Best Time to Visit Lisbon
Portugal
Lisbon enjoys one of Europe's most pleasant climates year-round. But timing your visit strategically can mean the difference between perfect golden light and summer crowds that turn the trams into sardine cans.
Best Months
March-May, September-October
Good Months
June, November
Consider Avoiding
July-August (overcrowded, 35°C+)
Season by Season
Spring (March-May)
The ideal window. Temperatures of 16-22°C, jacaranda trees in bloom (late April-May), uncrowded miradouros (viewpoints), and restaurant terraces that are pleasant rather than scorching. Hotel prices are 30% below summer.
Summer (June-August)
Hot (30-38°C), crowded, and expensive. The Santos parties and beach excursions to Cascais and Comporta are the upside. But the historic centre becomes a tourist bottleneck, and Tram 28 is unusable due to queues.
Autumn (September-October)
Lisbon's second golden window. Temperatures drop to a comfortable 22-28°C, the sea is still warm enough for swimming, and the summer crowds have departed. Late September particularly rewards with golden light and cultural events.
Winter (November-February)
Mild by European standards (10-15°C) with occasional rain. Christmas in Lisbon is charming — decorations throughout Chiado and Baixa. Hotel prices are at their lowest. The city feels genuinely local rather than touristic.
