Country Summary

This page presents high-level information for Comoros's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Comoros's country context and climate is provided following the visualizations.

The Union of Comoros is a small archipelago in the southwestern Indian Ocean nestled between the coast of East Africa and Madagascar in the Mozambique Channel. Comoros is composed of three islands: Grande Comore, Mohéli, and Anjouan, and is made up of diverse coastal and marine environments from low coasts to cliffs, mountains, and an active volcano. The economy is dominated by the primary sector, which employs 70-80% of the active population, and contributes to 51% of gross domestic product. The agricultural sector is primarily focused on the production of Comoros’ three primary export crops (vanilla, cloves, and ylang-ylang). Poverty is widespread throughout the Comoros, with 45% of the population living below the poverty line. Lack of employment opportunities is a large contributor to poverty and remains a significant development challenge. The country is already witnessing climate change and has identified sectors that are especially vulnerable: agriculture/food security, coastal zones and marine ecosystems, water resources, and public health.

The National Council for Sustainable Development, created in 2013, in collaboration with other Ministries, is the key coordinating body to formulate climate change policy in Comoros, based on the national adaptation program of action, the strategic program framework on the natural environment and accelerated growth strategy and Sustainable Development (SCA2D) for 2015-2019. Comoros ratified the Paris Agreement on November 23, 2016 and the associated Nationally Determined Contribution can be found here (in French).
