Should you visit Barcelona in September? If you’re planning to visit Barcelona during September, you’re probably wondering if it is a good time to come to Barcelona, so I will answer that right away: September is a wonderful time to visit Barcelona! The busy tourist season is drawing to a close, and the locals return from their summer holidays to enjoy the warm weather and celebrate several festivals in the city throughout the month. In this post, I’ll share the best things to do in Barcelona in September, and which festivals you cannot miss when coming to Barcelona in the fall or autumn.
Is September a Good Time to Visit Barcelona?
As I just mentioned, September is one of the best times to visit Barcelona. During August, the city fills with tourists, and the locals head out on their summer vacations, leaving some of my favourite restaurants and bars closed while they are away.
However, in September, as the kids head back to school, the numbers of tourists decrease, and the locals come back home. The weather is perfect for enjoying a range of activities, from sunbathing on the beach to hiking on cooler days, and the festival season is in full swing.
The Advantages of Visiting Barcelona in September
Great Weather
September in Barcelona typically brings warm, sunny days and comfortable evenings – perfect for strolling along the beach or enjoying an outdoor terrace. Humidity drops compared to August, making sightseeing much more pleasant so you can explore the city without dripping in sweat!
Warm Mediterranean Sea
The sea is still invitingly warm, averaging about 24°C, so swimming, paddleboarding, or just lounging by the water is still very much on the cards. The beaches are a little less crowded than in August, so you might find more space to spread out, especially on weekdays or if you head a little further out of the city to beaches around Poble Nou such as Bogatell or Mar Bella.
Slightly Quieter (Mostly!)
While September in Barcelona is certainly not peaceful, it’s noticeably less busy than the height of summer. Attractions like Sagrada Família and Park Güell are still popular, of course, but queues are shorter and the city feels more relaxed overall. You’ll have a better chance of getting into popular restaurants without a booking and can enjoy a more leisurely pace – unless the festivals are happening while you’re in town!
Festival Season is in Full Swing
Speaking of festivals, Barcelona’s cultural calendar is jam-packed in September! La Mercè (around 24 September) is the city’s biggest annual celebration, with parades, live music, castellers (human towers), fire runs, and fireworks filling the streets.
The National Day of Catalonia (Diada) on 11 September is an important day for Catalans, and you’ll see Catalan flags decorating important buildings and squares, with demonstrations and a strong sense of regional pride. You will also find wine and cava festivals, jazz concerts, contemporary art events, and the Cursa de la Mercè running race during September, so you certainly won’t be bored!
Better Prices than Peak Summer
As the high season fades, flights and accommodation can become a bit more affordable – particularly outside of major festival dates. Early booking is still important to get the best deals, but you’re less likely to face the sky-high prices of July and August.
Perfect for Sightseeing and Day Trips
The combination of warm days, cooler evenings, and fewer crowds makes September ideal for exploring both Barcelona and its surroundings. Day trips to places like Montserrat, Sitges, Girona, or the Costa Brava are comfortable without the extreme summer heat.
The Downsides of Visiting Barcelona in September
Festival Crowds and Disruptions
While September is generally quieter than August, the big festivals bring crowds back in force – particularly La Mercè, which draws hundreds of thousands of people. Some streets close for events, public transport gets busy or rerouted, and finding a table at restaurants in the city centre can be difficult during peak times. And that’s not to mention the noise from live music, crowds and fireworks!
Occasional Showers
While the weather in September in Barcelona is generally very good, there could be some showers, especially towards the end of the month. These are usually brief and followed by sunshine, but it’s worth packing a lightweight rain jacket or umbrella so you’re not caught out!
Popular Attractions are Still Busy
Although the summer rush has eased off a bit, you will still need to book in advance for the top sights like La Sagrada Família and Park Güell. The same goes for popular restaurants – while walk-ins are easier now than in August, it’s best to book a table to guarantee you can eat at the time you want.
Potential Political Demonstrations
On Catalonia’s National Day, large political gatherings and demonstrations take place. These are generally peaceful, but some roads will be closed, and there will be large crowds. Check local news or ask your hotel for advice on where to avoid if you don’t want to get caught up in the action – while it can be interesting to see, I usually recommend visitors stay away from large demonstrations like this.
