The eclipse will occur when the Moon passes between the Earth and the Sun, almost completely obscuring the solar disc. Weather permitting, Barcelona will have an excellent view of the phenomenon as it gradually alters the evening light and creates an unusual spectacle in the sky.

The new City Council eclipse website provides accessible information explaining what an eclipse is, how it occurs and the precautions needed to observe it safely. It also brings together details of eclipse viewing and educational activities organised by venues and organisations across the city.

Safety measures

Watching a solar eclipse is a remarkable experience, but it is important to take appropriate precautions to avoid damaging your eyesight. Never look directly at the Sun without proper protection, even during a partial eclipse, as solar radiation can cause serious and permanent eye damage.

To enjoy the eclipse safely, follow these recommendations:

• Use certified solar viewing glasses that meet the appropriate safety standards for viewing eclipses. Conventional sunglasses offer no protection.
• Never look directly at the Sun through cameras, binoculars or telescopes unless they are fitted correctly with the appropriate solar filters.
• When using optical equipment, make sure it has suitable solar filters and always follow the manufacturer’s instructions.
• If you do not have specialist equipment, use indirect viewing methods, such as projection using proper materials.
• Children should be closely supervised while viewing the eclipse.

In the unlikely event of an eye emergency, go to one of the following hospitals:

• Vall d’Hebron: 24 hours
• Hospital del Mar: weekdays, 8 am to 8.30 pm; weekends, 10 am to 8.30 pm
• Hospital Clínic: 24-hour ophthalmology emergency service
• Hospital Sant Pau: 24-hour ophthalmology emergency service

Safety, mobility and crowd management measures for the solar eclipse

The Guàrdia Urbana will deploy special measures across the city in anticipation of crowds gathering at viewpoints, beaches and other open spaces. Preventive patrols will be stepped up, alongside mobility management and coordination with the emergency services, to ensure the eclipse can be viewed safely. Access to Parc de Collserola remains restricted due to African swine fever.
