A dynamic graph of significant wave heights averaged and updated each day. This product is generated using data from CDIP buoy (located 22 NM west of Pt. Reyes, CA), measuring the 1/3 highest waves every 30 minutes. Plots of daily wave heights for each year since 1997 are represented on the graph, with the current year data highlighted. A long-term mean line, created by averaging wave heights from all previous years (updated every year), is also included on the graph for comparing with the current year wave heights. The maximum daily averaged wave height measured since 1997 is also displayed (23.2 ft on Jan 19th 2010).
