    Barcelona weather September

    What’s the weather like in Barcelona in September?

    September falls within summer in Barcelona, which means temperatures are high and there’s consistent sunshine on a daily basis. Since the weather begins to cool down in September, it’s a very enjoyable time to visit for less humidity and a cooler climate.

    Geographical influences

    Barcelona weather in September is very warm and sunny with minimal rainfall. The city enjoys a Mediterranean climate from its location in the Costa Brava region on the northeast coast of Spain. Conflicting winds are a regular occurrence because the city is perched on a slightly elevated plateau. This makes weather fluctuations quite common and difficult to predict. However, you’re likely to have plenty of warm sunshine throughout the month with rain being more common towards October.


    Temperatures range from 17°C to 26°C with at least nine to 11 hours of warm sunshine per day. This is slightly less than last month, but you’ll still have plenty of time to explore the city and enjoy your time in Barcelona. Rain is more likely towards the end of the month with 40mm of rainfall spread across nine days. Humidity is comfortable and rarely drops below 57%. Winds travel at around 7mph but are known to reach speeds of up to 14mph on windy days. The sea is warm at 24°C, which is great for swimming or taking part in water sports.

    Holidays in Barcelona in September. What to do and see in Barcelona? What weather to expect?

    Barcelona is one of the largest cities in Spain and one of the most beautiful cities in Europe. Barcelona is a holiday city, posh and dressy, and too big for a week-long trip. It is impossible to see all the sights of Barcelona at one time. But even for a short trip, you will feel how invigorating and inspiring this city is, and what an amazing atmosphere it has!

    You can go to Barcelona whenever you like, because it never gets cold there. But it’s much nicer to explore this city during the warmer months of the year. For example, at the beginning of autumn. In this article, we will talk about what constitutes a holiday in Barcelona in September.

    September is a month with very pleasant temperatures. It is no longer summer heat, but it is still warm in the streets during the day and in the evening. The city is dominated by the Mediterranean climate, so September is quite humid and hot there. The average daily temperature in September in Barcelona is +26…30°C (it almost never happens above +30°C). As a rule, such heat lasts for the first three weeks, and in the last days of autumn, all the same, it makes itself felt with a slight drop in temperatures (but only up to + 23-24 ° C). However, it also happens that just in the last week of September it becomes even hotter than in the middle of the month. In short, during the day in September, below + 20 ° C does not happen.

    Nights in Barcelona at this time are also quite warm – on average +17…20°C, it almost never drops below +15 degrees, so you can sleep with the window open, and party-goers walk until the morning in light clothes (and still, grab a blouse).

    A lot of sunshine is expected in Barcelona in September, but rainfall also happens, although very little: for the whole of September it can rain over Barcelona 3-4 times, and the sky will be cloudy a few more times (no problem). But in September the winds are not as strong as in the rest of the off-season months, and this is also a pleasant fact.

    The sea temperature off the coast of Barcelona at the beginning of September is not that high, but such water cannot be called cold either: on average +24-25°C. Around the last week or in the second half of September, the water temperature drops slightly, literally by a degree, but you can still swim.

    Things to do in Barcelona in September

    Lots of walking! It is quite difficult to capture all the beauty of this city in one go, but you can try. You can explore Barcelona in many ways: by public transport (very convenient, by the way), by tourist buses with audio guides, on foot, etc.

    Of course, there are a lot of historical sights in Barcelona. And most of them are in Old City. It is generally very interesting to walk there, along these narrow streets, past medieval monuments.

    There you will also find Bishop’s Palace (with a small gallery in its courtyard) and Museum of Religious Art , as well as Casa del Ardiaca or House of the Archdeacon . This building is an amazing mixture of architectural styles from several eras. The residence was built in the 16th century on the remains of an older building from the 12th century – hence the mixture of styles.

    You can look into the Museum of the great creator Salvador Dali . His main museum is located in the city of Figueres (in Girona), but Barcelona also has its own exposition of his works. Museum You will not pass by one hundred percent – there is a large egg at the entrance: it means you are in the right place.

    You can go to Horta Labyrinth Park to sit in the Romantic Garden and get lost in the hedge maze. The park is very beautiful and green, and even in the high season (that is, in early September) it is not very crowded there. Entrance is paid, but on Wednesdays and Sundays you can go there without tickets.

    Plaza del Rey is home to the impressive Royal Grand Palace . Once important events were held in it, and in one of the halls the Queen of Spain learned about the discovery of the New World. Take the metro from the palace to Cariera Moncada to reach Picasso Museum is Barcelona’s must-see. The great Spanish painter and sculptor lived and worked in Barcelona, ​​and also here he became close to his future friends Carlos Casajemas and Jaime Sabartes, who later became characters in his paintings. The museum, which is over 50 years old, is housed in the old city palace of the 15th century – the Berenguer d’Aguilar Palace (Palacio de Berenguer d’Aguilar) and is famous for its ancient courtyards.

    It is a must to see some of the creations of the crazy Gaudi with your own eyes. Most of the fantastic works of the Spanish architect were built in Barcelona, ​​where he lived and worked until his death. There are thirteen of these Gaudi buildings in Barcelona, ​​and the most visited of them is Sagrada Familia Expiatory Temple . It is very easy to get to the temple by metro (to the Sagrada Familia station). However, in September you should expect long queues at the entrance to the temple, but it’s worth standing in line, because the unusual interior impresses absolutely everyone. From other popular creations of Gaudí – Casa Batlló (at Passeig de Gracia, 43) and a little further down the street Casa Mila.

    It is also worth driving to Park Güell with interesting “flexible” benches, strange plants, fantastically shaped buildings and “edible” houses. The famous park in the upper part of Barcelona was also designed by Antoni Gaudi in 1900-1914. The park is a combination of gardens and residential areas, and the total area of ​​​​the structure is more than 17 hectares. The once green residential area is now one of the main monuments of Spain, and the park is listed as a UNESCO World Heritage Site.

    Barcelona holidays and festivals in September

    There are many festivals in Barcelona at the beginning of autumn. For example, every year towards the end of September, Barcelona hosts a big street party, Barcelona La Mercè Festival , a celebration in honor of Mare de Daeu de la Merce, the patron saint of Barcelona. The five-day festival officially first took place in 1902. The celebration is impressive: the streets are filled with crowds of people who are just walking or marching during the parade (it is better to leave the car). Plus concerts, tastings, fairs.

    At the beginning of September you can take part in the Cursa Barça , a 10 km run organized by Barcelona Football Club (usually at the Camp Nou stadium).
