Country Summary

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

Yemen is a Middle Eastern country located at the southern end of the Arabian Peninsula. Yemen’s economy has previously been dominated by the oil sector, but declining oil revenues and resource depletion have rendered it necessary for the government to scale up its efforts to spur non-oil growth and create jobs in sectors such as agriculture, fisheries, natural gas, urban manufacturing, services, and the financial sector. The country has a predominantly rural and rapidly growing population of approximately 29.8 million (2020) people, with a 38% poverty rate. 

For years, Yemen has been the poorest country in the Middle East and North Africa and it is now also suffering the worst humanitarian crisis in the world. Yemen is a food-insecure nation that is highly dependent on staple food imports. Water resources are scarce and rapid groundwater depletion as well as inadequate infrastructure, pose challenges to sustainable development in the country, along with the expected impacts of climate change. A range of other socioeconomic and institutional factors hamper Yemen’s ability to respond to current and projected changes in climate.
