Map - Mayotte

The island of Mayotte, overseas department of France, is located on the Indian Ocean, at a latitude of nearly 13 degrees south. Its climate is tropical, with a warm, wet and rainy season from December to April, when the north-west monsoon prevails, and a cool, dry and sunny season from June to October, when the south-east trade winds prevail, while May and November can be considered as transitional months.
The average daily temperature ranges between 27 °C in the warmer period (January-April), to 23/24 °C in the least warm period (June-September). From June to September, the temperature never exceeds 32 °C, while from November to March, it can sometimes reach 34/35 °C, but in this period it's the humidity which makes the air uncomfortable in this period.
Here are the average temperatures.

The total annual rainfall is not very high, and amounts to 1,200 millimetres in the small island of Pamanzi, and 1,400 mm in the main island, most of which occur from October to May; the rainiest month is January, when the rains are heavy.

During the rainy period, however, the amount of sunshine is acceptable, because the tropical rains occur mainly in the form of downpour or thunderstorm, intense but not long lasting. Anyway, this period, in addition to being sultry, also presents the risk of tropical storms or cyclones, which are more likely from late December to mid-April.
During the dry period, some brief thunderstorms are still possible, but in the island of Mayotte they are very rare in the period of the trade winds, because it is flat (therefore there are no mountain ranges which could be able to foster cloud formation), and also because it is protected by Madagascar, which is located just 300 kilometres to the south-east.


The sea temperature is always warm enough for swimming, in fact it fluctuates from 26 °C from July to September, to 29 °C in the February-April period.

When to go

The best time to visit Mayotte for a beach holiday goes from June to October: the temperature is pleasantly warm, the sunshine amount is good and the rains are rare.

What to pack

In winter (June to August): light clothes, a sweatshirt for the evening, a scarf for the breeze. For the reef, equipment for snorkeling, water shoes or rubber soled shoes.
In summer (December to February): tropics-friendly, loose fitting clothing, light shirts and pants of natural fibres (cotton, linen), light sweatshirt for the evening, light raincoat or umbrella for the rain showers.
