About Aranda de Duero
Aranda de Duero is a municipality in the province of Burgos, in Castilla y León, with slightly over 33,000 inhabitants. Situated at 800 meters altitude above the Duero river basin, it occupies the heart of the region known as Ribera del Duero. Its position on the Castilian plateau gives it a marked continental climate, with warm summers and cool nights. It is known as the capital of the Ribera del Duero in Burgos province, one of Spain's most renowned wine regions.
For this eclipse
On August 12, 2026, Aranda de Duero lies within the path of totality. At 20:29 local time, the Sun reaches the maximum of the total phase at only 7.8° above the horizon. Totality will be fully visible as long as the terrain profile to the west-northwest is clear. With the Sun so close to the horizon, it is wise to verify that there are no obstacles such as hills, buildings, or trees in that direction before choosing your observation point.
The weather in August
August in Aranda de Duero features temperatures typical of the Castilian plateau: an average of 20.8 °C, with highs around 30 °C and lows that can drop to 11.5 °C at night. The risk of storms in August is low, which favors stable conditions for eclipse observation. The data correspond to the 1991–2020 period from AEMET's network of weather stations.
Past eclipses
The last total eclipse visible from Aranda de Duero occurred on August 30, 1905, 121 years ago, with a totality phase of approximately 3 minutes and 21 seconds. Before that, on April 1, 1764, an annular eclipse covered 87% of the Sun for approximately 6 minutes. After the eclipses of 2026 and 2028, the next annular eclipse visible from the city will occur on February 27, 2082.
Direction and altitude of the Sun
At the moment of maximum totality, at 20:29, the Sun will be at 7.8° above the horizon, with an azimuth of 283°: a direction almost due west, slightly offset toward the northwest. This grazing position requires choosing a location with no obstacles on the western horizon. The combination of low solar altitude and visible totality will cause the darkened sky to contrast with the last colors of dusk, adding particular visual interest to the phenomenon.

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.
