Buma Surf and Wind Quality (Japan – Okinawa, Japan)
The charts below show frequency of occurrence of a certain swell or wind in Buma, broken down by both direction and strength (wave height).
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
