A wave power converter employing independently staged surge energy capture for converting useful wave surge energy to electric power over a relatively broad range of surf conditions. The wave surge power converter includes an inclined ramp with several openings for receiving wave water into several independent chambers for capturing and retaining surge water in hydraulic isolation, a check valve in each chamber permitting water to flow into a conduit and a generator for producing electrical power from water flow in the conduit. The apparatus is suitable for low-cost manufacture, offers simple robust operation suitable for underdeveloped regions of the world, may be fabricated from commonly-available components, requires few moving parts and no valuable (lootable) components other than a generator, and is self-flushing for low maintenance operation.
