidePush calculates the best departure time for your passage by modeling tidal currents along your route. Input your waypoints, date, and boat speed, and it shows you when to leave so the current is working with you — not against you.

Built for the Pacific Northwest

The Salish Sea, Puget Sound, the San Juan and Gulf Islands — these are waters where tidal currents routinely run 3–6 knots and timing your departure can mean the difference between a pleasant cruise and a miserable slog. TidePush uses NOAA tidal current predictions to model conditions along your route hour by hour.
