Average daytime temperature in °C. Figures are for Portugal.

Lisboa (Lisbon) is Portugal's sun-drenched capital, a city of seven hills overlooking the wide mouth of the Tagus River where it meets the Atlantic. One of Europe's oldest and most atmospheric capitals, Lisbon blends Moorish alleyways, Manueline monasteries, baroque palaces, and cutting-edge contemporary culture into a tapestry of faded grandeur and vibrant renewal. The city's golden Age of Discoveries legacy is visible in every azulejo-tiled facade, and audible in the mournful strains of fado drifting from Alfama's cobbled lanes.

The Lisbon Region has a warm Mediterranean climate (Köppen Csa) with hot, dry summers and mild, wet winters. The city receives approximately 2,800 hours of sunshine per year — among the most of any European capital. Atlantic breezes from the west moderate summer heat, especially at coastal locations like Cascais and Sintra. Winter temperatures rarely drop below 8°C (46°F) and snow is virtually unknown.
