Las Rozas de Madrid is a municipality in the Community of Madrid situated at the foot of the sierra, northwest of the capital. With around 95,500 inhabitants and an altitude of 718 meters, it occupies an elevated position above the Madrid plateau that affords sweeping views toward the west. The municipal territory combines consolidated residential areas with natural corridors linked to the Guadarrama River.
On August 12, 2026, Las Rozas de Madrid will experience a partial solar eclipse with maximum at 20:31. At that moment, the Sun will stand 7.5 degrees above the horizon, with a clearance of 7 degrees from the terrain profile, ensuring unobstructed visibility. Although totality does not reach this location, the percentage of solar disk covered will be perceptible to the naked eye with proper filtering.
August in Las Rozas de Madrid is characterized by low thunderstorm risk according to historical AEMET records. The continental summers of the Madrid sierra typically offer stable afternoons, without the frequency of electrical storms affecting other zones of the interior peninsula. This condition favors evening astronomical observations, since the instability associated with cumulus storms is uncommon during the eclipse hours.
The last total eclipse visible from Las Rozas de Madrid occurred on July 8, 1842, 184 years ago, with a totality duration of approximately 1 minute and 39 seconds. More recently, on October 3, 2005, an annular eclipse covered 90.2% of the solar disk for just over four minutes. The next annular eclipse visible from the area will not arrive until December 8, 2113.
At maximum on August 12, 2026 at 20:31, the Sun will stand 7.5 degrees in altitude and at an azimuth of 283 degrees, pointing nearly west-northwest. A clear horizon in that direction—for example toward the sierra or toward the plains of the Henares corridor—will allow you to follow the phenomenon uninterrupted during the final minutes of daylight.

A solar eclipse is described by four key moments, the contact points between the discs of the Sun and the Moon:
Where the eclipse is only partial, the Moon never fully covers the Sun: only C1 and C4 occur, with no totality in between.
