About Basauri
Basauri is a Biscayan municipality nestled in Greater Bilbao, within the autonomous community of the Basque Country. With just over 42,000 inhabitants and an altitude of 57 metres above sea level, it sits at the foot of the Nervión valley, bordering the capital of Bilbao. Its urban layout and dense network of neighbourhoods make it one of Bizkaia's most populous cities, with an economy historically tied to industry and more recently to services.
For this eclipse
On 12 August 2026, Basauri lies within the path of totality of the solar eclipse. Maximum eclipse will occur at 20:27 local time, when the Sun reaches contact C3 at an altitude of 8.2 degrees above the horizon and a clearance of 6.8 degrees above the topographic profile. The Sun will be low in the sky, so it is advisable to find an elevated vantage point with a clear horizon towards the west-northwest to catch the final moments of totality.
The weather in August
August in Basauri is mild compared to the rest of the peninsula: temperatures range from an average low of 16.1 °C to a high of 26.3 °C, with a mean of 21.2 °C. The month sees around 183 hours of sunshine, though the probability of clear skies is about 44 %. With 52.7 mm of average precipitation and a moderate risk of thunderstorms, cloud cover is the main variable to monitor in the hours before the eclipse. Data: AEMET (1991–2020).
Past eclipses
The last total eclipse visible from Basauri occurred on 18 July 1860, 166 years ago, with a totality phase lasting just over two and a half minutes. Before that, on 1 April 1764, the city witnessed an annular eclipse with an obscuration of 86.9 %. After the eclipses of 2026, 2027 and 2028, one must wait until 27 February 2082 to see an annular eclipse, and until 17 November 2180 for the next total eclipse.
Direction and altitude of the Sun
At maximum eclipse, the Sun will be positioned at 8.2 degrees altitude above the horizon in a direction of 283 degrees azimuth, equivalent to west-northwest. To observe totality from Basauri, it is recommended to face towards that quadrant and ensure a clear horizon free from obstacles such as buildings or hills, given that the clearance above the topographic profile is 6.8 degrees.

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 Basauri?
The Sun was toward the WNW (azimuth 283°), 8° above the horizon at maximum from Basauri.
How long did totality last in Basauri?
Totality lasted 0 min 19 s in Basauri (C2 to C3). (corrected for the Moon's limb profile)
Was Basauri a good place to watch the eclipse?

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.
