Check the latest South Carolina wave height charts showing wave height and direction as it changes over time. The longer the period, the more wave energy is contained within the swell and the faster and deeper beneath the sea surface it travels. The surf report and wave height forecast for your region. 7 kts. Wind, waves & weather forecast Surfside Beach/Freeport. Dominant wave period 6 seconds. Significant wave height, WVHT, is approximately equal to the average of the highest one-third of the waves, as measured from the trough to the crest of the waves. Slight chance of showers in the morning, then chance of showers in the afternoon. The arrows show the wave propagation direction. It is believed that the statistical distribution of the wave height is well approximated by the Rayleigh distribution, so if we estimate 10 meter height, it can be expected that one of the 10 waves is greater than 10.7 meters, one of 100 waves is greater than 15.1 meters, one of 1000 waves is more than meters 18.6. Significant wave height is the statistical basis for all wave heights presented in text forecasts and map displays. Wave height, wave direction, and wave period are recorded in 30 min intervals. The statistical definition is calculated as the average height of the highest one-third of the waves experienced over time. The significant wave height: observations (blue), wave model forecast (red). Wave heights are variable over time. Dominant wave period 5 seconds. Waves. Tide height (m) Sunday, Dec 06 Wind. When the buoy is not in the sea or observational data are not available for technical reasons, the results calculated by the wave model are shown in both the graph and the table (with magenta in the graph). Get the latest wave observations for Waimea Bay, Oʻahu, Hawaiʻi! Slight chance of showers. SATURDAY South winds 13 to 18 knots. are usually described by their height, H, wavelength, L, and wave period, T. Wave height is the distance between the trough and crest of the wave. Seas 2 to 4 feet. The wave period is the time for two consecutive crests to pass a fixed point. Wave height (m) Wave period (s) Tide type. Tides.
