Tourists were treated to the rare sight of whale sharks appearing simultaneously at two popular dive sites around Koh Tao in Surat Thani province on 5 July 2026. The whale sharks, each estimated to be 3-4 metres long, were seen swimming among schools of fish at Chumphon Pinnacle, northwest of the island, and Sail Rock, southeast of Koh Tao.

Divers were able to record photographs and video of the whale sharks as they moved calmly through the water, creating memorable encounters for both Thai and international visitors. The sightings occurred on opposite sides of the island, highlighting one of Koh Tao’s most celebrated marine attractions.
Ramluek Assawachin, president of the Koh Tao Tourism Business Association, said June to September is the period when whale sharks are most frequently seen around the island. During these months, sightings are regularly reported at several dive sites, including Chumphon Pinnacle, Sail Rock, Hin Khao, Kong Tung Ku, HTMS Pairin and other well-known underwater locations.
She said there are days when whale sharks are spotted at more than one dive site, with sightings at two locations almost simultaneously occurring on several occasions. According to Ramluek, this is the time of year that divers from Thailand and overseas eagerly anticipate because encounters with whale sharks can occur almost daily.
Ramluek said the continued presence of whale sharks is an important indicator of the health of Koh Tao’s marine ecosystem, reflecting abundant food sources and rich biodiversity. She added that the regular sightings also demonstrate the results of ongoing cooperation between government agencies, private organisations, dive operators and local communities to conserve and restore marine resources.

She said Koh Tao continues to be recognised as one of the world’s leading diving destinations. Regular whale shark sightings during the season not only provide memorable experiences for visitors but also reinforce the island’s reputation as a marine tourism destination that combines tourism with sustainable conservation.
Khaosod reported that local dive operators are continuing to encourage divers to follow responsible wildlife viewing practices. Visitors are being asked not to touch or chase whale sharks, not to feed them, and to maintain an appropriate distance to avoid disturbing their natural behaviour and to help preserve Koh Tao’s marine environment.
