How fast are surface currents?

Surface currents typically move at speeds ranging from 0.1 to 3 meters per second (about 0.2 to 6.7 miles per hour), depending on factors such as wind strength and water density. These currents are primarily driven by wind patterns and the Earth's rotation, influencing ocean circulation and climate. While some currents can be relatively slow, others, like the Gulf Stream, can achieve higher velocities and have significant impacts on weather and marine ecosystems.
