Monsoons ensure that one half of Sri Lanka’s coastal waters are always in season for all aquatic pursuits – the west coast from December to March and the north and east coasts from March to September, although July and October are best avoided. Visibility underwater in season is excellent and ranges from 50-100 feet. There are 138 species of brilliantly coloured coral recorded for Sri Lanka, harbouring stunning tropical fish and there is a wide coral shelf surrounding the island’s coast at intervals, from north to south, providing excellent diving opportunities.
