About Móstoles
Móstoles is a town in the Community of Madrid with over 207,000 inhabitants. Located at 667 metres elevation in southwestern Madrid, this city is part of the Madrid metropolitan area and has undergone notable urban growth in recent decades. Its proximity to the capital makes it an accessible reference point for observing the partial eclipse of August 2026.
For this eclipse
In Móstoles, the partial eclipse on 12 August 2026 will reach its maximum at 20:32 local time. The Sun will be 7.4 degrees above the horizon, in the west-northwest direction. Although this elevation is slightly higher than in nearby cities, it remains necessary to have a clear horizon in that direction for proper observation of the solar event.
The weather in August
August in Móstoles shows climatic features typical of the Central Plateau. The average temperature sits around 25.7 degrees Celsius, with highs near 32.8 degrees and lows around 18.6 degrees. The probability of clear skies is high, near 83 per cent, giving favourable conditions for eclipse observation, although there is a moderate risk of storms.
Past eclipses
Móstoles experienced a total eclipse 184 years ago, on 8 July 1842, when the Moon's disc completely covered the Sun over this area. More recently, an annular eclipse was visible just 21 years ago, on 3 October 2005. Following the partial eclipse of 2026, the next chance to see an annular eclipse from this territory will be on 8 December 2113.
Direction and altitude of the Sun
The Sun will follow a direction towards the west-northwest during the eclipse maximum, positioning itself at azimuth 283 degrees. At 7.4 degrees above the horizon, the visibility angle is favourable but still requires a clear line of sight in that cardinal direction for unobstructed observation.

The eclipse from Móstoles
In Móstoles, the eclipse reached its maximum at 20:33 local time, with 99.8% of the Sun covered by the Moon.
In Móstoles, the Sun was 7° above the horizon, toward the WNW. With that much margin above the horizon, any spot with open sky worked.

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.
