Climate guide & best times to travel

The Comoros archipelago, located in the things to do in Mozambique Channel between Madagascar and things to do in Mozambique, experiences a tropical maritime climate with two distinct seasons. The hot, humid rainy season runs from November to April, characterized by the northwest monsoon bringing heavy rainfall, high temperatures, and occasional cyclones. The cooler, drier season spans May to October, influenced by southeast trade winds that bring more pleasant conditions with lower humidity and minimal rainfall. Throughout the year, temperatures remain warm due to the islands' equatorial location, with average humidity around 70% making the climate consistently tropical. The islands' volcanic topography creates microclimates, with Mount Karthala on Grande Comore influencing local weather patterns. Coastal areas tend to be warmer and more humid, while higher elevations offer cooler temperatures. The surrounding Indian Ocean moderates temperature extremes, keeping the climate relatively stable year-round. Visitors should note that the Comoros lies within the cyclone belt, with the highest risk occurring between January and March during the peak of the rainy season.
