Best time to visit Barcelona
Aim for May to August and March if you get the choice: the dry season is running but the afternoons are still bearable, and highs average 73°F (23°C) against roughly 6 wet days a month. For the same question asked the other way round, see where else is warm in May.
Pack for Barcelona with light clothing for the warm months, a warm jacket and layers for the cooler season, rain gear if you travel around October and moisture-wicking fabrics for the humidity. Even in July, lows of 71°F (21°C) make an extra layer worth the space.
