We've changed the buoy information that is featured on the front page graph. It used to show the NOAA Station 46026 located 18 miles west of San Francisco. It now shows data from the CDIP 142 buoy, located approximately 4 miles southwest of the Pt. Bonita lighthouse.
The data should be better. Let us know what you think. We've also cleaned up the swell prediction algorithms that show the two day prediction on the graph. It should be much more accurate now.
