Mandiri Surf and Wind Quality by Season (Sumatra – Mainland, Indonesia)

The charts below show frequency of occurrence of a certain swell or wind in Mandiri, 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.
