Aquatic life from coral reefs to fish in the Thailand’s eastern gulf coast is suffering as sea surface temperatures hit record highs this month amid a regional heatwave, worrying scientists and local communities.

The once vibrant and colourful corals, about five metres (16 feet) underwater, have turned white in a phenomenon known as coral bleaching, a sign that their health was deteriorating, due to higher water temperatures, scientists say.

Sea surface temperatures in the Eastern Gulf of Thailand reached 32.73°C (90.91°F) earlier this month while underwater readings are slightly warmer, with dive computers showing around 33°C, data shows.

If water temperatures do not cool, more coral will die, Lalita said.

“It’s global boiling, not just global warming,” she said.
