Tahiti, French Polynesia

Located in French Polynesia, Tahiti boasts an Af Köppen climate classification, an indicator of a tropical rainforest climate. Devoid of a discernable winter season, the island experiences warm temperatures and a significant amount of rain throughout the year.

A conspicuous trait of this climate type is temperature consistency, a phenomenon evident in Tahiti. Sea temperatures remain warm throughout the year, fluctuating between a minimum of 26.4°C (79.5°F) and peaking at 28.9°C (84°F).
