Country Summary

This page presents high-level information for Mauritius'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 Mauritius's country context and climate is provided following the visualizations.

The Republic of Mauritius, is a small island developing state of about 2,040 km2 in area, comprising the mainland Mauritius, Rodrigues, Agalega, Tromelin, Cargados  Carajos and the Chagos Archipelago. Approximately 25% of the total land area is under forest cover, including about 2% of native forest areas, but the planted forest area is gradually decreasing due to demographic and development pressures. Mauritius faces multi-faceted environmental challenges, such as changes in rainfall patterns both temporally and spatially. Agricultural production may decline in the medium and longer term due to increased rainfall variability. Furthermore, the ecosystem  and natural habitat of fish and other marine species are being rapidly eroded due to adverse impacts of climate change, with  some coral reefs under the threat of extinction, and natural assets, such as beaches deteriorating, posing threat to some $50 million in value from the sector by 2050.

As a Small Island Developing State (SIDS), Mauritius is highly vulnerable to the effects of climate change and its adverse impacts on socio-economic development. According to the latest World Risk Report (2014), Mauritius is ranked as the 14th country with the highest disaster risk and ranked 7th on the list of countries most exposed to natural hazard. Mauritius has a Climate Change Action Plan for addressing these threats. To date, Mauritius has invested significant resources in both adaptation and mitigation measures, despite its limited means. Mauritius has ratified the Paris Agreement and submitted its first Nationally Determined Contribution (NDC) in 2016.
