About This Spot
Shirasato is a beach break located on Japan's Pacific coast facing west toward the open ocean. The spot features a sandy beach with moderate wave exposure and consistent small wave conditions (1.17m average). The area is characterized by a combination of agricultural land and residential development immediately inland, with a defined beach strip separating the town from the water. Best conditions occur with northerly winds (0°) providing side-shore flow parallel to the coast. Wind reliability is low at 14.6%, suggesting inconsistent conditions throughout the year. Average water temperature of 16.8°C requires a wetsuit. The spot suits beginners due to manageable wave size and sandy bottom, though the low wind reliability means extended waiting periods between sessions. Kiters should be aware of coastal currents indicated by water color variations and potential shallow sandbars. The proximity to residential areas and infrastructure suggests moderate boat traffic and beach usage. Conditions are most stable during winter months when Pacific swells are more consistent.
