About Assumption Island
Assumption Island is a remote raised coral island in the Aldabra group of the Seychelles Outer Islands, about 1,140 km southwest of the main granite islands and about 30 km southeast of Aldabra Atoll. Covering about 1,171 hectares, it is the largest outer island after Aldabra.
Most of it is flat limestone only a few metres high, but dunes in the southeast reach about 30 m, the largest dune system in Seychelles, and a 5.5 km white-sand beach runs from the old jetty by the small village.
Guano mining for much of the 20th century stripped most of the vegetation and wiped out many native birds, and recovery is slow. Sea turtles still nest on the beaches, a few giant tortoises live here, and the coral reefs are rich; parts of Jacques Cousteau's film The Silent World were shot here.
- Climate
- Hot and tropical all year, with a rainy season from about December to March and a long dry season from about May to November. Daytime highs are about 29 to 32 C, warmest from October to January, and nights are about 20 to 23 C, coolest from June to September. January and February are the wettest months, with about 240 mm of rain a month on about 15 days; March and December bring about 130 to 160 mm. From May to November rain is light, often only about 10 to 30 mm a month on 2 to 4 days, and April is a short change-over month. Rainfall is about 950 mm a year. These are approximate averages from the nearest official station with full monthly normals, at Antsiranana in northern Madagascar, about 420 km away, so conditions on the island may differ.
