Box jellyfish are fairly common on some Thai beaches. Stings by these venomous sea creatures can be debilitating, causing so much pain – and shock – that the injured victim cannot even swim back into shore after contacting a box jellyfish in the ocean. Luckily for us, we can predict when these pests are most likely to be active and plentiful in waters around Thailand.
Several species of jellyfish, mostly harmless, can be found seasonally in Thailand. However, Box Jellyfish are initially found off the beaches of Ko Lanta and Hat Nopparatthara Beach next to Ao Nang Beach – Mu Ko Phi Phi National Marine Park off Krabi province, Nam Bo Bay in Phuket province and often off Hua Hin and Cha-am Beaches in Phetchaburi province, as well as Ko Tao in Chumphon province, Ko Samui, and Ko Pha Ngan in Surat Thani province.
