Country Summary

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

Portugal comprises three different areas: the mainland in the European Continent (the Mainland) and two archipelagos in the Atlantic Ocean, the Archipelago of the Azores and the Archipelago of Madeira. Portugal’s territory has a total area of 92,226 km2 and a coastline of 2,601 km. Portugal’s population is estimated at 10.3 million (2020), of which 65.2% live in urban areas. In mainland Portugal, the resident population is concentrated along the Atlantic coast. Portugal is vulnerable to the climate change impacts from extreme events associated to lack (droughts) or excess (floods) of rainfall and heat waves. Sea level rise also is a threat to Portugal’s coastline where significant amount of its population lives.
