HIRLAM countries are -
Surface actual and forecast charts are available via KNMI site.
Unmodified HIRLAM Charts are available from the Italian MeteoMar site..
A note on these is on the Essential page. They are output direct from Numericl Weather Prediction models. They can be quite difficult to interpret and should be used with care. As is the case with GRIB forecasts, there has been no vetting or quality control.
UK Met Office
Charts from ECMWF for the next 10 days. There is the facility to look back and see what the model was producing on previous days and times.
To these can be added GRIB charts.
For notes se theEssential page.
Hawaii and the Central Pacific (latest)
For swell forecast charts for the Atlantic and UK, se the The National Centre for Ocean Forecasting (NCOF) site.
There are many other sites that give more links than appear above. The following will give many of these links but add others. There will be much duplication between sites. One that some may find useful is the MailASail service. This allows charts to be selected and requested by am automatically generated email. They are then received as an email attachment.
The weather.org.uk site has a comprehensive set of charts of all forms, including computer output.
Many others can be found at the Catalonian Infomet site and at Georg Mueller's Wetterzentrale site at Karlsruhe University. Charts include upper air and jet stream charts that are of little interest to the majority of sailors but are sought by a few cognoscenti. The Wetterzentrale site has archived charts as well as current ones. For the Archive charts, go to the Frame-Version. The Link for UK Met Office analyses is http://www.wetterzentrale.de/topkarten/tkfaxbraar.htm.
The Fleet Numerical Meteorology and Oceanography Center for numerous links to their charts worldwide.
The NOAA RadioFax site.
A comprehensive on-line NWS guide to marine products on the Internet.
Model output and other Prognoses a comprehensive links to computer forecasts, or products based on them, originating from major centres in Meteorology . The UK Weather Information Site Links to UK weather data, past, present and forecast.
Ogimet is a site with many types of data including many links to charts. Perhaps a good place to start.
