6 Things You Need to Do When Visiting Lisbon in September

Lisbon in September is that time of year when school’s in but summer is not quite out yet. Summer lingers well into the month, offering warm days and mild evenings, perfect for al fresco drinks and spontaneous weekend trips to the beach. The light still lasts long enough to soak in the city’s charm, and it won’t start feeling like fall for another month or so. 

September in Lisbon also brings a calmer atmosphere—tourist crowds begin to thin out, and Lisboetas return to their daily routines. If there’s ever a sweet spot between tourist season and authentic city life, you’ll find it here. Here’s what’s on our agenda this month.

Get spooked at MotelX

During the second week of September, horror movie fans flock to Cinema São Jorge for MotelX, Lisbon’s premier horror film festival. This is the event they’ve been waiting for all year. For one spine-chilling week, the silver screen comes alive with the latest horror films, short features, and eerie documentaries.

It’s a showcase of rising stars in the genre, with plenty of opportunities for audience members to discover a new favorite director or film. MotelX also pays homage to the classics, with special retrospective sessions. Every year, horror aficionados can expect screenings of cult hits.

In 2019, for example, they featured “Alien” and “Friday the 13th.” No matter your taste in terror, this festival promises thrills and chills in one of Lisbon’s most iconic cinemas.

Experience fado at Santa Casa Alfama

Fado is Lisbon’s most beloved music genre, steeped in emotion and tradition. The Santa Casa Alfama festival, held at the end of September, honors this soulful music in the city’s most iconic neighborhood.

Since its debut in 2013, the festival has aimed to bring fado to a broader audience, with performances taking place across Alfama, from churches and museums to outdoor stages.

For two nights, the narrow streets of Alfama are filled with the haunting sounds of guitars and voices, as both seasoned and up-and-coming fado singers pour their hearts into their performances. After the music, take time to explore Alfama’s labyrinth of streets and settle in for dinner at one of the many cozy, traditional restaurants that dot the area.

Dance in the park at a music festival

Music lovers, this one’s for you. The Lisb-On festival is one of Lisbon’s biggest summer parties, held every September in the lush surroundings of Parque Eduardo VII. Over three days, this festival brings together electronic music lovers from all over, with DJ sets and live performances running from 2 p.m. to midnight.

Lisb-On is more than just a concert—it’s a laid-back social gathering. Grab a blanket and picnic with friends during the afternoon, or dance the night away as the park transforms into an open-air dance floor.

And if you’re traveling with family, don’t worry—kids between ages 3–14 get in for free, making it an all-ages event.

Immerse yourself in Portuguese heritage

September in Lisbon isn’t just about festivals—it’s also a great time to dive into the city’s rich history. The European Heritage Days, held every year in September, offer a special opportunity to discover Portugal’s cultural treasures.

During these three days, some of Lisbon’s most famous monuments and historical sites open their doors for free, with guided tours and special events.

It’s a rare chance to go beyond the usual tourist attractions, exploring hidden corners of the city’s history. From night tours in museums to access to never-before-seen collections, European Heritage Days provide a deep dive into Portuguese culture and heritage.

Grab a bite: What to eat in Lisbon in September

All these energy-packed events in September mean you’ll need to recharge on the go. Although we’re fond of sitting down for meals on most occasions in Portugal, that doesn’t stop us from switching the long sit-down lunch for a quick bite at a food truck during a festival. 

For something quick and satisfying, grab a bifana:

• A simple but delicious pork sandwich that’s a staple of Portuguese street food. Don’t underestimate the humble bifana, though. The secret lies in the slow-cooked, marinated pork and the perfect ratio of mustard (just a dab will do).

For a more leisurely meal, late summer in Lisbon calls for outdoor dining. Take advantage of the warm evenings by finding a restaurant with a view, where you can savor grilled fish, drizzled with olive oil, and sip on a glass of chilled vinho verde as you watch the sunset over the city.

As summer winds down, you’ll still find plenty of seasonal fruits and vegetables at the markets—don’t miss the chance to try some late-season figs or a plate of freshly grilled sardines.

Take a day trip: Beaches and beyond

While Lisbon itself is brimming with things to do, September is also the perfect time to venture beyond the city for a day trip. The nearby beaches of Cascais and Costa da Caparica are just a short drive or train ride away and still bask in summer warmth. Spend the day sunbathing or surfing before heading back to the city for a late dinner.

For a more historical excursion, head to Sintra, a fairytale town just outside of Lisbon, where you can explore colorful palaces and winding mountain paths. September’s milder temperatures make it an ideal time to wander through the gardens of the Quinta da Regaleira or hike up to the Moorish Castle.

In Lisbon, September offers the best of both worlds—fewer crowds, authentic local life, and endless opportunities to experience the city’s cultural, culinary, and natural treasures. Whether you’re a film buff, a foodie, a history lover, or just someone who enjoys a good sunset, there’s something for everyone in the Portuguese capital this month.
