Barcelona is set for unstable weather on Tuesday, 12 May 2026, with afternoon showers and thunderstorms predicted for the prelittoral region and a possibility of affecting the city itself. This follows a calm and warm Monday, according to Betevé.
The morning will start clear and cool, with temperatures requiring a light jacket or jumper at 6am. By 9am, skies will be clear, but clouds are expected to build by midday. The afternoon will bring uncertain weather, with umbrellas advised from 3pm.
Afternoon Storms Forecast
There is a chance of showers or storms in Barcelona by 6pm, with skies clearing by 9pm and a cool evening by 11pm. The storms are expected to be more significant in the prelittoral, moving from west to east and potentially bringing heavy rain and hail in some areas, particularly along the Maresme coast.
Catalonia's meteorological service, Meteocat, has issued precipitation intensity warnings. These alerts are due to the possibility of more than 20 litres of rain falling within 30 minutes in affected areas.
Unsettled Week Ahead
The unsettled afternoon weather is set to continue over the coming days, with showers mainly concentrated near Montseny. By Thursday, the showers could become more widespread, potentially reaching Barcelona. Overall, cooler temperatures are expected across the region for the rest of the week.