Weather in Barcelona in September
The sticky summer heat is starting to subside, although it is usually still pretty hot in Barcelona during September. There might be a few rainy days, but you can expect most days to be sunny and warm.
Barcelona temperatures in September are usually above 20°C, with an average temperature of 21.5°C (71°F). The hottest days could reach over 26°C (79°F), and the lowest temperatures may dip to around 18°C (65°F). However, with climate change, Barcelona weather is changing so it could be hotter or cooler when you visit.
There is an average of 5 rainy days in Barcelona in the month of September, so it is still worth bringing a light jacket and umbrella just in case! Don’t forget to check the weather forecast before you travel so you have a better idea of what to expect.
What to Pack for a Trip to Barcelona in September
Here are some tips for what to bring and what to wear in Barcelona in September, or you can check out my full Barcelona packing list here:
Lightweight and breathable clothing
It’s still warm in September, so light, loose-fitting clothes made of breathable materials like cotton or linen will help you to feel comfortable in the heat. A mix of T-shirts, shorts, skirts, sundresses, and tank tops is ideal for hot weather, with some longer sleeves and a pair of trousers for cooler days and evenings.
Light Layers
While the days are usually warm, evenings will get cooler, especially later on in the month. Pack a light sweater, cardigan and a jacket for the evenings when temperatures drop or on the occasional rainy days.
Swimwear
It’s usually still warm enough for a dip in the Mediterranean Sea or relaxing by the pool, so having swimwear for a September trip to Barcelona is essential. I’d also recommend a waterproof pouch to keep your phone and keys safe and dry. Don’t leave them unattended on the beach, as they’re likely to be stolen!
Sun Protection
The sun will still be strong in September, even though summer is behind us. Bring sunglasses, a wide-brimmed hat, and sunscreen with a high SPF. Consider packing a lightweight, long-sleeved shirt or a beach cover-up for additional sun protection.
Comfortable Footwear
Barcelona is a city that involves a lot of walking, so pack comfortable shoes like sandals or lightweight sneakers. Make sure to have a pair of shoes suitable for walking on uneven surfaces like cobblestones – high heels can be treacherous, especially in the Old City!
Mosquito Repellent
If you’re prone to mosquito bites like me, it’s a good idea to pack mosquito repellent to protect yourself during the evenings or if you plan to visit parks or outdoor areas at dusk.
Travel Essentials
Don’t forget essential travel essentials like a theft-proof backpack for carrying your belongings, a reusable water bottle to stay hydrated, and a power adapter to charge your electronic devices.
eSIM for Spain
Before you travel to Spain, check if your phone contract includes roaming in Spain, and if you have any data allowance to use while you are travelling. To avoid excess charges for roaming data use, an eSIM is a cheap and useful way to make sure you stay connected, as long as your phone is eSIM compatible.
Airalo eSIMs are super easy to set up, and Airalo sends you email notifications when your eSIM is about to expire so you can top up easily if needed. Their eSIMs for Spain start from $4.50 for 1GB of data which lasts for 7 days and you can even get a free 1GB eSIM to get started!
Travel Documents
Remember to bring your passport, travel insurance, identification, and any other necessary documents. Having a copy of your hotel reservations and emergency contact numbers can be very useful, too, should something go wrong.
The Best Things to Do in Barcelona in September
Book in Advance for Barcelona’s Top Attractions
Even though it’s starting to quiet down after the summer rush, if you want to visit the top attractions in Barcelona you really need to book tickets in advance, otherwise you risk missing out as they can sell out.
I use GetYourGuide to book entry tickets and tours in Barcelona – some recommended tours and attractions in Barcelona you need to book include:
- Sagrada Familia Entry Ticket – don’t miss out, tickets can sell out weeks in advance!
