The islands have a tropical climate. The South-west Monsoon sets in Andaman Nicobar islands towards the end of May and the North-east Monsoon in November. There is no fury of hot summer, no chilling winter, no water clogging or traffic jams. For those who want to enjoy boating, swimming, snorkeling, sightseeing all 12 months is season. North Indians find relief from burning heat and chilling winter if they visit the island from May/June/July and in December/January. Season for nature lovers is May to December when forest is lush green and waterfalls are at their prime. Divers can enjoy the best during December to April and bird watchers during winter times.
