Tidal streams around Jersey, the Channel Islands, France and South coast of England

tide stream directions in the Channel islands

Tide streams in the Channel islands

I’ve discovered this excellent Online tide stream and swell data resource produced by Ifremer/Marc in France.

This French and English site has tide streams for Jersey, Guernsey and the English Channel.

It is possible to see hour by hour tidal stream data around the coast in more detail than the Admiralty tidal stream atlas.

What I find impressive is the level of detail and accuracy of the tide stream atlas on Marc.

The data is presented in metres per second so you need to convert into knots via a converter site such as Onlineconversion.com A metre per second is roughly 1.95 Knots.

Marc has been created in partnership with the French Naval Hydrographic and Oceanographic Service, Meteo France, Ifremer and other French marine research organisations.

Wave height data, wave-buoys, tidal streams, tidal surges, sea temperature, salinity Phytoplankton production and other data can be accessed via Marc.

Plenty to keep you busy following the changes in the ocean and planning trips.

My thanks to Colin at Sea kayaking Brittany for alerting me to this site.
