Portland Harbour

Portland Harbour is a semi-enclosed bay on the Dorset coast facing northwest, providing natural protection from extreme ocean swells. The spot features shallow water areas with mudflats and sand, typical of a tidal estuary environment. A green breakwater structure visible in satellite imagery provides some wind protection but creates confined water conditions. The harbor setting means limited fetch, resulting in the documented 1.16m average wave height. Wind reliability at 46.8% reflects the sheltered nature and local wind shadow effects from surrounding geography. Best conditions occur with northeasterly winds, which approach the bay as side-shore parallel to the coastline. This spot suits intermediate kiters comfortable with variable conditions, shallow water transitions, and proximity to fixed infrastructure. The tidal nature means water depth fluctuates significantly; local knowledge of tidal windows is essential. Low wind days are common, requiring patience or alternative spot selection. The relatively mild average temperature and moderate wind speeds make this accessible for year-round progression work rather than thrill-seeking conditions.
