Cornwall Tide Safety and Cut-Off Risks

Tide planning is not just about the time of low water. The return journey, weather and local geography matter too.

Why people get cut off

Many Cornish beaches and coves have headlands, gullies, causeways or narrow access paths that disappear before high water. A route that looks open at low water can close quickly when the flood tide starts to run.

Plan the whole window

Check the next low water and the following high water. Leave time to walk back, and add a margin for slower walking, children, dogs, slippery rocks and changing weather.

Weather can raise the sea

Low pressure and onshore wind can push the real water level above the astronomical prediction. Tide Checking shows the live gauge difference where available, but that is still a gauge reading, not a guarantee at every cove.

Use official warnings

For dangerous conditions, storms, navigation or rescue decisions, use official sources and local signs. Tide Checking is a planning aid, not an official safety service.
