About Arroyomolinos
Arroyomolinos is a municipality in the province of Madrid located in the foothills of the Guadarrama range, at 598 metres elevation. With just over 31,000 inhabitants, it forms part of the western metropolitan area of the capital. Its position in the sierra's foothills gives it a landscape of transition between mountain and Madrid's plains, with wide views towards the west and south.
For this eclipse
On 12 August 2026, Arroyomolinos will lie outside the totality corridor: the eclipse will be partial here. The maximum occurs at 20:32, when the Sun will be 7.4 degrees above the horizon, with a margin of 6.7 degrees above the local horizon profile. From any point with a clear western horizon, observation is feasible. The verdict is visible, ensuring favourable conditions to follow the phase of maximum obscuration.
The weather in August
In August, Arroyomolinos records an average temperature of 25.7 °C, with highs around 32.8 °C and lows of 18.6 °C. The probability of clear skies that month reaches 83%, backed by an average of 344 sunshine hours, making August one of the sunniest months of the year. Average rainfall is scarce — about 10.8 mm — though the risk of thunderstorms is moderate, a feature typical of mountain summers in Madrid. Data: AEMET (1991–2020).
Past eclipses
The most recent total eclipse visible from Arroyomolinos dates back to 8 July 1842, 184 years ago, with a totality phase lasting just under two minutes. More recent was the annular eclipse of 3 October 2005, which covered nearly 90% of the solar disk. After the eclipses of 2026 to 2028, the next annular eclipse visible from here will not occur until 8 December 2113.
Direction and altitude of the Sun
At the moment of eclipse maximum, at 20:32 on 12 August, the Sun will be at 283 degrees azimuth and 7.4 degrees above the horizon. That direction corresponds to west-northwest, close to sunset but slightly offset towards the north. The altitude, though low, leaves a margin of 6.7 degrees above the local horizon, so from clear points with an open western horizon observation is feasible without the need for a special location.

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.
