Cornwall Tides is an online tide-information service designed to help people plan visits and activities along the Cornish coast. Its easy-to-read tide tables cover towns and beaches across Cornwall, including Boscastle, Bude, Falmouth, Newquay, Padstow and St Ives. Visitors can look up daily high and low tide times and heights, along with sunrise and sunset information for selected locations.

The site presents tide data in monthly calendars and explains how local times and heights are adjusted from reference locations. It also provides frequently asked questions about its calculations and clearly states that its tide information is not intended for navigation. The service is aimed at people sailing, surfing, kayaking, paddle boarding, windsurfing or enjoying a day at the beach.

Alongside tide forecasts, Cornwall Tides offers a custom tide-calendar service that users can add to a phone, tablet or computer. The website also features a calendar widget and poster, plus location menus and information pages to help visitors find relevant coastal forecasts and understand the service.
