Surface Currents Google Map
This Google Map from the Central and Northern California Ocean Observing System is a near real-time map of surface currents off the California coast.
The small arrows on the map depict the current speed and direction of the surface currents. The colour of the arrows shows the speed. The arrows are all selectable and, if clicked, reveal the speed and direction of currents at that location.
Links are provided in the left navigation bar to zoom to particular coastal areas. There are also links to select from hourly or daily averaged currents and to view past currents.
It is possible to turn the currents on and off under the map and to select a layer that shows the locations of HF Radar stations.
