High frequency radar can measure the speed and direction of ocean surface currents in near real time. These radars can measure currents over a large region of the coastal ocean, from a few kilometers offshore up to 200 km and can operate under any weather conditions. They are located near the shoreline, and need not be situated atop a high point of land.
