Lisbon's Mediterranean climate draws many tourists in August, though the days are hot and most locals are away on their own vacations. The early summer months (June, July) are milder and very festive: popular feasts draw crowds, streets filled with the smell of sardines, bars and restaurants remain open late into the night, and you'll find live music in gardens and neighborhood squares. Take advantage of the long days to spend an afternoon enjoying the view from one of the city's many terraces. September is quieter, and you'll also find wonderful natural light, changing colors, and plenty of events.
