Weather and tides together — the way mariners actually need it. Live wind, wave, and tide data from NOAA buoys, ships, and weather stations across Puget Sound.
Helm WX is one of the only free tools that combines real-time marine weather AND tide predictions for the same location. See conditions and tide state at a glance — no switching between apps.
No model forecasts dressed up as observations. Helm WX pulls actual real-time readings from NOAA weather stations, offshore NDBC buoys, and ships at sea reporting current conditions.

Puget Sound is one of the most complex bodies of water on the West Coast. With over 1,300 miles of shoreline, dozens of ferry routes, and tidal ranges that can exceed 14 feet at Tacoma Narrows, getting the weather and tides right isn't optional — it's safety-critical.
From the recreational boater launching from Shilshole Bay Marina to the commercial fisherman working Hood Canal, conditions on Puget Sound can shift quickly. Afternoon southerlies funnel through the narrows, fog banks roll in off the Sound in the morning, and the strong tidal currents at the Narrows can run 8+ knots at peak flood and ebb.
Helm WX aggregates live observations from NOAA stations at Seattle, Tacoma, and across the Sound, plus the offshore NDBC buoys that capture the swell coming in from the Pacific through the Strait of Juan de Fuca. Pair that with NOAA tide predictions for Elliott Bay, Tacoma Narrows, and dozens of local stations — and you have everything you need before you leave the dock.
Real-time wind, waves, and tides for Puget Sound — all in one free tool. No signup, no app, no cost.
