Barcelona Weather in September

Despite being the first month of the autumn season, the weather forecast in Barcelona in September promises relatively hot and sunny conditions. This summer weather is one of the main reasons why so many travellers visit this part of Spain during the month to make the most of the warm temperatures and extended sunshine.

The average temperature in Barcelona in September is 21°C, reaching highs of 26°C which offers perfect weather for spending time at the beach or enjoying outdoor activities around the city and beyond. The average low temperature is 17°C, with this cooler weather happening mostly in the evenings and early mornings as the month draws on.

You can expect an average of eight hours of sunshine a day in Catalonia and Barcelona in September and the UV index will be high throughout the month. Make sure to pack sunscreen and try to stay out of the sun in the middle of the day when it’s really hot, opting for shady areas or attractions with air conditioning.

There is an average of 5 days of rain in September in Catalonia, which is a more common feature of the weather in Barcelona at the end of September. Between 75mm and 100mm of rain falls over the month, but showers are unlikely to last for very long, so you can plan to spend a lot of your time outdoors if you’re visiting the region in September.

Festivals and Events in Barcelona and Catalonia in September

When it comes to ​​what’s on in Barcelona in September, you can look forward to quite an exciting month. There are a couple of annual events that offer brilliant insight into the city and region’s culture, and further afield, Catalonia has several other exciting festivals taking place, which we’ve also included here if you fancy travelling outside of Barcelona.


Grape Harvest Festival, Poboleda

On the first weekend of September each year, the village of Poboleda hosts its annual Grape Harvest Festival to celebrate the area’s winemaking tradition and the old-fashioned techniques that were used in the past. Visitors can not only sample plenty of wine from around the region, but also take part in traditional grape harvesting and grape treading.


FiraTàrrega is an international festival of performing arts that is held every year in Tàrrega, usually over the second weekend of September. The programme aims to offer attendees insight into all the different disciplines involved in the performing arts in the country, with a focus on highlighting how street arts and the performing arts are a tool of social change and education.

Mercat de Música Viva de Vic

The Mercat de Música Viva de Vic is a music festival held in the second week of September in the city of Vic. It’s a four-day festival featuring performances from Catalan and international professionals but also includes workshops, presentations and lectures for musical professionals to expand their knowledge and be inspired by others.

The 11th of September is the National Day of Catalonia, first marked as a national holiday in Catalonia in 1886. It commemorates the day that Catalan troops were defeated in 1714 at the end of the Spanish War of Succession, and is now both a celebration of Catalonian culture and heritage and a chance for pro-independence to voice their opinions.

‘La Diada’ is usually celebrated with parades and demonstrations in larger towns and cities around Catalonia, as well as more festive markets and live entertainment to mark the occasion.

24th September – La Mercè

La Mercè is an annual festival that is held on the 24th of September to celebrate the Patron Saint of Barcelona, Mare de Deu de la Mercè.

The Best Places to Visit in Barcelona in September

Barcelona is a sprawling city, so there are a lot of choices when it comes to deciding where you’re going to visit during your September holiday. Here are some of our top recommendations for the month.

Parc del Laberint d’Horta

Barcelona has several lovely parks dotted around the city that are ideal for lazy afternoons in the September sunshine. But if you’re looking for something a little off the beaten track, the Parc del Laberint d’Horta should be top of your list of places to visit.

Located in the Horta-Guinardó district of the city, the Parc del Laberint d’Horta was designed in 1792 and is famous for being Barcelona’s oldest garden. Spread over 55 hectares in total, nine hectares have been developed into landscaped gardens in a neoclassical style. Visitors can also admire the exterior of the estate owner’s family mansion, which still shows traces of 14th-century architecture.

The highlight of this park is the labyrinth you’ll find in one of the gardens, populated by statues of characters from Greek mythology. It’s the perfect place to come and spend a peaceful afternoon if you want to escape the typical tourist traps of Barcelona.

The Gothic Quarter

Barcelona’s Gothic Quarter is perhaps one of the most famous areas in the city. It’s for this reason that we recommend you pay the neighbourhood a visit if you’re on holiday in September, as you’ll be able to enjoy walking around in the mild weather without getting caught up in too many crowds.

Barrio Gotico is home to a lot of impressive 19th and 20th-century architecture, including the historic Catedral de la Santa Creu i Santa Eulàlia. But there’s plenty to be admired alongside the most impressive feats of architecture, so keep your eyes peeled as you stumble across pretty little squares and admire embellishments and ornate details on the sides of buildings.

If you’re looking for recommendations of what to do in Barcelona in September when you’re staying in the city for a week or more, we definitely recommend that you take at least one day trip. The surrounding region of Catalonia is one of the most scenic and the most interesting parts of the country, and places like the Montserrat mountain range are only a short journey from the city.

The mountains of Montserrat are lovely to explore when the weather in Barcelona in September is dry and mild, but a highlight of this area is the Santa Maria de Montserrat monastery. Some people visit this site as a religious pilgrimage, but whatever your motivations, it’s a stunning location that you can explore either on foot, on a cable car or on a funicular railway.

The Best Things to Do in Barcelona in September

With so many different activities and attractions on offer, it can be hard to decide what to do in Barcelona in September. Here are our top three recommendations.

Spend Time at the Beach

Number one on the list of things to do in Barcelona in September is to spend time at one of the city’s beaches. Nine different beaches cover five kilometres of coastline, offering ample space to enjoy the September sunshine and make the most of the last of the summer weather during your trip.

Barceloneta Beach is the best-known spot and has plenty of facilities and nearby places to eat, but if you’re looking for a quieter atmosphere then Nova Icària Beach or Llevant Beach are great choices. Whether you’re topping up your tan in the afternoon or watching the sunset to finish your day, the average weather in Barcelona in September means that you’re likely to have at least one day with the perfect conditions for the beach.

Go for a Hike

On days when the temperature isn’t quite so high, another great thing to do in Barcelona in September is to take yourself on a hike. The Serra de Collserola Natural Park is the closest national park to the city and is a really popular area for locals and tourists to go to enjoy a green space where they can find some peace and quiet amongst nature.

There are plenty of established hiking trails around the Serra de Collserola Natural Park, as well as the option to travel up the mountain on a ​​funicular railway and then walk back down on foot.

Visit a Vineyard

The grape harvesting season begins in Catalonia in September, which means that this is an excellent time of year to visit a vineyard or try wine tasting. You can either sample the region’s produce at a wine bar in Barcelona or travel outside of the city to see where the product is made.

Alta Alella is one of the closest vineyards to Barcelona and is an ideal place to plan a wine-tasting day trip. If you’re willing to travel further, Penedes is world-famous for its Cava, Conca de Barbera is more of an off-the-beaten-track destination perfect for real wine enthusiasts, and the Priorat region is best known for its red varieties.
