Forecast the tidal stream anywhere in the world at high resolution for dinghy and yacht racing. Watch the streams run on the map, read the tide height at any spot, and plan a beat, a start line or a passage around the flow.
Zoom into a forecast area to see the stream itself: colour for speed, arrows for direction with the rate in knots, and drifting particles tracing the flow across a course.
A full tide curve for any location in the world, computed for the conditions on the day — springs, neaps and the smaller oscillations included. Press play to watch the tide move, or scrub the timeline to a start time.
No stream data where you sail? Draw a box on the map, pick your dates, and a fresh high-resolution forecast is computed for that area in minutes. Anyone can view public forecasts free; sign up to see them all and request your own.
Buoys, beacons and lights can be overlaid on the chart to place a course. Not for navigation.
