Balm, dry, and less humid period between May and October is considered to be the best time to visit Tahiti. Austral winter is known as a peak tourist season and lures travellers from all over the world to catch pearl harvest season, watch sharks, and do some diving and surfing. In July, you can also enjoy a few weeks of the Heiva celebrations full of traditional Polynesian singing and dancing. Even though long Tahitian summer from November to April brings in agonizing heat, unbearable humidity, and heavy downpours, there will be some sunny days to enjoy turquoise-water beaches, go see waterfalls and Tiare Tahiti flowers. Heavy rains during summertime are usually interspersed with periods of sunshine. That's why the rooms are still in high demand, and the rates remain high, even though resorts see fewer tourists.
