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 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 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 (2015), of which 65.2% live in urban areas. In mainland Portugal, resident population is concentrated along the Atlantic coast. Since 2000 the Portuguese economy has been showing difficulties in ensuring economic growth, which was aggravated in 2008 by the international economic and financial crisis and forced a program of economic and financial adjustment. Since 2013 growth has restored reaching 2.7 % in 2017 (IMF). The climate in mainland Portugal is predominantly influenced by latitude, orography and its proximity to the Atlantic Ocean. Since the mid-70s the average temperature has risen in all regions of Portugal at a rate of approximately 0.3°C per decade. Out of the ten warmest years, seven occurred after 1990, with 1997 being the warmest year. The last four decades have been continuously drier, the driest one being 2001-2010. Portugal submitted its Nationally Determined Contribution (NDC) as an EU Member State in 2015 and its Seventh National Communication in 2017.
