September is the most popular time to visit Lisbon City Centre, as the summer crowds start to dissipate while the warm weather lingers. This transition month allows travellers to enjoy the vibrant city atmosphere without the bustling high tourist season that peaks from July to September. With average temperatures settling comfortably in the low 20s Celsius, it's an ideal period for outdoor activities, leisurely strolls through historic neighbourhoods, and sightseeing.
During this time, visitors can explore the charming streets of Alfama, take in the stunning views from São Jorge Castle, and savour delicious cuisine at outdoor cafes without feeling rushed. September also offers a variety of cultural events and festivals, filling the city with music and excitement, making it a delightful experience for those seeking an immersive holiday.
For those looking for more economical options, November is a fantastic choice. While the weather is cooler, averaging around 15°C, the city is much quieter, allowing for a more relaxed exploration of museums and local attractions. It's an excellent time to enjoy Lisbon's rich history and architecture at a leisurely pace, without the long queues typical of the peak season.
