About Errenteria
Errenteria is a municipality in Gipuzkoa, in the Basque Country, stretching along the banks of the Oiartzun river just a few kilometres from Donostia-San Sebastián. With a population of around 38,700 inhabitants and an altitude of barely 9 metres above sea level, the city occupies a valley wedged between the hills that characterise the landscape of inland Gipuzkoa. Founded in 1320, it retains a urban fabric that blends its historic core with the industrial neighbourhoods developed during the twentieth century.
For this eclipse
On 12 August 2026, Errenteria will experience a partial solar eclipse reaching its maximum at 20:27 local time. At that moment the Sun will be just 7.6° above the horizon in the west-northwest direction, meaning that any elevated obstruction towards the west—hills, buildings or trees—may interfere with visibility. With a margin of just 2.8° above the topographic horizon, it is worth finding a clear spot in that direction so as not to miss the event.
The weather in August
AEMET records from station 1012P covering the period 1991-2020 show that August in Errenteria carries a low risk of thunderstorms, which is favourable for eclipse observation. The Oiartzun valley can accumulate low fog in the early hours of the day, although summer afternoons tend to be more stable. For the eclipse, which occurs in late afternoon, the statistical conditions point to a reasonable probability of partly clear skies.
Past eclipses
The last annular eclipse visible from Errenteria occurred on 1 April 1764, 262 years ago, with an obscuration of 86.9 % that covered nearly nine-tenths of the solar disc. Following the partial eclipse of 2026 and those coming in 2027 and 2028, observers will have to wait until 27 February 2082 for another annular eclipse to cross this latitude, with an obscuration of 84.5 %.
Direction and altitude of the Sun
At maximum eclipse, at 20:27, the Sun will stand 7.6° high above the horizon and at an azimuth of 283°—that is, nearly due west-northwest. At that hour the star is already descending towards sunset, so observation requires a clear horizon in that direction. The margin of 2.8° with respect to the local topographic relief is sufficient to see the eclipse as long as there are no significant artificial or natural obstacles to the west.

The eclipse from Errenteria
In Errenteria, the eclipse reached its maximum at 20:27 local time, with 99.6% of the Sun covered by the Moon.
In Errenteria, the Sun was 8° above the horizon, toward the WNW. Even so, a clear horizon toward the WNW helped.
This area typically sees around 40% 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.

Was Errenteria a good place to watch the eclipse?
Errenteria could see the eclipse with limitations (score 47/100): terrain, geometry, or climatology added risk. A higher-scored viewpoint would have been preferable.
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.
