Sailing to the British Virgin Islands in the Caribbean 1500
Sea State Analysis Charts
|This is an example of a sea state analysis chart, reduced in size to fit on this page (click the chart to see it actual size, use your browser's "back" command to return here). This chart is for 1200 UTC November 1, 2007 and shows Hurricane Noel heading up the coast.
These charts show the significant wave height (in meters) and the dominant wave direction for the North Atlantic, the extreme northern Caribbean, and the Gulf of Mexico. All the charts are courtesy of the National Climatic Data Center (internet link below).
I have a set of charts covering 1200 UTC November 1, 2007 to 1200 UTC November 20, 2007 (November 18th is missing) with one chart per day.
