Best time to visit Lisbon
Month-by-month weather, crowd levels and pricing, so you can pick a window that actually suits how you like to travel.
Lisbon's climate, in brief
Lisbon has a Mediterranean climate with a strong Atlantic influence, which in practice means mild, wet winters and hot, dry summers, with a coastal breeze that keeps it noticeably cooler than inland Spain or the Algarve even in August. It's widely considered one of the sunniest capital cities in Europe.
Lisbon by season
Spring (March–May)
Generally considered the best all-round window. Temperatures sit comfortably in the high teens to low 20s°C (mid 60s–70s°F), jacaranda trees bloom purple across the city from May, and crowds are noticeably thinner than summer. Rain is still possible, especially in March.
Summer (June–August)
Hot, dry and busy. Daytime highs regularly reach the high 20s to low 30s°C (mid 80s–90s°F), though the Atlantic breeze and low humidity make it feel more manageable than similarly hot inland cities. This is peak season for both crowds and prices — book accommodation well ahead.
Autumn (September–October)
The other favourite window, arguably even better than spring: summer's warmth lingers, the sea is at its warmest for swimming, and light rain doesn't really arrive until November. Crowds thin out considerably after early September.
Winter (November–February)
Mild by northern European standards — daytime temperatures typically sit around 14–16°C (57–61°F) — but this is Lisbon's wettest stretch, with grey, rainy spells possible for days at a time. Attractions and flights are at their cheapest, and the city itself is far quieter.
So, what's the best time to visit Lisbon?
For most travellers, late April to early June or September to mid-October hit the best balance of warm weather, manageable crowds and reasonable prices. If beach time in nearby Cascais or Costa da Caparica matters to your trip, lean toward June or September, when the Atlantic water is at its warmest. If budget matters more than weather, winter (excluding the Christmas/New Year peak) is genuinely underrated — pack a rain jacket and you'll have the miradouros largely to yourself.
| Month | Typical high | Rain days | Crowds |

Whatever month you visit, layer. Lisbon's coastal breeze means a sunny 24°C afternoon can turn genuinely chilly the moment you're in shade or the evening wind picks up off the Tagus.
