About Cerdanyola del Vallès
Cerdanyola del Vallès is a municipality in the province of Barcelona, Catalonia, nestled in the foothills of Collserola park at 88 metres above sea level. With just under 59,000 inhabitants, it occupies the northern sector of Vallès Occidental, between the Ripoll river corridor and the Collserola mountain range. Its position north of the Barcelona metropolitan area gives it a semi-urban setting with access to relatively open horizons towards the west.
For this eclipse
On 12 August 2026, Cerdanyola del Vallès will experience a partial solar eclipse with maximum at 20:28, when the Sun will be just 4° above the horizon. The Sun will be positioned in the west-northwest direction, at an azimuth of 286°. With a margin of 2.8° relative to the local topographic horizon, observation will be possible, but any obstruction in that direction—buildings, trees, or terrain—could compromise visibility in the final minutes.
The weather in August
August in Cerdanyola del Vallès is characterised by distinctly summer temperatures: the 1991–2020 average places daytime temperatures around 30 °C and night-time temperatures near 18 °C, with a daily mean of 24.2 °C. The risk of thunderstorms is low, which favours the likelihood of clear skies on the afternoon of the eclipse. The data come from the nearest AEMET weather station. (Data: AEMET.)
Past eclipses
The last total eclipse visible from Cerdanyola del Vallès dates back to 12 May 1706, 320 years ago, with more than three minutes of totality. The most recent annular eclipse occurred on 11 November 1901, 125 years ago. After the eclipses of 2026 and 2028, you will have to wait until 13 July 2075 for another annular eclipse to cross this region of Catalonia.
Direction and altitude of the Sun
At the moment of maximum eclipse, the Sun will be positioned in the west-northwest direction, with an azimuth of 286° and an altitude of just 4° above the geometric horizon. This is a very low position: it is roughly equivalent to four solar diameters above the horizon line, so it is wise to choose a location with an unobstructed field of view in that direction to avoid missing 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.
