  1. National Ocean Service parties have reported that off East Point tidal currents of about 1 knot set NW and SE in calm weather. Close to East Point strong currents set N and S. Trade winds increase the NW flow and decrease the SE flow. A very strong W current setting around East Point and thr ough Buck Island Channel was noted when the trade ...

  2. Tides are really big waves that move through the ocean in response to the forces exerted by the Moon and the Sun. Tides involve water moving up and down. Currents involve the movement of water back and forth , driven by factors such as tides, wind, the shape of the land, and even water temperature.

  3. Currents. Currents put motion in the ocean! Tides involve water moving up and down; currents involve the movement of water back and forth. Currents are driven by several factors. Tides are one of these. Wind, the shape of the land, and even water temperature are other facts that drive currents. Related links.
