Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 4 years of historical weather data.
Partially sheltered coastline with moderate, varied conditions
St Mawes is located on the Roseland Peninsula in Cornwall, UK, positioned at the entrance to the Carrick Roads estuary where it meets the English Channel. The spot features a south-easterly facing coastline with shallow bay waters protected by rocky headlands. The bay provides moderate fetch from the south and southwest, with the water type characterized as rough-chop typical of Atlantic-influenced UK coastal areas. The spot suits intermediate kiters comfortable with rocky terrain and variable conditions. Best winds approach from the southwest to west (around 45°), providing reliable side-shore conditions. Wind reliability is relatively low at 36.9%, typical for southern UK locations. Average wave height of 1.11m indicates small swell conditions; larger swells require winter storm systems. Key considerations include navigating shallow areas and rocky outcrops visible along the shoreline, respecting boat traffic in the estuary entrance, and understanding tidal flows which can be significant given the location at a major tidal channel. The proximity to residential areas requires responsible launch and landing procedures. Water temperature averages 12.3°C, necessitating appropriate thermal protection.
