About Laguna de Duero
Laguna de Duero is a municipality in the province of Valladolid, in Castile and León, located at around 708 metres above sea level. With over 21,700 inhabitants, it is part of the Valladolid metropolitan area and extends along the southern bank of the Duero River. Its position on the Castilian plateau gives it a wide, clear horizon, especially towards the west, which is particularly relevant for observing the upcoming solar eclipse.
For this eclipse
On 12 August 2026, Laguna de Duero will lie within the path of totality. The eclipse will reach its maximum at 20:30 local time, with the Sun just 8.5° above the horizon and an azimuth of 282°, almost due west-northwest. The clearance above the topographic horizon is 8°, so totality should be visible provided the terrain profile and buildings to the west do not obstruct the view.
The weather in August
August in Laguna de Duero is the sunniest month of the year, with nearly 338 hours of sunshine according to AEMET records for 1991–2020. Average temperature hovers around 22.5 °C, with highs reaching 30.4 °C and lows that cool nights down to 14.5 °C. The probability of clear skies reaches 81 %, although there is a moderate risk of afternoon thunderstorms, common on the Castilian plateau at this time of year. Average monthly rainfall is scarce, barely 12.2 mm.
Past eclipses
The last notable eclipse visible from this area was the annular eclipse of 3 October 2005, now 21 years ago, with an obscuration of 90.2 % of the solar disk and an annular phase of just under three minutes. After the eclipses of 2026, 2027 and 2028, you will have to wait until 27 February 2082 for the next annular eclipse to be visible from Laguna de Duero, with an obscuration of 84.6 %.
Direction and altitude of the Sun
At the moment of maximum eclipse, the Sun will be 8.5° above the horizon, at an azimuth of 282°, which is almost exactly west-northwest. To orient yourself without instruments, simply look towards where the sun sets in summer, slightly shifted towards the north from true west. This low position requires a completely clear horizon in that direction and demands attention to possible obstacles such as buildings or dense trees to the west of your observation point.

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.
