August is the month we would avoid in Barcelona if you have flexible dates. Expect daytime highs around 29°C, nights near 20°C and roughly 4 rainy days across the month. The hottest, most humid, and most crowded month at 29C, and the one to avoid: many family-run shops and restaurants shut for the holidays and locals leave for the coast. If August is unavoidable, book air conditioning, front-load sightseeing to early morning, and note the Festa Major de Gracia in mid-August, when Gracia's streets compete over elaborate decorations.

With highs around 29°C, August is outdoor weather: prioritize viewpoints, parks and long walks.
Sagrada Familia
TipBuy a timed ticket online days to weeks ahead, it sells out and there is no useful walk-up option in season. Book the first slot after opening for the emptiest interior and the best morning light through the eastern Nativity-facade windows, which glow blue and green early. The tower climb is a separate paid add-on with its own timed slot, so add it when you book, not on the day.
Park Guell
TipThe Monumental Zone with the mosaic terrace and the famous lizard needs a timed ticket that sells out days ahead, so book online and never walk up. Take the first slot of the day, around 9:30, to beat both the crowds and the heat on the exposed terrace, and use the Baixada de la Gloria outdoor escalators to save the steep uphill walk. The surrounding forested park is free if you only want the views without the mosaics.
Casa Batllo
TipGaudi's dragon-scaled house on Passeig de Gracia sells timed tickets that go fast in high season, so book online ahead rather than queue. Go at opening or in the last slot before close to dodge the tour-group crush on the narrow staircase, and use the included audio-augmented tablet for the animated details. Pair it with La Pedrera a five-minute walk up the same boulevard.
La Pedrera (Casa Mila)
TipGaudi's wave-fronted apartment block is another timed-ticket sight, so book online rather than turn up. The rooftop with its warrior-helmet chimneys is the payoff, best in the last daytime slot for softer light, and in summer the separate evening 'Nights of Gaudi' rooftop session with music and drinks is worth the upgrade. It sits five minutes up Passeig de Gracia from Casa Batllo, so do the two together.
