Ciempozuelos is a municipality in the province of Madrid located at the southern edge of the Madrid region, on the banks of the Jarama River. With just over 22,000 inhabitants and an altitude of 585 metres above sea level, it occupies a position on the right margin of the valley that provides expansive views towards the west and north. The town is about 35 kilometres south of the capital, nestled in the natural region of Las Vegas del Tajo.
On 12 August 2026, Ciempozuelos will experience a partial solar eclipse reaching its maximum at 20:32 local time. At that moment, the Sun will cover a significant fraction of its visible disc as it moves across the west-northwest horizon. Standing only 7.1 degrees above the topographic horizon with a clearance of 6.6 degrees, the phenomenon will be perfectly visible as long as there are no obstacles—buildings, tree groves or reliefs—in that westerly direction.
August is the warmest month of the year in Ciempozuelos. According to data from the AEMET reference station for the period 1991–2020, the average temperature hovers around 25.6 °C, with highs frequently exceeding 34 °C and night lows around 17 °C. Rainfall is very scarce—barely 6 mm average monthly—and the risk of thunderstorms is low, which favours the likelihood of clear skies on eclipse day.
The last total eclipse visible from Ciempozuelos occurred on 8 July 1842, now 184 years ago; it lasted just two minutes and seven seconds in the totality phase. More recently, on 3 October 2005, an annular eclipse covered 90.3% of the solar disc, with a central phase lasting almost four minutes. After the eclipses of 2026, 2027 and 2028, one will have to wait until 8 December 2113 for an annular eclipse to cross this latitude again.
At the moment of maximum eclipse, the Sun will be 7.1 degrees above the horizon at an azimuth of 283 degrees, that is, practically towards the west-northwest. At that hour—20:32—the Sun will already have begun its descent towards sunset, so observation requires a clear horizon in that direction. An open field or a street facing west will offer the best conditions to follow the eclipse's development until sunset.

A solar eclipse is described by four key moments, the contact points between the discs of the Sun and the Moon:
Where the eclipse is only partial, the Moon never fully covers the Sun: only C1 and C4 occur, with no totality in between.

Solar eclipses computed from astronomical ephemerides for the city's coordinates.
Yes, partial eclipse: the Sun will be 99.8% covered at maximum from Ciempozuelos.
Maximum occurs at 20:32 local time (18:32 UTC) in Ciempozuelos.
Look WNW (azimuth 283°); the Sun will be 7° above the horizon at maximum from Ciempozuelos.
Yes, Ciempozuelos is an excellent choice (score 75/100): favorable geometry, clear horizon, and good August climatology.
Yes, you need ISO 12312-2 certified eclipse glasses during every partial phase. Regular sunglasses do NOT protect. Glasses can only be removed during the totality phase (when the Sun is fully covered); never during annular or partial eclipses. Pages flagged "visible" assume a clear horizon, not a viewing recommendation.
For the August 12 eclipse. Recommended stay: Aug 10–14, 2026.
