Somersby Out Jazz 2026 Lisbon: Every Sunday, Free Jazz Under the Lisbon Sky

Some of the best things in any city cost nothing and ask very little of you: just your afternoon, your willingness to sit on the grass, and your ears. Somersby Out Jazz is exactly that kind of event. Every Sunday from May through September, a live band sets up in one of the beautiful parks and gardens of the Oeiras municipality, just west of Lisbon, and plays from 17:00 until the sun goes down over the Atlantic. Entry is free. The music is live. The grass is there to lie on. And this is the 20th year of that formula — which tells you everything you need to know about whether it works.

Somersby Out Jazz 2026 runs from May through September, every Sunday afternoon, in the parks and palace gardens of Oeiras — a beautiful, green municipality stretching along the north bank of the Tagus estuary between Lisbon's Belém district and the Cascais coast. Over a summer season, the festival fills these public spaces with jazz, soul, funk, hip-hop, R&B, and world music performed by some of the finest Portuguese musicians and invited international artists, typically drawing more than 60,000 visitors across five months to an event that has never charged a single euro for admission.

Twenty Years of Free Music in Lisbon's Gardens

The Out Jazz festival was founded in 2005 — a single, clear idea that the city's public green spaces deserved to be filled with live music on summer Sundays, and that music should be something a community experiences together rather than an industry product that requires a €100 ticket to access. In its first years, Out Jazz set up in some of central Lisbon's most loved green spaces: Jardim da Estrela (the Victorian garden in the Lapa neighbourhood), Jardim do Campo Grande (the large public park in northern Lisbon), and the Ribeira das Naus waterfront promenade near the Praça do Comércio.

In 2022, the festival moved to the Oeiras municipality — the green, well-resourced coastal municipality west of Lisbon that has invested significantly in its public parks and palace gardens. The move was an immediate success: the combination of Oeiras's extraordinary gardens, the proximity to the Tagus and the Atlantic, and the festival's own reputation brought more than 60,000 visitors across a single season to a series of free Sunday concerts.

In 2025, the festival celebrated its 19th edition — and in 2026, the 20th anniversary arrives with the same commitment that has defined every summer since 2005: free, outdoor, live music every Sunday for five months, with Portuguese musicians at the centre and a genuinely warm, democratic, community-focused atmosphere.

"Over two decades, Somersby Out Jazz has become much more than a festival. It is now a collective ritual lived outdoors, a meeting point where..." — the festival's own description, and a fair one.

The 2026 Season: May Through September, Every Sunday

The 2026 season opens in May and runs every Sunday through late September — roughly 22–24 Sundays of free outdoor concerts across five different parks and gardens as the summer progresses.

Schedule: Every Sunday, 17:00 (5pm) until sunset (approximately 20:30–21:00 in mid-summer Lisbon)

Admission: Free — no tickets, no registration, no queuing for entry

The venues rotate through the season, with each month typically based at a different park or garden across the Oeiras municipality. Based on the established pattern of recent editions, the 2026 rotation is expected to follow a similar structure:

• May: Parque dos Poetas (Poets' Park), Oeiras
• June: Jardins da Quinta Real de Caxias
• July: Parque Urbano de Miraflores
• August and September: Parque Urbano do Jamor and/or Jardins do Palácio Marquês de Pombal and other Oeiras gardens

The exact 2026 venue rotation will be confirmed at outjazz.pt as the season approaches.

The Music: Jazz, Soul, Funk, Hip-Hop, and More

The word "jazz" in the festival's title is both accurate and incomplete. Somersby Out Jazz has always been eclectic at heart — the music ranges from straightforward post-bop jazz quartets to Afro-Portuguese fusion, from acoustic singer-songwriter sets with jazz arrangements to funk, hip-hop, R&B, and electronic music. The consistent thread is quality and a certain kind of warmth: these are musicians who know how to fill a public park with sound that makes people stay and listen.

The standard format for each Sunday:

• An opening DJ set from a Portuguese DJ (typically from 16:30–17:00 as people arrive and settle in)
• A headline live band or ensemble — usually a quartet, quintet, or solo artist with ensemble; performance runs 90 minutes to 2 hours
• Music ends at or around sunset; the DJ typically plays out as the crowd disperses

Sample artists and performances from the 2025 season:

• Desidério Lázaro Quarteto "Oblivion" with DJ João Dinis — a jazz quartet led by one of Portugal's most respected jazz saxophonists, whose "Oblivion" project explores the intersection of jazz and the music of Astor Piazzolla
• Meu Kamba Jazz with DJ Rocky Marsiano — Afro-jazz fusion with deep roots in Angolan musical traditions, brought into conversation with contemporary jazz harmony
• Filipa Franco Quarteto with DJ Rui TrintaEum — a young Portuguese jazz vocalist leading her own quartet through original compositions and interpreted standards

The emphasis on Portuguese jazz is a defining characteristic of the Out Jazz aesthetic. Portugal has a vibrant and internationally underappreciated jazz scene — musicians whose work moves between jazz, Fado, Cape Verdean Morna, Brazilian choro, and contemporary improvised music in ways that are specific to the Portuguese cultural context and genuinely distinct from jazz scenes in France, the UK, or the United States. Out Jazz is one of the few outdoor festivals that makes these musicians its centre of gravity rather than its supporting acts.