- Sagrada Familia Tour – learn more about Gaudí with a guided tour
- Camp Nou and FC Barcelona Museum – a must for football fans
- Park Güell – a beautiful park with views of the city
- Casa Batlló – one of Gaudí’s most magical buildings
- La Pedrera (Casa Mila) – another of Gaudí’s famous buildings
Enjoy Barcelona’s September Festivals
Barcelona is host to two major festivals during September – La Diada on 11th September, and La Mercé on 24th September.
La Diada Nacional de Catalunya
The National Day of Catalonia is celebrated on the 11th of September, the day that Barcelona finally fell to the armies of the Bourbon king Philip V of Spain during the War of the Spanish Succession in 1714. It is a day of Catalan pride, and the streets are filled with Catalan flags, events, and more recently, marches in favour of Catalan independence.
Celebrations and marches usually centre around the Arc de Triomf (near where the final battle of the siege took place) and Placa Catalunya. It can be wonderful to witness so many people celebrating their nationality in one place, with the red and yellow Catalan flags flying, but be aware that there is a high police presence and try not to be caught up in the demonstrations.
La Mercé
This festival is the annual Festa Major of the city of Barcelona and is in honour of the Roman Catholic feast day of Our Lady of Mercy or La Mare de Déu de la Mercè in Catalan. Shortened to La Mercé, the official Feast Day is the 24th of September, although the celebrations last for 5 days – this year from September 23rd to the 27th.
Everything Catalan is celebrated, from traditional Sardana dancing and human towers known as Castellers, to parading giant models through the streets. You’ll also be able to take part in one of the most fun (and potentially dangerous) activities known as a Correfoc – a Fire Run, involving fireworks in the streets.
There are stages around Barcelona set up for live music, street theatre and fireworks. It is certainly one of the most fun times of the year to be in Barcelona! You can check the official program for the festivities here.
Neighbourhood Festivals
The different neighbourhoods in Barcelona also have smaller festivals that they celebrate every year. Probably the most famous is the Festes de Gràcia which takes place in August, but Poble Nou, La Ribera and Barceloneta have their street festivals in September.
These Festes Majors usually involve community events such as group meals in one of the quieter streets or squares, live music and entertainment and activities for the kids, often with castellers performances, fireworks and traditional dances.
Hit the Beach
September is wonderful beach weather, without as many crowds as the summer season. The Mediterranean Sea is warm and still lovely for swimming, or you can just lounge out on the sand. Generally speaking, the further away from the city you get, the cleaner and quieter the beaches are.
You could also try your hand at SUP or hire a boat to get out on the water. Barcelona is also a nice spot to do some scuba diving, although it isn’t the best place in the Mediterranean for diving, there are some decent places, especially if you go up to the Costa Brava.
The chiringuito beach bars are still open in September, so you can enjoy a drink and some food by the sea as you watch the world go by.
Admire Gaudí’s Work
Gaudí left his mark all over Barcelona, and no Barcelona itinerary is complete without visiting at least one of his famous buildings.
La Sagrada Familia is my personal favourite, and this magnificent cathedral is breathtaking, both inside and out. If you decide to go inside (which is definitely worth it!) make sure you book your tickets in advance to secure tickets on the day you want – they can sell out weeks in advance!
A guided tour is more expensive but will give you more insight into Gaudí’s designs, and you’ll still have plenty of time after the tour to take photographs, as you can stay as long as you like.
Park Güell is another popular choice for enjoying Gaudí’s designs, with the iconic dragon statue and beautiful mosaic terrace with views of Barcelona. Again, book your timed entry slot online to make sure you can get access at the time you want.
Gaudí designed several other buildings in Barcelona as well as these magnificent landmarks. Casa Batlló and La Pedrera are within walking distance of each other on Passeig de Gràcia, and you can buy tickets to explore inside. Both also have rooftop terraces with lovely views, and Casa Batlló has a bar on the terrace where you can get a drink amid Gaudí’s funky chimneys and curved roof.
If you prefer something a bit more out of the ordinary, then try one of Gaudí’s lesser-visited houses. Palau Guell in El Raval, Casa Vicens in Gracia and Bellesguard are all just as fascinating as his more famous works, but much quieter!
