Barcelona weather by month
Source: Meteorological data for Barcelona is based on weather statistics gathered for the period 1991 to 2020 by Agencia Estatal de Meteorología (AEMET) – Spain's meteorological agency – from the closest weather station: Josep Tarradellas Barcelona–El Prat Airport (BCN), or Barcelona-El Prat Airport, located 15km (9mi) southwest of the centre of Barcelona.
Advice on the best time to visit a particular destination is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
