As beautiful as Sri Lanka is on land, it is equally matched with its spectacular underwater scenery. Beneath the waters of the Indian Ocean lies a separate world of tropical fish, coloured coral and mysterious shipwrecks. Located 5 to 9 degrees north of the equator means that the Sri Lanka seas are perennially warm and when in season they remain at an inviting temperature of around 27C. Sea conditions are governed by the two monsoons – the northeast and southwest- permitting calm seas and clear waters along the south and western coastline from November to April and from April to October along the eastern coast of the island. Diving and snorkeling in Sri Lanka is all the more interesting because of the different types of reef that is found in the seas around the island. There are sandstone platforms, coral banks, boulders and rock cliffs that are found both close as well as far away from the shore. Most of the reefs found on the western coast are sandstone platforms. In the Southwest and southern coast rock boulder reefs are more common as are small fringing coral reefs.
Hikkaduwa – With its impressive coral reefs and abundance of tropical fish, Hikkaduwa is recognized as one of the best places for Snorkeling and diving on the Southwest coast (in the southwest season of November to April). With a reputed and long-running diving school located in the town itself, PADI diving instructors are available throughout the season for training and certification as well as leading more experienced divers in some of the country’s best ship wreck and reef dives.