Enjoy a Rooftop View
September is a great time to sit outside and enjoy a drink while surveying the Barcelona Skyline. Many bars and hotels have rooftop terraces where you can do just that.
Some of my favourite rooftop bars in Barcelona include the rooftop of the Museu d’Història de Catalunya with a view of Port Vell, Ayre Hotel Rosselló with a splendid view of La Sagrada Familia and Hotel Lamaro (Formerly Hotel Colon) with a view of the Gothic Cathedral.
That said, these beautiful views do come with a premium price tag, so if you’re visiting Barcelona on a budget, then you can simply choose a bar with tables outside in one of the squares and watch the world go by. Some of the best views in Barcelona are of its people!
Go on a Night Tour
If you do find yourself struggling on hot days, save exploring until after dark and join a night tour to experience the most iconic monuments in Barcelona at night, like the Sagrada Familia, the Gothic Cathedral and Casa Batlló, as well as explore Barcelona’s neighbourhoods with a guide.
Explore hidden corners of Barcelona, listen to ghost stories, learn about Barcelona’s dark side, or hop on your bike to see the best of Barcelona by night on two wheels.
Barcelona Night Bike Tour
- Discover the mysterious streets of Barcelona by moonlight
- Explore different neighbourhoods
- Sample cava and see beautiful views of the city at night
- Stop for tapas
- Includes bicycle and helmet hire
- Cost of Tapas isn’t included but you can purchase what you like
Taste Delicious Food in Barcelona
There is excellent food available in Barcelona all year round, but the chance to have dinner outdoors in the late summer and autumn is a true delight. However, before dinner, take a walk through some of the markets in Barcelona to see what is in season in September.
September is the beginning of the mushroom season in Catalonia, and you’ll start to see various kinds of bolets (mushrooms) in the markets as well as other fresh produce. Consider taking a food tour in Barcelona to learn more about Catalan cuisine and taste some of the best food in Barcelona as you go.
If you prefer a more hands-on approach then a paella cooking class is a great way to learn and enjoy the food in Barcelona, and you can take the recipes home with you to enjoy long after your trip has ended. This private farm-to-table cooking class in the countryside outside the city is another wonderful way to learn more about Catalan cuisine and a really special experience.
Otherwise, a stroll around the streets of Barcelona and the many tapas bars and restaurants is a lovely way to spend a warm evening – Carrer Blai in Poble Sec has several pintxo and tapas bars where you can grab a bite and a drink then move on to the next!
Take a Day Trip from Barcelona
If you get tired of the city and want something a bit different, some fabulous day trips from Barcelona are easily accessible by train or car. You can head further up or down the coast to beach resorts like Sitges or Blanes, or head inland to magnificent Montserrat.
September is also a great time to visit Catalonia’s wine regions, as it is the beginning of the grape harvest. The Penedès region is one of the closest to Barcelona and produces most of Catalonia’s cava (the Catalan equivalent of champagne), and you can visit various wineries and cava producers there.
In addition to the usual visits and tastings, many wineries have special events for the Wine Harvest Festival throughout September, although you may need a car to reach some of the more rural wineries.
Sant Sadurní d’Anoia is about an hour away from Barcelona by train and is home to some of the most famous cava producers, such as Freixenet and Cordoniu, as well as lots of smaller producers where you can taste the wines and enjoy a barbecue within walking distance from the train station.

Where to Stay in Barcelona in September
The Gothic Quarter & El Born
The Old City of Barcelona is my favourite area to wander around and explore, and the neighbouring districts of El Born and El Gòtic are both stunning. While they can be extremely busy in summer, September is usually quieter so you can enjoy the pretty streets and hidden squares without the usual crowds.
However, if you’re visiting during La Merce (23rd to 28th September) expect a lot of noise at night or stay somewhere else!

Final Thoughts on Visiting Barcelona in September
For me, September is one of the best times to visit Barcelona, when the weather is still hot, and it is slightly less crowded but there’s still plenty going on. It is much more enjoyable than visiting Barcelona in August, so if you can travel outside of the school holidays and come to Barcelona in September I’m sure you won’t regret it!
