Following the heavy downpour last week, waves breaking on beaches in Chennai have turned black, which has evoked reactions that have ranged from panic to revulsion.
On Saturday, a number of visitors to the beaches, including Marina, Foreshore Estate, Eliotts and Thiruvanmiyur, reported that the sea had changed colour.
Visitors to these beaches on Saturday stayed away from the sea.
“This seems unusual. We have never observed the seawater taking on such a colour, at the Thiruvanmiyur beach,” said Pranav Vijay Sekar, an Anna University student who visited the beach on Saturday.
J. Savarinathan, a fisherman from Dommingkuppam, said such occurrences have happened during severe cyclones in the past.
“We do not venture into the sea for fishing during such periods. The smell is also bad,” he said.
