About Arrasate / Mondragón
Arrasate / Mondragón sits in the Deba valley within the Basque Country, at 211 meters altitude. With nearly 22,000 inhabitants and founded in 1260, it is a city marked by a strong industrial and cooperative character, recognized worldwide for the cooperative movement that emerged in its streets during the twentieth century. Its medieval historic center coexists with working-class neighborhoods that reflect decades of economic and industrial transformation in the interior Basque region.
For this eclipse
On August 12, 2026, at 20:27 local time, Arrasate / Mondragón will lie within the path of totality of the solar eclipse. At that moment, the Sun will be just 7.8° above the geometric horizon with an azimuth of 283°, but the margin relative to the topographic horizon is 4.2°, confirming that totality will be visible. The Sun's position will be very low on the horizon, making it essential to choose an observation point with a completely clear western-northwestern horizon.
The weather in August
AEMET records for August in this area (1991–2020 period) indicate a low risk of thunderstorms during the month. In the interior of the Basque Country, August is usually relatively stable, although Atlantic clouds can appear at any time. For August 12, it is advisable to check the forecast in advance and choose an observation point with a clear western horizon.
Past eclipses
The last total eclipse visible from Arrasate / Mondragón occurred on July 18, 1860, 166 years ago, with a totality phase lasting approximately two minutes and twenty-six seconds. After the three eclipses of 2026, 2027, and 2028, one must wait until February 27, 2082 for the next annular eclipse visible from this area, and until November 17, 2180 for the next total eclipse.
Direction and altitude of the Sun
At maximum, the Sun will be in the west-northwest direction, with an azimuth of 283° and an elevation of 7.8° above the geometric horizon. It is a position very close to the horizon: any obstacle in that sector—a building, a hill, or a wooded area—could compromise the view of totality. To observe the eclipse, you must face west-northwest and choose a location with the sector between west and northwest completely clear.

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.
