The sun on the Comoros is dominant throughout the year. The sun shines for many hours a day during the monsoon months, but the sunniest time is during the trade winds from May to November, when clouds can form near the mountains. The sea temperature is ideal for swimming all year round: Temperatures range from 25 degrees in August to 29 degrees in the period from February to April.The climate in the Comoros, the archipelago of the Indian Ocean south of the equator, is tropical, with a warm and rainy season from December to February, when the northwestern monsoon predominates, and a relatively cool and dry season from Dezember to Februar, when the southeastern trade winds predominate. The average daily temperature of the capital Moroni on Grande Comore ranges from 27 degrees in the hottest period (January to April) to 23 degrees in the coolest months (July, August and September). Among the three main islands of the archipelago, the two smaller ones, Moheli and Anjouan, are covered with hills in the central part, while on the largest island, Grande Comore or Ngazidja, there is a real mountain, the Karthala volcano, which is 2,360 metres high. The reliefs form cloud formations that can cause showers and thunderstorms, especially on the main island, which is actually the most rainy. On Karthala it rains 5,000 millimetres per year, while Moroni is on the windward side during the rainy season (i.e. exposed to the northern monsoon at 2700 mm per year).When is the best time to travel to the Comoros?
The best time to visit the Comoros and enjoy their not yet crowded beaches is from June to October. It is the driest and sunniest time of the year, although there may still be some showers on the main island.What kind of clothes should you take with you?
