Summer in Lisbon

Typical temperatures for summer are between 25ºC and 30°C (77°F to 86°F), with clear skies and lots of sun. Summer is the perfect time to go to one of the great beaches around Lisbon or sunbathe on the bank of the River Tejo. Expect some crowded shores.

Occasionally, temperatures exceed 35°C (95ºF), due to African air masses that originate heat waves over long periods (a week or so) of excessively hot weather. Be sure to wear a hat, sunglasses and sunscreen.

Summer is the peak season in Lisbon with several festivals and events all over the city. One of the most famous is the celebration of the Patron Saints (Festas dos Santos Populares) in the historic districts, with arraiais, street parties with sardine-feasting, drinking and dancing.

Spring and Autumn in Lisbon

Spring and autumn are good seasons to visit Lisbon, with average daytime temperatures from 20ºC to 25ºC (68ºF to 77°F).

Spring, from March to May, is mild, with some periods of showers or rain, which become rare by the end of April.

From mid-September to November, the weather is still warm and sometimes sunny, gradually becoming colder and rainy as November approaches. Be sure to take an umbrella and a raincoat if you visit Lisbon during this time of the year.

During these seasons, the city is less touristy, and there are fewer crowds when visiting monuments or eating at trendy restaurants.

Winter in Lisbon

The winter months, from December to mid-March, are warm when compared to most European countries because of the influence of the Atlantic Ocean. The average temperature is 12ºC (54ºF). Daytime temperatures are generally comfortable, around 16ºC (61ºF), but at night they can lower, going down to 5ºC (41ºF). Freezing days are rare in Lisbon, and snow is almost nonexistent.

Hotel rates and airline tickets are cheapest in this season. There are less tourists, and attractions can be visited without enduring a long wait.

Lisbon Weather in a Nutshell

  • Summer is expensive, hot and crowded with tourists, not recommended unless you go to the beach.
  • Winter is chillier and the days are smaller; however, the hotel and airline prices are lowest and sights are yours to enjoy, no crowds around.
  • Spring is sunny and nice. Hotel and airline tickets have acceptable prices, but tickets sell out quickly and budget hotels book up fast.
  • Autumn can be rainy, and there may even be a few days of heavy rain, but other than that the weather is fine with comfortable temperatures. As in spring, prices are decent, hotels may be less booked, and attractions can be visited at your own rhythm.
