Currents

Ocean currents map

Offshore currents drawn as living streaks, coloured by temperature, at the same detail whether you are looking at a whole ocean or a single reef. Near the coast the sharper 9 km ocean model takes over from the satellite field, because that is where the satellite goes blind.

  • Satellite-observed current, model forecast out seven days
  • Streak length is speed; tap anywhere for knots and direction
  • Radar-measured currents where we have them (US coasts today)

How it works

Ocean current maps are usually either a coarse satellite picture or a single model run with no sign of how old it is. Gannet View draws both, says which one you are looking at, and states the date on the layer.

Offshore, the current comes from satellite-derived surface currents. Close to the coast, where satellites lose their grip, the sharper 9 km ocean model is blended in. Tap anywhere for speed in your own units and the direction the water is going.

Tap anywhere to see which way the water is moving and how fast. Where high-frequency radar exists it is used as a measured reference.
