Sea Water Velocity

The speed and direction of ocean currents at various depths.

For reference, average circulation in Hawaiʻi is roughly from east to west, intensifies southward, and decreases with depth. Driven by wind, surface currents yield more complicated flow patterns and may exhibit vigorous eddies or swirls on the lee (west) of the islands. Another factor to consider nearshore are tidal currents, which tend to be aligned with the shoreline and are often stronger than the large-scale circulation.
