Mayotte is an archipelago consisting of two main islands, Grande-Terre (or Maore) and Petite-Terre (or Pamanzi), plus some smaller islets. The archipelago is an overseas department of France and is located in the Indian Ocean, at a latitude of nearly 13 degrees south.
The capital is Mamoudzou and is located on the east coast of the main island.
The average daily
temperature ranges between 28 °C (82 °F) in the warmest period (January-April) to 25/26 °C (77/79 °F) in the coolest period (June-September). From June to September, the temperature never exceeds 32 °C (90 °F), while from November to March, it can sometimes reach 34/35 °C (93/95 °F), morevoer, high humidity in this period makes the heat uncomfortable.
