Significant wave height of a swell

WebA good general guide is to multiple the height by 1.5x to find the largest waves and hence the range of likely surfable waves: 2ft = 2-3ft range. 4ft = 4-6ft. 6ft = 6-9ft. 12ft = 12-18ft. … WebMarine Weather. 24-hr Forecast. 48-hr Forecast. 72-hr Forecast. Updated at 5:01 pm Wed 12 Apr. Swell waves are wind-generated waves that have moved away from their area of formation. As the swell travels far away from their source area, its height decreases and wavelength increases.
