Bora Bora is located in the
Society Islands, which are part of
French Polynesia, and is located northwest of Tahiti, about northwest of Papeete, Tahiti. It also has around it several motus ( is a Tahitian word meaning "small island"), which are small elongated islets that usually have some width and vegetation. One of the most beautiful and photographed motus in Polynesia is
Motu Tapu, to the west of the main island, especially before a hurricane carried away part of the tongues of sand at its ends. , Bora Bora
Dimensions Bora Bora is among the smaller of the islands of the Society archipelago: the main island measures only from north to south and east to west; the total area of Bora Bora, including islets, is less than . Bora Bora is an area of mountainous central island, which is an extinct volcano, itself surrounded by a lagoon separated from the sea by a reef. The highest point is
Mount Otemanu, at .
Description Bora Bora is formed by an extinct volcano, surrounded by a lagoon and a fringing reef. Its summit is Mount Otemanu, located in the center of the atoll; another summit,
Mount Pahia, on the main island is high. The main island has four open bays overlooking the lagoon: Faanui
Bay, Tuuraapuo Bay and Povai Bay to the west, and Hitiaa Bay to the northwest. Tuuraapuo Bay separates the main island from two islets of
volcanic nature: Toopua and Toopua-iti. Necklace-shaped coral reefs surround the central island and protect it from the open sea as if it were a dike. It is a
barrier reef with only one opening to the ocean: the Teavanui Passage, located west of the main island, which allows most large cargo ships and cruise ships to enter the lagoon. They must, however, stay in the channel, as much of the lagoon water is shallow outside the Teavanui Passage. The barrier reef is very wide in some sections, where it exceeds two kilometers in width to the southwest of the island. To the east and north of the island, the reef supports a series of islets made up of coral ruins and sand (the motu). One such motu in the north, the Motu Mute, is where the
U.S. Army built an
air base during the Second World War, which has now become the airport of Bora Bora. The lagoon, abundant in fish, is remarkable for its breadth and beauty. Its color varies with depth: dark indigo when it is deep (Teavanui Passage, Poofai and Faanui bays) and pastel shades of blue and green elsewhere.
Corals, when they are very close to the surface, along with the fauna that colonizes them, come to wear a wide variety of colors: egg yolk, red, blue or purple.
Geology Bora Bora is part of a group of
volcanic islands linked to the activity of a hazardous area. It is an extinct volcano which was active in the Upper Pliocene (between 3.45 and 3.10 million years ago), and then underwent at least partial depression and strong erosion under a hot and humid tropical climate. The bay of Tuuraapuo was the main
crater of the volcano, whose collapsed southwestern edge only subsists still in the islets Toopua and Toopua-iti, which culminate respectively at and , altitude. The volcanic rocks are of basaltic type, consisting mostly of alkaline basalts, some hawaiites, and some gabbro intrusions, especially on the islet Toopua. They come mostly from voids, with explosive episodes being rare.
Climate Bora Bora has a
tropical monsoon climate. Temperatures are relatively consistent throughout the year, with hot days and warm nights. The dry season lasts from June to October, but there is some precipitation even during those months. The rainy season is between November and April, with a heavy atmosphere and sometimes violent
storms resulting in heavy rains. These rains can last several days, but this does not preclude many sunny days during the wet season. The humidity level usually ranges from 75% to 90%, sometimes reaching 100%. The dry season is between April and October, with warm and fairly dry weather, but the trade winds sometimes blow strongly. The days are still sunny, but although the dry season is present, this does not prevent the occurrence of some showers or even thunderstorms in the
afternoon. During the dry season, the average humidity level remains between 45 and 60%; sometimes, this level rises spontaneously to 80%, especially at
night when the ground heat remains high and exceeds a certain threshold. These "dry season" storms will occur in the afternoon. ==Tourism==
