Formed during the last ice age, Chichester Harbour is a classic ria, or drowned river valley, created when rising sea levels flooded the original river valleys. The harbour features extensive mudflats, salt marshes, and sand dunes, underlain by London Clay and Reading Beds. This unique geological formation creates the distinctive fingers of water and peninsulas that characterize the harbour's appearance.
This natural harbour has been a center of maritime activity for over 2,000 years, from Roman settlements to medieval trading ports. The harbour played a crucial role in shipbuilding during the 18th and 19th centuries and served as a strategic location during World War II. Today's landscape reflects this rich heritage through historic villages, ancient churches, and traditional fishing communities that dot the shoreline.
The harbour encompasses 3,733 hectares of protected landscape, featuring distinctive landmarks such as Itchenor's historic waterfront, Dell Quay's ancient port, and the picturesque Bosham Channel. The area includes 27 miles of public footpaths, including the popular Harbour Way trail. Multiple sailing clubs, marinas, and the Chichester Harbour Conservancy's education center make this AONB a hub for maritime recreation and environmental education.
Chichester Harbour enjoys a mild maritime climate typical of southern England, with average summer temperatures around 20°C (68°F) and winter temperatures rarely falling below 5°C (41°F).
