Best Time to Visit Portugal: Month-by-Month Guide
The best time to visit Portugal is spring (April–June) and early autumn (September–October) — warm and uncrowded, with a swimmable Algarve. Portugal's mild climate suits shoulder seasons.
Quick answer
The best time to visit Portugal is spring (April to June) and early autumn (September to October) — warm, sunny days, a swimmable Algarve and far fewer crowds than the July–August peak. Portugal has one of Europe’s mildest climates, which makes its shoulder seasons especially rewarding and even winter viable: the Algarve stays relatively warm and Madeira is warm year-round, while Lisbon and Porto are cheap and atmospheric in the off-season.
Key takeaways
- Best overall: April–June and September–October — warm, uncrowded, and swimmable in the south.
- Peak: July–August is hot and busy on the Algarve, with the highest prices.
- Winter sun: the Algarve stays mild and Madeira is warm all year — good low-season value.
- Cities: Lisbon and Porto are rewarding year-round; spring and autumn are most comfortable.
- Portugal is generally good value by Western-European standards, especially off-peak.
The short answer
Thanks to a famously mild climate, Portugal’s shoulder seasons deliver near-summer conditions without the summer crowds — you get warm, sunny days and a swimmable coast in spring and autumn, at lower prices. Even winter is a genuine option in the south and on Madeira.

Season by season
Spring (March–June)
Lovely across the country — Lisbon and Porto are comfortable for walking, the countryside is green and flowering, and the Algarve warms up nicely by late spring, with the sea swimmable by June. Crowds and prices sit well below peak, making spring a superb time to visit.
Summer (July–August)
The Algarve is in full swing — sunny, hot and crowded, with the year’s highest prices. Inland (the Alentejo, the Douro) can get very hot, while Lisbon and Porto are busy but manageable. Great for a beach holiday if you book ahead and accept the crowds.
Autumn (September–October)
Often the sweet spot: warm sea, sunny days, thinning crowds and lower prices. September is excellent on the Algarve, and it’s harvest season in the Douro wine valley — a beautiful time to visit Porto and the river.
Winter (November–March)
Cooler and wetter, but mild by European standards. The Algarve stays relatively warm and is a quiet, inexpensive winter-sun option; Lisbon and Porto are atmospheric and cheap in the off-season with occasional rain; and Madeira, out in the Atlantic, is warm year-round.
Where you go changes the ideal month
For a beach trip, target late spring through early autumn on the Algarve. For city breaks (Lisbon, Porto), spring and autumn are most comfortable but any season works. For winter warmth, head to Madeira or the southern coast.
When it’s cheapest and when to avoid
Best value with good weather is May–June and September. The priciest, busiest time is July–August on the Algarve. Winter is cheapest and, in the south and Madeira, still mild.
How long to go
A week comfortably covers Lisbon, Porto and a taste of another region; add the Algarve or the Douro for 10 days. See our Lisbon guide for city planning.
Weather and temperatures in detail
Portugal is mild and sunny. Lisbon enjoys gentle winters around 8–15°C (46–59°F) and warm summers of 20–28°C (68–82°F); the Algarve is warmer and driest, while the interior (the Alentejo) gets hotter in summer. The Atlantic keeps the coast fresher than the Mediterranean — even in summer the sea is refreshing rather than warm. Out in the ocean, Madeira holds a subtropical 17–25°C (63–77°F) year-round.
Festivals and events worth timing your trip around
June is festival month: the Santos Populares, with Lisbon’s Santo António (12–13 June) and Porto’s exuberant São João (23–24 June), fill the streets with grilled sardines, music and celebration — a wonderful, very local time to visit. Autumn brings the Douro wine harvest, and Carnival and Easter add spring colour. These are great to time around, with the June saints’ festivals a particular highlight.
What to pack
- Spring/autumn: layers and a light jacket; swimwear for the south.
- Summer: sun protection and light clothing; sturdy shoes for Lisbon’s hills.
- Winter: a warm layer and a rain jacket; beachwear still useful for Madeira.
