Île du Lys (also: Ile du Lise , Le Lys dt .: Island of the Lily ) is a small island of the Îles Glorieuses , north of Madagascar at the northern end of the Mozambique Strait . Politically, they belong to the Îles Éparses , a district of the French overseas territory Terres australes et antarctiques françaises .

geography

The Îles Glorieuses are located in the western Indian Ocean, around 210 km northeast of Cap d'Ambre, the northern tip of Madagascar, and around 250 km northeast of Dzaoudzi on Mayotte . The islands, surrounded by an extensive coral reef, are flat, parts of the lagoon fall dry at low tide. The Île du Lys has far less vegetation than Grande Glorieuse and consists mainly of limestone rocks. A larger sand hill and a salt water lagoon define the landscape. The island is elongated, about 600 m long and surrounded by large sandbanks that are dry at low tide.

climate

The climate is tropical and shows only slight temperature fluctuations over the course of the year. From May to November the archipelago is subject to the influence of the southeast trade winds ; During this time the average temperatures are between 24.8 and 27.7 ° C, the relative humidity is 75–81%. During the dry season from September to November there is little rainfall. The northwest monsoon dominates from December to April ; With high humidity (81–84%) and average temperatures of around 28 ° C, there is considerable rainfall of around 100 to over 200 mm per month. During the warm season, the islands are occasionally hit by tropical cyclones.

natural reserve

The island has been designated an Important Bird Area (IBA) by BirdLife International due to a very large colony of around 100,000 pairs of Black Terns (Onychoprion fuscatus) and 100 pairs of Noddis (Anous stolidus).
