TidalMap
Tides, river flow and dam releases at your spot
Know When to Launch
The tide at your inlet, the flow on your river and the release from the dam above it, live on one map.
What TidalMap is
TidalMap is a map app for anglers and boaters, on the web, iPhone and Android. It puts the tide, the river and the dam on one chart and answers for the spot you are looking at, not the whole county. It reads more than 3,000 NOAA tide stations on every US coast, USGS river gauges in all 50 states and Puerto Rico, all 43 TVA dams plus Army Corps projects, and more than 3,600 weather stations from offshore buoys to inland airports. It is made on North Carolina's Crystal Coast.
The water moves forward in time, and so does the map. Rain on the Blue Ridge Tuesday. The gauge at the gap rises Wednesday. TVA changes generation Thursday, and the tailwater you wade answers within hours. Down on the coast, the tide decides which two hours you can reach the flat.
Tide times by state
Today's highs and lows, live water levels and the month's flood tides for every NOAA station.
River flow
Live flow and stage at USGS gauges, set against that gauge's normal for the month.
Dam releases
TVA generation for today and tomorrow, and the latest observed release at Army Corps dams.
Start close to home: North Carolina tides, Tennessee rivers, South Holston Dam and Fontana Dam. See where every number comes from, read the Field Notes, or get the app.
Live Tide Predictions
NOAA CO-OPS predicted and observed tides for every station on the US coast. Interactive charts, tide calendars, and live gauge levels.
Wind, Waves & Water Temp
Wind, air and water temps, wave height and pressure from buoys, shore stations, tide stations and airports. Picks the nearest station on the water before it settles for a runway.
Forecast Overlays
Wind, rain and cloud cover, swell height and sea surface temperature. Scrub forward up to 72 hours and watch the wind at your launch hour by hour.
Solunar & Moon
Moon phase, illumination, and tidal coefficient. Major and minor solunar feeding periods with a gravitational force sparkline.
Waypoints & Trips
Long-press to save a spot with auto-captured conditions. Record GPS tracks of your trips. Condition tags for time-travel planning.
Nautical Charts
NOAA raster nautical charts, satellite imagery, OpenSeaMap marks, and multibeam bathymetry layers with adjustable opacity.
