Welcome to a comprehensive page of top weather forecast sites for the Channel Island and neighbouring Brittany and Normandy coasts. So if you live in Guernsey or Jersey, this is the site for you!

My favourite weather forecast sites

Windguru – www.windguru.cz/ – tried and tested and works well. The GFS27km will give a 10 day forecast and the 9km will provide a more detailed forecast for the new 3 days. It is available free or for an annual subscription which provides more up to date and better (in theory) data. Not expensive so a worthwhile investment for a serious boater.

Windfinder – recently much improved and provides everything you could need. https://www.windfinder.com/forecast/guernsey
It provides impressive information including wave heights and is free of charge.

I have often wondered what Force 5 in the “North” means. Sounds like F5 in the Vale parish, but could be Alderney. A recent response to Martin Nickolls’ letter included the following information:
“The CI Shipping forecast area extends about 100 miles from latitude 50 degrees north to the Brittany coast. Often the wind speed in mid Channel (the north of the area) and near the Brittany coast (the south of the area) differ by two Beaufort forces, the difference between a safe passage or danger for a smaller boat.”
