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 in the map below use observed, historical data (sourced from the Climate Research Unit [CRU]) and are derived by applying the Köppen-Geiger climate classification methodology. This classification divides climate into five primary climate groups, which are divided based on seasonal precipitation and temperature patterns. The five primary 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). It is important to understand the different climate contexts that exist within a country as well as the surrounding region when analyzing current climates and projected change. 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 located in the South West Indian Ocean (SWIO) with a population of about 1.3 million people (2020). The State of Mauritius includes Mauritius, Rodrigues, Agalega, Tromelin, Cargados Carajos and the Chagos Archipelago, including Diego Garcia and several islets around these islands. Its total area is about 2,040 km2 with mainland Mauritius occupying about 1,865 square kilometers and Rodrigues about 108 square kilometers. Approximately 25% of the total land area is under forestry cover, including about 2% of native forest areas.

The main economic sectors are tourism, financial services, retail trade, and the Information and Communication Technology (ICT). Mauritius recently became a High-Income Country (July 2020). Mauritius is highly vulnerable to the impacts from intense cyclones, abnormal tidal surges, prolonged droughts, flash floods, and increase of sea temperature.
