August is Lisbon's hottest month: 20–32°C, sunrise at 6:50, sunset at 20:35. Many locals leave for holidays, so some neighbourhood restaurants close, but the city remains lively with Jazz em Agosto, open-air festivals, and packed beaches. Out Jazz concerts and Festas do Mar in Cascais add to the summer rhythm. Check for restaurant closures before visiting. It's a month for sun, music, and late-night walks along the Tagus.
Pro tips for visiting Lisbon in August
• Check restaurant opening hours before visiting, as many local tascas close for August holidays—call ahead or use online listings. • Go early to Jazz em Agosto concerts at Gulbenkian Foundation for the best lawn spots—bring a blanket for comfort. • Head to beaches like Costa da Caparica before 10am to avoid traffic and secure a good place on the sand. • Reserve accommodation near the coast if you plan to spend most days at the beach—city hotels fill with tourists. • Avoid driving in and out of Lisbon on weekends, as traffic to the beaches and resorts is heavy. • Choose open-air attractions and evening events to beat the daytime heat—parks and riverside walks are best after sunset. • Skip central sightseeing midday; museums and churches offer cool retreats from the sun. • Reserve tickets for Festas do Mar in Cascais in advance, as this maritime festival draws big crowds in late August.
