As it is surrounded by the Indian Ocean, Sri Lanka has some of the best diving spots in the world. Seawater temperatures remain around 27 degrees Celsius and underwater visibility during the high season, which is from November through April on the southern and western coasts, is between 15m to 40m. Some of the best diving spots are found from Beruwela to the beach resort of Unawatuna on the south coast. There are many coral reefs, submerged shipwrecks and exotic fish that the ocean offers all divers.
