Norfolk Tides is an online tide-information resource for people planning activities along the Norfolk coast and waterways. Its website presents tide times and heights for a wide range of locations, from Blakeney Bar, Cromer and Wells to Great Yarmouth, Hunstanton and inland river sites. Visitors can select a destination to view local tide tables, including upcoming high and low tides, and find related details such as sunrise and sunset times.

The information is designed to be easy to read and useful for sailing, surfing, kayaking, paddle boarding, windsurfing and beach visits. Norfolk Tides also explains how its figures are calculated, including adjustments made using data from Immingham, and provides frequently asked questions for further guidance. Users can create custom tide calendars and add them to a phone, tablet or computer; the site also promotes calendar, widget and poster options. Tide data is adjusted for daylight saving where appropriate, and the website clearly cautions that its tables are not intended for navigation.
