About Portugal

Portugal packs Atlantic beaches, hilltop castles and industrial-age cities into a narrow strip of Iberia, with the Azores and Madeira far out in the ocean. Lisbon and Porto anchor the coast, the Douro valley terraces wine, and the Alentejo and Algarve cover the sunny south. Spring and early autumn are the most comfortable seasons for cities and walking; summer fills the beaches, while winter is mild in the south and wetter in the north.

How are the Portugal travel scores calculated?
Every city is rated 0-10 per month using ERA5 climate normals - temperature, precipitation, humidity, daylight, and days with 6+ hours of sunshine.

Climate data: Open-Meteo ERA5 historical archive, the five most recent complete years (2021–2025). Scores are monthly averages for that window, not forecasts, and short-window precipitation can differ from longer-term normals. “Sunny days” count days with at least 6 hours of measured sunshine — they are not dry days.
