About Alcalá de Guadaira
Alcalá de Guadaira is a municipality in the province of Seville, in Andalusia, with just over 70,000 inhabitants and an altitude of 71 meters above sea level. Located southeast of the Seville capital, along the natural corridor traced by the Guadaira River before its confluence with the Guadalquivir, the city combines a consolidated urban center with a periurban countryside landscape. Its geographic position places it firmly within the Seville metropolitan area.
For this eclipse
On August 12, 2026, Alcalá de Guadaira will experience a partial solar eclipse with its maximum reaching 20:37 local time. The Sun will be 7.2° above the horizon at that moment—a moderate altitude but sufficient to observe the phenomenon without the usual obstructions. The margin relative to the topographic horizon is 7.2°, so it is advisable to find a location with a clear western horizon. It is not recommended to rely on rooftops or terraces with obstacles in that direction.

August in Alcalá de Guadaira is the warmest month of the year. According to AEMET data from the 1991–2020 period, the average temperature is around 28.6 °C, with maximum averages reaching 36.2 °C and minimum nighttime temperatures of 20.9 °C. The municipality records approximately 347 hours of sunshine in August and a probability of clear skies of 84 %.

Before that event, on April 1, 1764, an annular eclipse occurred with 86.9 % obscuration and an annular phase of 230 seconds. After the 2026–2028 eclipses, one must wait until July 13, 2075 to see an annular eclipse, and until June 20, 2327 for the next total.
Direction and altitude of the Sun
At the moment of maximum eclipse, the Sun will be 7.2° high above the horizon and at an azimuth of 283°, which corresponds to the west-northwest direction. It will be practically at the last hour before sunset, tracing a descending path toward the western horizon. To follow the eclipse without interruption, the best position is an open place facing west-northwest, with no buildings or trees in that sky band.

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.
