About San Sebastián de los Reyes
San Sebastián de los Reyes is a municipality in the Community of Madrid located north of the capital, in the Campiña region. With nearly 76,000 inhabitants and an elevation of 685 meters above sea level, it forms part of the Madrid metropolitan area. Founded in 1492, its position on the Castilian plateau grants it a broad western horizon, a condition relevant for astronomical observation.
For this eclipse
On 12 August 2026, San Sebastián de los Reyes lies within the path of totality: the eclipse is total and contact C3—the beginning of the third phase—occurs at 20:31 local time. At that moment the Sun will be 7.3° above the horizon, with a margin of 6.7° relative to the topographic horizon, allowing for clear viewing. The solar corona will be visible during the brief seconds of totality.
The weather in August
According to AEMET historical records for 1991–2020, August in San Sebastián de los Reyes presents a low thunderstorm risk, favorable for eclipse observation in the late afternoon. The municipality, nestled on the Castilian plateau, enjoys the dry, luminous summers characteristic of continental Mediterranean climate, with typically stable afternoons and little rainfall in this month.
Past eclipses
The last total eclipse visible from San Sebastián de los Reyes was on 8 July 1842, 184 years ago, with a totality of just under two minutes. On 3 October 2005, an annular eclipse occurred with an obscuration of 90.3% and a central duration of about four minutes. Following the eclipses of 2026, 2027, and 2028, the next significant annular eclipse will not reach this location until 8 December 2113.
Direction and altitude of the Sun
At maximum eclipse, at 20:31 on 12 August 2026, the Sun will be positioned 7.3° above the horizon, toward the west-northwest, with an azimuth of 283°. This low position in the evening sky requires a location with clear western horizon: avoiding tall buildings, dense vegetation, or terrain relief in that direction will ensure the best visibility during totality.

What the contact points (C1-C4) mean
A solar eclipse is described by four key moments, the contact points between the discs of the Sun and the Moon:
- C1First contact: the Moon touches the edge of the Sun and the partial eclipse begins.
- C2Second contact: the Moon fully covers the Sun and totality begins.
- C3Third contact: the Sun reappears and totality ends.
- C4Fourth contact: the Moon leaves the Sun's disc and the eclipse ends.
Where the eclipse is only partial, the Moon never fully covers the Sun: only C1 and C4 occur, with no totality in between.
