Shell sea conditions & tide times

Shell is a coastal location in Herm, one of 9 Herm spots covered by NippyIndex.

The shore faces broadly east, so it is most open to wind and swell arriving from the east.

As a tidal location, its tide predictions are referenced to the nearest UKHO tidal station.

NippyIndex draws on published marine and weather data (sea state, wave information and water temperature) and UKHO tidal predictions.
