The hurricane prevention system and method for use in ocean water is provided including a buoyant platform on which is disposed a wind-driven power source, a water-moving system, and a water-dispersing system. The wind-driven power source is configured to use wind energy to power the water-moving system, which is configured to transport water from somewhat deeper ocean water levels to, or near, the level of the ocean. The water-dispersing system is preferably configured to disperse the water from the water-moving system to an area at or near the sea surface. The buoyant platform preferably is anchored by a mooring system. The hurricane prevention system and method is designed to bring cooler water from deeper in the ocean to or near the ocean surface and to disperse that cooler water in that area to reduce the sea surface temperature, thereby preventing or inhibiting the formation of hurricanes.
