As students get back to school, the basic crowds thin out a little. If you enjoy beach weather and want to pack light and, September is the monty for you!

Why you should visit Barcelona in September

  • Crowds are less than in September, so it’s considered the shoulder season. Personally, the ideal time to come is mid-September to the end of September. Kids will definitely be in school.
  • La Merce is the most important festival in Barcelona. It celebrates our patron saint of the city, the Virgin Mary, under one of her special titles “Our Lady of Mercy”. Nowadays, it’s a secular holiday full of concerts, human castles (castellers), fire runs (correfocs), workshops, theater, and more!
  • It’s a great time to hit the beach in September in Barcelona. Crowds will be thinned out, and it’s still hot enough for you to strip down to your swimsuit!
  • It’s also a fantastic time to enjoy outdoor activities, like biking or sailing. Check out my post on taking a bike tour with Steel Donkeys!

Barcelona weather in September

The weather in Barcelona in September is typically sunny and hot. It is one of the warmest months of the year, with an average high temperature of around 29°C (84°F) and an average low temperature of around 22°C (72°F). During the day, it can feel quite hot and humid, which can make it uncomfortable to be outside for long periods of time. However, there is usually a sea breeze that helps to cool things down in the evening.

Remember to stay hydrated and wear sunscreen if you are spending time outdoors in Barcelona in September. Additionally, it’s probably a good idea plan your activities for early in the morning or later in the afternoon, when the temperatures are cooler.

Overall, if you enjoy warm weather and sunshine, September can be a great time to visit Barcelona. Just be prepared for the heat and make sure to take necessary precautions to stay safe and comfortable.

Tips for dressing appropriate in September in Barcelona

If you are visiting Barcelona in September, it is important to dress appropriately for the hot and sunny weather. Here are some tips for what to wear:

  1. Wear light, breathable fabrics. Choose lightweight, breathable fabrics like cotton or linen that will keep you cool and comfortable in the heat.
  2. If you head to the beach, protect yourself from the strong sun by wearing a wide-brimmed hat, sunglasses, and sunscreen.
  3. Barcelona is a walkable city, so make sure to bring comfortable shoes that can handle the heat and the walking. Sandals, sneakers, and breathable shoes are all good options.
  4. Wear light layers. While it is hot during the day, the evenings can be a little cooler. Personally, I avoid wear jeans. They are too thick. But in September, you will not have to bring a sweater or jacket. It is hot all the time!
  5. Dress modestly. While Barcelona is a cosmopolitan and pretty liberal city, it is still respectful to dress modestly when visiting religious sites like churches or cathedrals. Bring a shawl or cover-up to wear over shorts or tank tops if needed.

La Diada: September 11, 2023. ‘mericans say September 11th, Catalans say National Day of Catalonia. La Diada commemorates a day in 1714 when Barcelona city fell to Spanish troops. The past few years, the significance of La Diada has intensified due to the ongoing political tension with Catalan independence. Expect to see mostly peaceful marches and lots of red-and-yellow Catalan flags. Shops and restaurants are closed.

Festa Major de La Barceloneta (La Barceloneta Festival). TBD. Also called the Festa Major de Sant Miquel, this neighborhood festival is held in the seaside neighborhood of La Barceloneta. It has gegants, a parade of cannons (that shoot candy!), decorated streets, correfocs, and dancing of sardanas. 

Festa de La Mercè. Around September 24 (TBD). A citywide festival spanning a few days, this is the largest (and FREE!) festival in Barcelona. It honors the other patron saint of Barcelona, the Lady of Mercy. There are 600 activities spread throughout Plaça Sant Jaume, La Barceloneta, Plaça Catalunya, Passeig de Gracia, Park Ciutadella, and all the neighborhoods. It includes concerts (the BAM festival is included here), gegants, workshops, castellerscorrefocs, theater, kids’ activities, performances, and so much more!
