Vast quantities of seaweed have accumulated along the Thoothukudi coastline. Local fishermen have clarified that this is a common and natural seasonal occurrence driven by strong winds and waves, assuring the public there is no cause for concern.
Large quantities of seaweed have washed ashore along the eastern coastal areas of Thoothukudi district. The seaweed, which is commonly found in the sea, has drawn the attention of the public after accumulating along the shoreline.
Speaking about the phenomenon, local fishermen said that it is a common natural occurrence for seaweed to be washed ashore by waves during periods of strong winds. They added that there is no cause for concern, as this is a regular seasonal event.

According to marine enthusiasts, the seaweed, which naturally grows in the Gulf of Mannar marine ecosystem, was believed to have been carried to the shore due to changing ocean currents and seasonal wind patterns.
