About Sant Boi de Llobregat
Sant Boi de Llobregat is a municipality in the province of Barcelona, in Catalonia, located 45 meters above sea level on the flat Llobregat River delta plain, very close to the Mediterranean coast. It has just over 82,000 inhabitants and is part of Barcelona's metropolitan area. Its position on flat terrain, beside the river that gives it its name, directly shapes the horizon lines from which the eclipse will be observed.
For this eclipse
On August 12, 2026, Sant Boi de Llobregat will witness a partial solar eclipse. Maximum obscuration will occur at 20:29, with the Sun at just 4° above the horizon and an azimuth of 286°. The margin relative to the topographic horizon is barely 0.9°, making this observation marginal: any obstacle to the west-northwest — buildings, trees, or hills — can block the Sun's view at that moment.
The weather in August
August in Sant Boi de Llobregat brings average temperatures of 25 °C, with highs around 29 °C and lows of 21 °C. The municipality records a 66% probability of clear skies and about 273 hours of sunshine during the month. August's average precipitation reaches 51 mm, with a moderate storm risk: although most days are sunny, summer afternoons can bring occasional downpours worth keeping in mind when planning the observation. Data: AEMET (1991-2020).
Past eclipses
The last total eclipse visible from Sant Boi de Llobregat occurred on May 12, 1706, 320 years ago, lasting nearly four minutes. The last annular eclipse was recorded on November 11, 1901, 125 years ago, with 82.2% solar obscuration and a visible ring lasting just over five minutes. After the 2026-2028 eclipses, the next annular eclipse will occur on July 13, 2075.
Direction and altitude of the Sun
At the moment of maximum eclipse on August 12, 2026 at 20:29, the Sun will be at 4° above the horizon in a direction of 286°, equivalent to west-northwest. At such a grazing height, the Sun will have already traveled much of its diurnal arc and will be in full descent toward sunset. To observe it safely, you should have a completely clear horizon line in that direction.

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.
