About Arganda
Arganda is a municipality in the Community of Madrid located in the valley of the Jarama River, about 27 kilometres southeast of the capital. It sits at 626 metres altitude on gently rolling plains and is home to approximately 51,500 inhabitants. It forms part of the Henares-Jarama industrial corridor and combines established residential zones with economic activity hubs that have driven its growth over recent decades.
For this eclipse
On 12 August 2026, Arganda will experience a partial solar eclipse with maximum at 20:32 local time. At that moment the Sun will be 7.1° above the horizon, with a clearance of 7.2° from the terrain profile, ensuring good visibility without obstructions. Although the locality lies outside the path of totality, the lunar disc will cover a significant fraction of the Sun, producing a noticeable dimming of ambient light at sunset.
The weather in August
August in Arganda falls within Madrid's continental summer: clear skies predominate and thunderstorm risk is low according to AEMET climatological records for the 1991–2020 period. Afternoons are typically dry and warm, with sparse cloud cover, which favours astronomical observations. The stable atmosphere at this time of year makes the eclipse timeframe, as the sun sets, especially conducive to seeing the phenomenon clearly.
Past eclipses
The last total eclipse visible from Arganda occurred on 8 July 1842, 184 years ago, with totality lasting just over two minutes. More recently, on 3 October 2005, an annular eclipse crossed the area with an obscuration of 90%, offering a ring of fire that many residents still remember. The next annular eclipse will not arrive until 8 December 2113.
Direction and altitude of the Sun
At the moment of maximum eclipse, the Sun will be in the west-northwest of the sky, with an azimuth of 284° and an altitude of 7.1° above the horizon. To observe it, it is best to orient yourself towards that clear quadrant, seeking a point with an unobstructed view towards the west. The low altitude indicates that the eclipse will occur during twilight, so the western horizon must remain clear of obstructions such as buildings or vegetation.

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.
