Bang Saen Beach Waters Turn Dark and Murky
Tourists are avoiding the water at Bang Saen Beach in Chonburi after the sea turned a dark, mud-like color, prompting concerns over water quality.
On September 3, 2026, reports emerged from Bang Saen Beach in Saen Suk, Chonburi, describing the seawater as dark and murky, resembling mud. According to Khaosod Online Thailand, the unusual discoloration has led many visitors to refrain from swimming due to concerns regarding potential skin irritation or health impacts.
Local tourism has reportedly slowed as a result, with the beach area appearing quieter than usual. One visitor, who traveled from Udon Thani, expressed disappointment after finding the water conditions significantly different from a previous visit four years ago, ultimately deciding to keep her children out of the sea. A local vendor noted that the region is currently experiencing monsoon conditions and heavy rainfall, which may be contributing to the environmental change.
For travelers and residents, this situation highlights a temporary decline in water quality that may affect recreational plans. While the discoloration is visually concerning, it remains to be confirmed by local authorities whether the water poses any specific health risks or if the phenomenon is strictly a result of seasonal runoff and sediment displacement caused by the ongoing monsoon. Visitors are advised to monitor local updates before planning water-based activities in the area.
