🇵🇹Portugal

Portugal extends from 37° to 42°N on the western edge of the Iberian Peninsula (92,090 km²), plus the Atlantic archipelagos of Madeira and the Azores. The mainland spans dramatic climatic gradients: temperate maritime Csb in the green Minho northwest with Braga and Porto receiving over 1,400 mm annually; hot-summer Mediterranean Csa across the interior Alentejo, the Douro Valley, and southern Algarve with Lisbon, Évora, and Faro; cool-summer Mediterranean Csb on the central Atlantic coast around Coimbra; and semi-arid BSk enclaves inland in Trás-os-Montes.

The Serra da Estrela rises to 1,993 m at Torre—continental Portugal's highest point—sustaining the country's only ski area and occasional winter snow. Madeira (subtropical oceanic Cfb) and the Azores (fully oceanic Cfb) lie 1,000 km and 1,500 km offshore, experiencing mild year-round temperatures with heavy rainfall.

Lisbon averages 11°C in January and 24°C in July with 770 mm concentrated in the October–April rainy season, though summers remain completely dry. Porto in the humid north records 9°C and 20°C with 1,220 mm. Faro on the southern Algarve coast shows 12°C and 24°C with only 500 mm—the driest region.

Évora in the interior Alentejo endures 8°C winter lows and 26°C July averages with summer maxima frequently exceeding 40°C; the national temperature record of 47.0°C was set at Pinhão in the Douro Valley on 14 July 2022. Funchal (Madeira) remains subtropical at 16°C and 22°C with 640 mm, while Ponta Delgada (Azores) stays mild at 14°C and 22°C with 1,020 mm.

Portugal has experienced significant climate events including the June 2017 Pedrógão Grande wildfire (66 deaths), October 2017 fires (49 deaths), the 2003 heatwave, the 2017 fire season (540,000 hectares), the July 2022 heatwave record, the 2017–2024 drought, and declining Tagus and Douro river flows.
