The Community of Madrid will be one of the best places in Spain to observe the total solar eclipse of 2026. Somosierra tops the list with 1 minute and 29 seconds of total darkness, while in Hoyo de Manzanares it will last only 19 seconds.
The next total solar eclipse that will cross Spain on August 12, 2026, will show differences of up to one minute in the duration of totality depending on the municipality from which it is observed. Data provided by astronomical records place the Sierra Norte as the privileged area, with Somosierra leading the way: there, the sun will be completely obscured for 1 minute and 29 seconds, the longest record in the entire region.
The Sierra Norte, the Great Balcony of the Eclipse
The municipalities in the northern part of Madrid will enjoy a longer totality. Following Somosierra are Prádena del Rincón and Braojos, both with 1 minute and 25 seconds, and Piñuecar-Gandullas and Berzosa del Lozoya, with 1 minute and 22 and 21 seconds respectively. In Buitrago del Lozoya, totality will last 1 minute and 19 seconds, a sufficient time to appreciate the diamond ring and the complete darkening of the sky.
“The difference in duration is due to the geographical position relative to the path of totality. The further north and closer to the centre of the band, the longer the darkness,” explain astronomical sources.
In the same mountain range, towns like Rascafría (1 minute and 6 seconds) or La Cabrera (1 minute and 11 seconds) will also offer good records, although noticeably lower than those in the more northern area. For the residents of these towns, the eclipse will be a late morning spectacle: totality will begin around 19:35 and last until 20:32, just before sunset.
From Tres Cantos to Hoyo: the Southern Metropolitan Area, the Least Favoured
As one descends towards the capital and the metropolitan crown, the duration of the eclipse decreases dramatically. In Tres Cantos, totality will last only 36 seconds, and in San Sebastián de los Reyes, 31 seconds. In Colmenar Viejo, 41 seconds of total darkness can be seen, while in Hoyo de Manzanares, the phenomenon will be reduced to just 19 seconds, the lowest record in the entire Community of Madrid.
In the eastern area, municipalities like Meco (52 seconds) or Daganzo de Arriba (44 seconds) fall short. Residents of the capital, which does not appear on the list of municipalities with totality, will need to travel north if they want to see the sun completely obscured. From the city of Madrid, the eclipse will be partial, with 95% coverage, but not reaching totality.
“To see totality, one must be within the band that crosses the peninsula from west to east. Madrid city is just outside,” warn the organisers of the observations.
How to Prepare for the Great Astronomical Event
The total solar eclipse of 2026 will be the first visible in Spain since 1905, and the next will not arrive until 2028. Therefore, local administrations are already preparing observation points in the mountains. Interested parties are advised to bring certified solar filter glasses (never regular sunglasses) and, if using a telescope or binoculars, to place the appropriate filter on the lens. It is also important to check the weather forecast: a clear sky is key to enjoying the event.
In the Sierra Norte, several municipalities have announced they will install screens and public telescopes in squares and viewpoints. Somosierra, for example, plans to set up a parking area and a refreshment point for visitors coming from the capital. The partial eclipse will begin around 18:30, and totality will start between 19:35 and 19:36 depending on the municipality.
For those who cannot travel, live streaming on the internet will be an alternative, though nothing compares to the experience of seeing the solar corona with the naked eye (with protection) during those seconds of night in the middle of August. The residents of the Community of Madrid have an unmissable date with the sky: on August 12, 2026, starting at 19:30, darkness will take over the north of the region.
