Indonesia Sumatra Mainland Surf Forecast map for predicting the best wave and wind conditions across the region. For surfers, the map shows the most powerful swell tracking across near-shore open water and not the peak waves experienced by boats out at sea. Move your mouse over the ocean swell symbols or the surf breaks on the coastline to see a more detailed surf forecast including wave period and wind conditions. The forecast updates every 6 hours and most live weather reports update every hour. You can animate the Indonesia Sumatra Mainland Surf map or show live wind and wave conditions as reported from wavebuoys and local weather stations. Surf breaks shown along the Indonesia Sumatra Mainland coastline are also listed below.
