Portugal captivates visitors with its dramatic Atlantic coastline, historic cities adorned with colorful azulejo tiles, and a rich maritime heritage. From the vibrant streets of Lisbon to the port wine cellars of Porto, ancient castles of Sintra to the golden beaches of the Algarve, this sun-drenched country offers an irresistible blend of culture, cuisine, and coastal beauty.
Portugal has a temperate Mediterranean climate with warm, dry summers and mild, rainy winters. The south (Algarve) is the warmest and driest region, receiving over 3,000 hours of sunshine annually — the most in Europe. Lisbon enjoys mild year-round temperatures rarely dropping below 8°C in winter or exceeding 35°C in summer. The north (Porto, Minho) is cooler and rainier, with Atlantic influence bringing green landscapes. The Azores and Madeira archipelagos have subtropical oceanic climates with mild temperatures year-round.
