Lisbon in September – Weather and Events

As summer approaches autumn, September is the perfect time to explore Lisbon, its monuments and history. It’s also a fun time of year to enjoy a fado show, and head out on a walking tour.

Autumn offers warm temperatures and fewer crowds in Lisbon. Hotel rates start to drop. It’s still a good month to go to the beach though. It’s always sunny, and the water is relatively warm.
