When can you see the Perseids in Spain in 2025? The best day and where to best view the largest meteor shower of the summer.

Every summer , the night sky becomes a magical setting where meteor showers deliver fleeting flashes that captivate observers around the world. These showers, also popularly known as "shooting stars," are actually tiny particles that, upon entering Earth's atmosphere at high speed, burn up and produce the characteristic luminous streaks we can see with the naked eye. Among the most anticipated meteor showers of 2025 are the Perseids, an event that offers unique opportunities to connect with the cosmos.

The most anticipated event of the summer, also known as the "tears of Saint Lawrence" due to its coincidence with the martyr's feast day, celebrated on August 10. In 2025, this shower will last until August 24, peaking on the night of August 12-13.

During that peak, the meteor shower rate is expected to reach up to 100 per hour under optimal conditions, although the presence of the full Moon on August 9 may make observing the fainter meteors difficult. Therefore, the best viewing window will be the early morning of August 13, especially between 2:00 and 5:00 a.m. , when the Perseus radiant is highest in the sky and darkness is at its greatest.

To fully enjoy the spectacle, it's essential to find locations away from light pollution and with clear skies. In Spain, some of the top-rated sites for astronomical quality are:

- Montsec (Lleida): a natural observatory with Starlight certification, which guarantees dark skies and good visibility.

- Cíes Islands (Galicia): known for their protected environment and minimal light impact.

- Monfragüe National Park (Cáceres) : a natural refuge with landscapes ideal for observation.

- Sierra de Gredos (Ávila) : high mountains and low pollution that favor the nightlife experience.

-La Palma Island (Canary Islands) : one of the best skies in the world for professional and amateur astronomy.

-Sierra Nevada (Granada) and Sierra Norte de Madrid : for those looking to escape the city without going too far.

-Albanyà (Girona): with clear and calm skies, perfect for starry nights.

Look for a clear horizon and avoid obstacles such as trees or buildings that obscure your view. Move your gaze away from the Moon, if it's visible, to reduce the impact of its light. Also, wear comfortable clothing and something to lie on, such as a blanket or a reclining chair, to avoid fatigue during the wait.

Patience and time: It can take up to 20 minutes for your eyes to adapt to the dark, so avoid looking at artificial light sources. And check the weather forecast to choose clear nights with low humidity.

So, if you want to experience an unforgettable night this summer of 2025, mark your calendars for the aforementioned dates, prepare your basic equipment—and a suitable location—and let yourself be amazed by the "Tears of San Lorenzo" and their stellar companions.
