The Palk Strait (Tamil: பாக்கு நீரிணை Pākku Nīriṇai, Sinhala: පෝක් සමුද්ර සන්ධිය Pok Samudra Sandhiya) is a strait between the Tamil Nadu state of India and the Jaffna District of the Northern Province of the island nation of Sri Lanka. It connects the Bay of Bengal in the northeast with Palk Bay in the southwest. It is 40 to 85 miles (64 to 137 km) wide and 85 miles long.[1] Several rivers flow into it, including the Vaigai River of Tamil Nadu. The strait is named after Robert Palk, who was a governor of Madras (1755–1763) during the Company Raj period.
The unique feature around Palk Strait is that the waves around it, to its north and south are of high contrast. To the north, the waves of Bay of Bengal are mostly swells waves[2] while that on the south, in Palk Bay, are mostly sea waves.[further explanation needed] Despite being a sea dominated area, the significant wave heights in Palk Bay regions are relatively low. The average significant wave height in Palk Bay close to Ram Setu is around 0.5 m.[3]
