Jersey tide times & tide table

When is high tide in Jersey today?

Next high tide today is at 18:53 (9.6 m); next low at 13:07 (2.9 m). Times and heights are for St Helier harbour — other parts of Jersey's coast turn a few minutes earlier or later. Heights are in metres above Chart Datum, and the tide table above lists every high and low water for the day.

Can I cross to Elizabeth Castle, Corbière or St Aubin's Fort right now?

The crossings panel above shows the live open-or-closed status of each tidal crossing, straight from Ports of Jersey — the Elizabeth Castle and Corbière causeways, the St Aubin's Fort crossing, the Havre des Pas bathing pool and the marina gates. Causeways cover quickly on a rising tide — the sea can cut the route behind you well before high water — so check the next change time before you set out and allow plenty of time to get back.

Why are Jersey's tides so big?

Jersey sits in the Gulf of St Malo, where the English Channel narrows and funnels the Atlantic tide into a shallow corner of sea. The water has nowhere to go but up. That gives Jersey one of the largest tidal ranges in the world — around 12 m between low and high water on the biggest spring tides. At low water the island roughly doubles in size, uncovering miles of sand, rock and reef. Spring tides arrive with the full and new moon, when the sun and moon pull together; neap tides, about a week later, are far smaller. The cycle repeats roughly every two weeks.

Tide predictions and live crossing status are from Ports of Jersey, the island's harbour authority, refreshed every 10 minutes.
