Weather in the Channel is very unpredictable. Below are some of the weather and tide information websites that swimmers may find useful for organising training swims, as well as in the days leading up to the Channel Swim. Interpreting the information in conjunction with the changing tides is an art in itself - interesting and often frustrating when the conditions predicted are very different from those experienced. That is why the English Channel is so hard - and also so appealing to swimmers from all over the World.
