We also offer historical ocean and weather data for offshore projects.
Choosing Hindcast Points
The source of the data is the Global WaveWatch III model which is on a fixed grid where latitudes are spaced at 1.0 degrees and longitudes at 1.25 degrees. The Virtual Buoy point you choose below must be a valid grid point. With our regional models and the latest global model being .5 degree, the historical point may not match up exactly with the Virtual Buoys. We have a map tool to help you find the nearest hindcast point. The latitude needs to be rounded to the full degree. Longitudes are on the 1.25 interval starting at 0 so the point must be evenly divisible by 1.25 to be on the grid. It is important to understand model data when choosing and analyzing points. Here are some key items to consider:- Inland seas are not covered by the historical data on the website. Examples: Mediterranean, Red Sea, Caspian etc. However, inland seas are covered by our bulk historical data, described here.
- Points must be on the model grid and over water. Points on or too close to land will not have wave data.
- The model provided here is most valid for deep water, offshore points. Shallow water, local points, small islands, or any topography altering winds/waves may not be fully resolved by the data provided here. This model provides outlying conditions only.
- Tropical Cyclones may not be fully resolved depending on the event, so the full effects of tropical storms, hurricanes, and typhoons may not be apparent. Global scale models often lack the resolution to fully estimate winds around tropical systems.
