About Amposta
Amposta is a municipality in Tarragona province, in southern Catalonia, situated on the banks of the Ebro River just a few kilometres from its mouth at the Mediterranean Sea. With just over 21,000 inhabitants, it sits at barely 11 metres above sea level in the Montsià region. The immediate surroundings are marked by rice fields, lagoons and open landscapes of the Ebro Delta, within the homonymous natural park.
For this eclipse
On 12 August 2026, Amposta will lie in the path of totality of the solar eclipse. The phenomenon reaches its maximum at 20:30 local time, when the Sun will be just 4.5 degrees above the horizon. With a margin of two degrees from the topographic horizon, totality will be visible, but the Sun's low position demands caution: any obstacle—tree, building, hill—can block the view. It is advisable to position yourself at a location with a completely clear western horizon.
The weather in August
August in Amposta is the sunniest month of the year, with about 291 hours of sunshine monthly and a probability of clear skies close to 70%. Average temperatures hover around 27 °C, with highs that can exceed 33 °C and lows around 21 °C. Average monthly rainfall does not reach 28 millimetres, but the risk of thunderstorms is high, with convective instability episodes that can cloud the sky rapidly. Data: AEMET 1991–2020.
Past eclipses
The last total solar eclipse visible from Amposta took place on 30 August 1905, 121 years ago, with a totality of 188 seconds. Before that, an annular eclipse was recorded on 11 November 1901 in the area. After the eclipses of 2026, 2027 and 2028, one must wait until 13 July 2075 for an annular eclipse to cross the area again; the next total will not arrive until 17 November 2180.
Direction and altitude of the Sun
At the moment of totality, the Sun will be at an azimuth of 286 degrees, that is, facing almost due west with a slight inclination towards the northwest—the direction known as west-northwest (WNW). The height above the horizon will be 4.5 degrees, barely above the horizon line. To enjoy totality without obstruction, observers should seek a location with an open horizon in that direction, with no buildings or woodland in that part of the sky.

01
The eclipse from Amposta
In Amposta, totality began at 20:30 local time and lasted 1 min 31 s, until 20:32. The eclipse maximum fell at 20:31.
In Amposta, the Sun was 5° above the horizon, toward the WNW. Even so, a clear horizon toward the WNW helped.
This area typically sees around 10% median cloud cover at that hour, based on ten years of historical data — not a forecast for this specific eclipse.

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.

Which direction was the Sun in during the eclipse from Amposta?
The Sun was toward the WNW (azimuth 286°), 5° above the horizon at maximum from Amposta.
How long did totality last in Amposta?
Totality lasted 1 min 31 s in Amposta (C2 to C3). (corrected for the Moon's limb profile)
Was Amposta a good place to watch the eclipse?
Amposta saw totality (C2-C3) very close to the western horizon. The partial end (C4) fell below the horizon: a clear western view was needed for an epic experience.
Do I need special glasses to watch the eclipse?
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.
