June wins for most visitors, and the price of winning is company. The month averages 22 °C, brings seven rainy days against ten in September and opens a sea that is already in swimming season, but it also holds Sant Joan and two large music festivals. The rest of this page reads the year month by month, so you can see what the choice rests on.
Month by month
Through the year
The mean temperature climbs from 8.1 °C in January to 25.4 °C in August, then slides back to 10.1 °C in December. Rain keeps a different calendar: four wet days in January and February, seven to nine through the spring, five or six in July and August, and then ten in September and nine in October.
Read together, the two curves explain the shortlist. September matches June for warmth, at 21.7 °C against 22 °C, and loses on rain, with ten wet days against seven. The table above is set to June for exactly that reason, and the rest of the page tests the choice.
Check the same room on both sites: price and cancellation terms can differ.
Seasons and what they change
The average is the monthly mean temperature from the table above. Festival dates for 2026 are an example, not a promise for next year.
Seasons move opening hours as much as weather does. The Sagrada closes at 18:00 from November to February, at 19:00 on weekdays in March and October, and at 20:00 on weekdays from April to September, while Saturday stays at 18:00 all year. A summer weekday is therefore the longest day the basilica offers.
When it is warm enough
Swimming runs from June to October, and August is the peak at about 24 to 26 °C. The lifeguards keep a similar calendar, from the end of May to mid-September, which makes late May the soft opening of the beach year. Plan the first swim for June rather than May.
Dates that change the plan
Sant Joan, on the night of 23 June, rearranges any June trip, because the city sets off fireworks that night. Primavera Sound and Sónar also fall in June, so the month holds three dated events to plan around. In 2026 they ran on 3–7 and 18–20 June, but festival dates are an example for one year and no promise for the next.
La Mercè falls around 24 September, and the week around it belongs to the festival. In mid-August the Festa Major de Gràcia does the same for that neighbourhood.
June or September
Pick June if the sea and dry days matter. It brings 22 °C, seven rainy days and swimming already in season, and it costs you the crowds that Sant Joan and the festivals bring. Unless a festival is the reason for coming, June is the safer bet.
Pick September for a sea that is still in season and a calendar with La Mercè, and accept ten rainy days, the most of any month in the year. October runs close behind with nine, and the winter hours at MNAC start on 1 October.
- June: a mean of 22 °C, seven rainy days, the swimming season open and Sant Joan on 23 June.
- August: a mean of 25.4 °C, six rainy days, the sea at its warmest and the Festa Major de Gràcia in mid-month.
- September: a mean of 21.7 °C, ten rainy days and La Mercè around 24 September.
- January: a mean of 8.1 °C, four rainy days and a Sagrada that closes at 18:00.

Before you go
Short answers to what people ask most before setting out.
What is open in winter, and what closes?
From November to February the basilica shuts at 18:00, and on Sundays it opens at 10:30. On 25 and 26 December and on 1 and 6 January it works 9:00 to 14:00. MNAC keeps its winter schedule from 1 October to 30 April, Tuesday to Saturday 10:00 to 18:00 and Sunday 10:00 to 15:00, and the Miró is open Tuesday to Sunday 10:00 to 19:00 from November to March. Picasso, MNAC and Miró are all closed on Mondays.
Can you swim in Barcelona in May?
The swimming season the sources give runs from June to October, so May sits before it. The lifeguards start only at the end of May, and the air averages 17.5 °C that month. Anyone building a beach trip around the water should start from June.
Is August too hot for sightseeing?
August has the highest mean of the year, 25.4 °C, just ahead of July with 25.1 °C. It also brings the warmest sea and six rainy days. The practical answer is the Sagrada's weekday hours, since it stays open to 20:00 from April to September, and a late slot keeps the middle of the day free for the beach.
