Portugal’s Mediterranean climate brings hot, dry summers and mild, wet winters, making late spring and early autumn the sweet spot for comfortable sightseeing. For current conditions, see the live forecast above.
What is Portugal’s climate like throughout the year?
Summer (June–September) is reliably sunny, with temperatures often reaching 30°C in the Algarve and Lisbon. Winters are cooler and wetter, especially in the north, but Faro and the Algarve coast stay around 12–16°C. The sea warms to 22°C by August. Monthly averages show July and August as the hottest, while November and December bring the most rain. For a 14-day or 30-day outlook, the live forecast above gives the most accurate update, and many travellers check UK conditions before booking to compare the difference.
Which part of Portugal has the best weather?
The southern Algarve, including Albufeira and Faro, enjoys the most sunshine – over 3,000 hours a year – and the mildest winters. Central Portugal (Lisbon) has similar summers but slightly more rain. The north, around Porto, is greener and cooler. If you’re after a beach holiday, the Algarve is the most reliable pick for year-round warmth. For a quick comparison, our 10-day UK forecast can help you decide when to escape the British chill.
Does it rain a lot in Portugal in winter?
Winter rain is common, especially north of Lisbon. The Algarve and Faro still see 6–8 rainy days per month from December to February, but many days remain bright and pleasant for exploring.
Is the Algarve warm enough for swimming in May?
Sea temperatures in May are around 17–18°C, which feels cool for most. By June the water reaches 20°C, so May is better for sunbathing and coastal walks than serious swimming.
