Summer in Lisbon
Although the temperatures can be high in July and August, the wind from the Atlantic Ocean provides cooling. June is a fun month to visit Lisbon to experience the month-long festival in the city – music, sardines and endless parties in the streets of Alfama. It’s an experience of a lifetime.
In addition, midsummer is a perfect time for a beach vacation, as the water off the coast has warmed up by then. Between June and August, there’s an average of 10 hours of sunshine daily. Expect crowds during Summer, especially at the popular sights in Lisbon like the Belem Tower.
Also, remember that Lisbon is a very hilly city, which becomes extremely exhausting to navigate during the hot temperatures from June to August.
