About Calahorra
Calahorra nestles in the Ebro valley, near the confluence of the Cidacos and Ebro rivers, in the southeastern tip of La Rioja. With nearly 25,000 inhabitants and an altitude of 352 metres above sea level, it is the second most populated city in this autonomous community. Its location on the Rioja plains, surrounded by vineyards and farmland, offers wide horizons in virtually every direction.
For this eclipse
On 12 August 2026, Calahorra lies within the path of totality. The eclipse reaches maximum at 20:28 local time, with the Sun at just 7 degrees above the horizon and an azimuth of 284 degrees: west-northwest direction. The margin above the topographic horizon is 6.2 degrees, making totality visible provided the horizon in that direction remains unobstructed.
The weather in August
AEMET records for the 1991–2020 period indicate that the risk of thunderstorms in August is low in this southern Rioja region. Summer afternoons in the Ebro valley tend to see atmospheric stability and clear skies, conditions that from a climatological standpoint favour eclipse observation. The low thunderstorm activity in this month is a positive factor for 12 August.
Past eclipses
The last total solar eclipse visible from Calahorra occurred on 30 August 1905, 121 years ago, with a totality phase of around 107 seconds. Shortly before, on 11 November 1901, the city also experienced an annular eclipse. After the eclipses of 2026, 2027 and 2028, the next annular will not come until 27 February 2082 and the next total until 17 November 2180.
Direction and altitude of the Sun
At the moment of totality, at 20:28 on 12 August, the Sun will be 7 degrees above the horizon to the west-northwest, with an azimuth of 284 degrees. The low position of the Sun at that afternoon hour requires choosing an observation point without buildings, trees or terrain features in that direction. An open field south of the city or a terrace with a clear view to the west-northwest will offer the best visibility conditions.

01
The eclipse from Calahorra
In Calahorra, totality began at 20:28 local time and lasted 1 min 13 s, until 20:30. The eclipse maximum fell at 20:29.
In Calahorra, the Sun was 7° above the horizon, toward the WNW. With that much margin above the horizon, any spot with open sky worked.
This area typically sees around 17% 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.

Frequently asked questions about the eclipse in Calahorra
Was the eclipse of August 12, 2026 visible from Calahorra?
Yes — Calahorra was inside the totality path and the horizon allowed the total phase to be fully visible.

Maximum occurred at 20:28 local time (18:28 UTC) in Calahorra.
Which direction was the Sun in during the eclipse from Calahorra?
The Sun was toward the WNW (azimuth 284°), 7° above the horizon at maximum from Calahorra.
How long did totality last in Calahorra?
Totality lasted 1 min 13 s in Calahorra (C2 to C3). (corrected for the Moon's limb profile)
Was Calahorra a good place to watch the eclipse?
Calahorra 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.
