Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 4 years of historical weather data.
Waves breaking on sandy bottom, varied conditions
Porthleven is a working fishing harbor located on the south coast of Cornwall, facing south toward the English Channel. The spot comprises a sandy beach with an enclosed harbor to the north, bounded by prominent rocky headlands. The beach faces directly south, making easterly (90°) or westerly (270°) winds optimal for side-shore conditions. Given the 11.4 knot average wind with modest reliability (39.2%), conditions are variable. The 1.72m average wave height suggests this is better suited for intermediate kiters who can handle moderate sea states and navigate around harbor infrastructure. Low wind reliability indicates sessions may be inconsistent. Key considerations include respecting the active harbor traffic, understanding tidal movements through the harbor entrance, and being aware of rocky hazards along the northern section. The spot's exposed southern aspect provides reasonable fetch for local wind generation. Water temperature averaging 12.1°C requires appropriate thermal protection.
