FAQ
Why are the tides so big at Jersey?
The shape of the Gulf of St-Malo amplifies the tidal wave: at Jersey the range reaches 11–12 m at springs, among the highest on Earth. Beware very strong currents and a fast-returning tide on the flats.
Do these times apply to the British isles?
Yes : times are computed in Paris time (like the whole site). As the islands use UK time (GMT/BST), subtract one hour locally. As always, these are indicative predictions.
