Currents and Tides. Ocean Currents. Ocean currents are a continuous directed flow of ocean water capable of traveling thousands of kilometers. Surface currents move water at the surface of the ocean, while submarine river currents flow deep below. Ocean currents can significantly influence the climate of coastal areas.

The California current in the Hawaiian Islands results in a climate much cooler than other tropical latitudes.
