An underwater wave energy converter (WEC) (10) has a piston (32) that reciprocates up and down as recurring waves (22) pass over. Downward motion of the piston (32) drives the rods or plungers (50b) of a multiplicity of hydraulic jacks (50) to pressurize hydraulic fluid in an energy conversion system. Ultimately, the energy conversion system powers one or more hydraulic motors (511, 512) that drive an electric generator (510) or multiple generators. A sensor system (25) detects characteristics of in-coming waves such as by detecting changes in pressure as in-coming waves (22) pass over the sensor system (25). The sensors can be mounted on the ocean floor seaward from the WECs (10), and a control computer system (231) calculates characteristics of the in-coming waves such as wave height and speed data, and uses the data to control aspects of the WECs (10) and other components of the energy conversion system.
