Japan Surf Map – Wind and Wave forecasts

Japan wave (swell) map for surfers, windsurfers and sailors showing open ocean wave size, wave period and wave energy. You can customize the wave and wind maps with overlays for wind arrows, pressure and general weather for surfing. There are also options to display live wind observations from ships, wave buoys and weather stations on the wave maps in the Japan region.
