Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 6 years of historical weather data.
Waves breaking on sandy bottom, varied conditions
Shirahama is a developed coastal beach break on Japan's Izu Peninsula, facing west toward Suruga Bay. The spot features a sandy beach backed by dense forest and residential areas, with visible rocky formations and reef structures particularly at the southern end. The beach is relatively narrow with steep elevation changes from forest to sand. Wind reliability is moderate at 33.5%, with average winds around 10.6 knots, suggesting this spot works best during seasonal wind patterns. Wave heights average 1.5m, indicating this is a smaller wave spot suitable for progression rather than power. South winds (180°) would provide side-shore conditions parallel to the beach. The presence of shallow reef areas, submerged rocks, and limited exit corridors makes this an intermediate-level spot requiring good local knowledge. Best suited for intermediate kiters during consistent wind windows. Access is feasible through the developed areas, though crowding potential exists given residential proximity.
