Barcelona in October: Autumn Festivals, Mild Weather & Fewer Crowds
October is a quieter, milder version of Barcelona: the summer crowds have thinned, queues at the big sights drop, and daytime highs settle into a comfortable 18-24°C. It's also a busy month for events, from Sitges' film festival to Halloween and the Catalan chestnut festival Castanyada.
October weather in Barcelona
Daytime temperatures typically run 18-24°C, with evenings cooling to around 13-17°C. It's generally dry, though showers do happen, so it's worth packing a small umbrella or light raincoat if you're walking a lot.
What to wear in October
Layers work best: lightweight tops or long-sleeve shirts for the day, a sweater or light jacket for evenings, and comfortable walking shoes. Bring sunglasses and sunscreen for sunnier days, and a swimsuit if you want a dip, though the sea is cooler than in summer by this point.
Festivals and events in October
Sitges Film Festival (October 8-18, 2026)
Sitges, about 40 minutes from Barcelona, hosts one of the world's best-known festivals for fantasy and horror film, running since 1968. The 2026 edition runs October 8-18, with screenings ranging from classics to new releases, plus workshops, masterclasses, and awards. Book accommodation and festival passes early, since the town fills up fast.
Halloween in Barcelona (October 31)
The Gothic Quarter's narrow medieval streets make an obvious setting for Halloween. A few ways to mark it:
- Bars and clubs across the city run Halloween parties with live music and DJs.
- Several companies run ghost tours that dig into Barcelona's darker history.
- Look out for pop-up haunted houses and horror experiences around the city.
BAUM Fest (October 2-4, 2026)
BAUM Fest is Barcelona's tattoo expo at Fira de Barcelona, with tattoo artists from around the world, plus contests, live music, DJ sets, and a marketplace for supplies and clothing.
Barcelona Oktoberfest (October 2-19, 2026)
Barcelona's Oktoberfest has moved to Fira Barcelona - Gran Via (Hall 4) after years at Montjuïc. Expect a large tent, German beer, bratwurst, pretzels, and live Bavarian bands and DJs. Entry is free; food and drinks are paid separately, and evening sessions on Fridays, Saturdays, and the day before public holidays carry a small cover charge.
48H Open House Barcelona (October 25-26, 2026)
On the last weekend of October, Barcelona opens the doors of buildings normally closed to the public, free of charge: a chance to see inside places like Casa Milà, Casa Batlló, Park Güell, and the Hospital de la Santa Creu i Sant Pau, alongside dozens of other buildings across the city.
Castanyada (October 31 / November 1)
Castanyada is a Catalan autumn tradition marking the harvest and All Saints' Day. The food is the point: roasted chestnuts, roasted sweet potatoes, and panellets (small marzipan cakes), often with a glass of sweet Moscatell. You'll see it in bakeries and street stalls across the city on October 31 and November 1.
Things to Do in Barcelona in October
Hop-on hop-off bus
With milder weather, the tourist bus is a decent way to get an overview of the city's layout. Commentary runs in multiple languages, and you can hop off at Park Güell, the Sagrada Família, and other stops along the route.
Churros con chocolate
Carrer de Petritxol is the place for churros: fried dough dipped in thick hot chocolate, and a good way to warm up after an October evening out.
Bike tour
October's temperatures make cycling comfortable again. A route through the Gothic Quarter, along the seafront, and up towards Montjuïc covers a lot of the city without much effort.
Poble Espanyol
Built for the 1929 International Exposition, this open-air museum recreates over 100 buildings from across Spain's regions, with craft workshops and restaurants tucked into the streets.
Joan Miró Foundation
The Fundació Joan Miró holds a large collection of his paintings, sculptures, and drawings on Montjuïc, and is a good way to spend an afternoon if you want a break from Gaudí.
Montjuïc cable car
The cable car up to Montjuïc Castle gives wide views over the city and the harbour, and on a clear October day, visibility is usually better than in the summer haze.
MACBA
Barcelona's contemporary art museum runs a rotating programme of exhibitions, and its white Richard Meier-designed building is itself a draw for architecture fans.
Santa Maria del Mar
Known as the "Cathedral of the Sea," this Gothic church in La Ribera was built between 1329 and 1383. The tall columns and open interior are some of the best examples of pure Catalan Gothic, and unlike the Cathedral, it's rarely crowded.
Barcelona nightlife
Cooler evenings make October a good month for going out: beachfront clubs in Barceloneta, cocktail bars in the Eixample, and live music venues in Gràcia all pick up as the heat fades.
