The Narrows to Peekskill. Fetch, wind and tide set the chop. NOAA shoreline, OpenStreetMap base map.
Colour is wave height at each spot for the wind and tide you set. Orange streaks are wind, blue streaks are the tidal current. Streak speed is for feel, not to scale.

Pick an hour on the chart to load its forecast wind and tide, or set your own: moving the dial or a slider switches to manual. Drag the dial to turn the wind. Ring colour shows the wave height each wind direction would give at the selected point. Tap a marker or chip to select it. Launch markers sit in open water about 300 m off the piers; the teal one is the forecast tool's spot. Current directions are NOAA station NYH1928 (Pier 92). Estimates come from a simple fetch and current model, so check them against what you see on the water.
