High waves hit the southern coast of Gunungkidul Regency, Yogyakarta, on Tuesday morning, August 11, 2026, causing damage to boats and coastal buildings. The Meteorology, Climatology, and Geophysical Agency (BMKG) reported that the phenomenon is expected to continue for the next few days.
According to local authorities, the waves reached heights of up to 4 meters, damaging at least five fishing boats and several beachfront stalls. No casualties have been reported, but officials have urged residents and tourists to stay away from the shoreline.
BMKG's early warning system indicated that the high waves are driven by strong wind patterns in the Indian Ocean. The agency has issued a warning for coastal areas in Yogyakarta and neighboring regions, advising fishermen to postpone activities at sea.
Local disaster management agencies are monitoring the situation and have set up temporary barriers to protect vulnerable areas. They are also coordinating with village officials to ensure the safety of residents living near the coast.
Residents are advised to remain vigilant and follow updates from official sources. The high wave warning is expected to remain in effect until at least August 14, 2026.