The Gardens of Oeiras: What the Venues Are Like

The parks and palace gardens of the Oeiras municipality are among the least-visited and most beautiful public spaces in the Lisbon area. Oeiras is the municipality immediately west of Lisbon along the Tagus riverbank, occupying the stretch of territory between Belém and Cascais — the same coastal axis served by the famous Cascais rail line from Cais do Sodré. For most visitors to Lisbon, Oeiras is a blur between train stops. For those who get off and look around, it reveals a landscape of Atlantic-coast pine woods, Baroque palace gardens, and river views that explain why the Marquês de Pombal built his summer estate here in the 18th century.

The main Out Jazz venues and what they are:

Parque dos Poetas (Poets' Park), Oeiras

The Parque dos Poetas is Oeiras's most popular public park — a large, beautifully landscaped green space that opened in 2002 and is dedicated to Portuguese poetry, with statues and commemorative stones throughout the grounds honouring poets from Fernando Pessoa to Sophia de Mello Breyner Andresen. It covers more than 16 hectares, with lawns, a lake, children's areas, and walking paths that fill with Oeiras residents on weekends even without a festival. As an Out Jazz venue in May — when the trees are in full fresh leaf and the evenings still end before 21:00 — it is one of the most pleasant outdoor concert settings in the greater Lisbon area.

Jardins da Quinta Real de Caxias

The Jardins da Quinta Real de Caxias — the Royal Gardens of Caxias — are a formal Baroque garden complex surrounding a former royal residence in the coastal village of Caxias, overlooking the Tagus estuary. The gardens include terraced lawns, sculpted hedgerows, fountains, and panoramic views over the river toward the Serra de Arrábida on the far bank. In June, when Out Jazz moves here from the Parque dos Poetas, the combination of the Baroque garden setting and live jazz as the Atlantic light fades over the Tagus is one of those genuinely specific Lisbon-area experiences that no other city in Europe can replicate.

Parque Urbano de Miraflores

The Parque Urbano de Miraflores sits in the hilltop town of Miraflores, between the Tagus waterfront and the main Lisbon–Cascais road. It is a large urban park with sports facilities, walking paths, and grassed areas that serve as the July and high-summer Out Jazz home — by July in Lisbon, the evenings are long enough (sunset around 20:45–21:00) that a 17:00 start gives a full three-plus hours of concert and golden-hour atmosphere before the light finally goes.

Parque Urbano do Jamor and Jardins do Palácio Marquês de Pombal

The later-season venues. The Parque Urbano do Jamor is a large sports and green space complex between Oeiras and Cruz Quebrada, with lawns and wooded paths that the Out Jazz crowd adapts to festival use with great success. The Jardins do Palácio Marquês de Pombal — the summer palace gardens of Portugal's most powerful 18th-century statesman — are the most formally historical of all the Out Jazz venues, with the Palace of the Marquês de Pombal (now a cultural centre) as backdrop.

Out Jazz and the Culture of Lisbon Summers

Out Jazz exists within a broader summer culture that makes Lisbon one of the great European cities to be in between June and September. The Lisbon summer is long, reliably sunny, and built around a very specific version of the Portuguese concept of "estar" — a word that doesn't translate well but which means, roughly, "being present, staying, lingering, not rushing."

You hear this in the Fado tradition — the long, slow, emotionally present songs of the Alfama neighbourhood, where time is measured in feeling rather than clock minutes. You see it in the Lisbon café culture, where an espresso can be a two-hour occupation. And you experience it most directly at Out Jazz on a Sunday in July: a park filling slowly from 16:30 onward, families spreading blankets on the grass, couples arriving with bottles of water (no outside drinks allowed, but the on-site bars are there for Somersby cider and other drinks), a DJ easing the crowd into the evening, and then the band beginning to play as the Tagus catches the last of the afternoon light.

This is Lisbon's summer culture in its most organic form, and Out Jazz is one of the longest-running and most beloved expressions of it.

Twenty Summers Later, the Grass Is Still There and So Is the Music

There is something quietly remarkable about a free outdoor jazz festival that reaches its 20th summer still running the same basic idea with which it started: a park, a band, a Sunday afternoon, and everyone welcome. In twenty years, Somersby Out Jazz has given free music to hundreds of thousands of people in Lisbon's parks and gardens, launched the careers of dozens of Portuguese jazz musicians whose first major outdoor audience was a blanket-covered lawn in Oeiras, and created a Sunday afternoon ritual that residents and visitors return to every summer.

May through September 2026. Every Sunday. 17:00 until sunset. Parque dos Poetas, Jardins da Quinta Real de Caxias, Parque Urbano de Miraflores, and more. Free, always. Full programme at outjazz.pt. Catch the Cascais line from Cais do Sodré, get off at Oeiras, and bring a blanket. This is what Lisbon sounds like when it is entirely itself.
