About Leioa
Leioa is a municipality in the province of Bizkaia, in the Basque Country, with just over 31,000 inhabitants and an altitude of 24 meters above sea level. Its low elevation reflects its location on the Atlantic coastal zone on the left bank of the Nervión estuary. Founded in 1526, it is now part of the Bilbao metropolitan area and has evolved from a small rural settlement to a consolidated urban municipality over the course of the twentieth century.
For this eclipse
For the eclipse of August 12, 2026, Leioa lies within the path of totality. The maximum of the total phase will occur at 20:27 local time, with the Sun at 8.3 degrees above the horizon. The margin of 7.1 degrees from the topographic horizon indicates that totality will be visible from the municipality without terrain obstruction. It is advisable to find a clear position toward the west-northwest to keep the horizon unobstructed in that direction.
The weather in August
According to AEMET's climatological data for the period 1991–2020, August in Leioa is a mild month. Average temperatures range from 16.2 °C (minimum) to 23.3 °C (maximum), with a mean of 19.8 °C. Average monthly precipitation is 44.8 mm, a notable figure for summer and typical of the Atlantic climate of the Basque coast. The risk of storms in August is high, so weather forecasts for the days leading up to the eclipse will be a key factor for observation.
Past eclipses
The last total eclipse visible from Leioa took place on July 18, 1860, 166 years ago, with a duration of totality of about 2 minutes and 41 seconds. Previously, on April 1, 1764, an annular eclipse crossed the area with an obscuration of 86.9%. After the eclipses of 2026, 2027, and 2028, the next annular eclipse visible from this latitude will not arrive until February 27, 2082, and the next total eclipse until November 17, 2180.
Direction and altitude of the Sun
At the moment of maximum eclipse, at 20:27 local time, the Sun will be 8.3 degrees above the horizon, in a direction of 283 degrees azimuth, equivalent to west-northwest. The Sun will be well into its evening descent, relatively low but still well above the horizon. From Leioa, it is important to position yourself with clear views toward the west-northwest and verify that no obstacles obstruct the first few degrees above the horizon in that direction.

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.
