About Erandio
Erandio is a municipality in Bizkaia located on the left bank of the Nervión estuary, practically integrated into the Bilbao metropolitan area. With just over 24,000 inhabitants and an altitude of only nine meters above sea level, the locality occupies a flat, coastal territory in the heart of the Basque Country. Its riverside position connects it closely to the industrial and port dynamics of the estuary, although in recent decades it has undergone a profound urban transformation.
For this eclipse
On August 12, 2026, Erandio will lie within the path of totality of the solar eclipse. Maximum occurs at 20:27 local time, when the Sun is just 8.3° above the horizon in the west-northwest direction, with an azimuth of 283°. The margin relative to the topographic horizon is 7.4°, sufficient for the total phase to be visible, though it is advisable to find a spot without obstacles toward the west to ensure a clear view.
The weather in August
August in Erandio is the warmest month of the year, with average temperatures around 21 °C, highs around 26 °C, and lows rarely dropping below 16 °C. The probability of clear skies stands near 44%, and the municipality accumulates around 183 hours of sunshine during the month. Average precipitation exceeds 52 mm, reflecting the oceanic climate typical of the Basque coast, and there is a moderate risk of summer thunderstorms to keep in mind when planning eclipse observation. Data: AEMET (1991–2020).
Past eclipses
The last total eclipse visible from Erandio took place on July 18, 1860, 166 years ago. Before that event, the skies over the estuary had witnessed an annular eclipse on April 1, 1764. After the eclipses of 2026 and 2028, one must wait until February 27, 2082 to see the next annular eclipse, and until November 17, 2180 for the following total.
Direction and altitude of the Sun
At maximum solar coverage, the Sun will be 8.3° high above the horizon and pointing west-northwest, with an azimuth of 283°. This low but clear position means the eclipse will occur almost at sunset, casting a very characteristic twilight light over the Nervión estuary. To observe it without interruptions, it is advisable to face northwest toward the horizon and make sure there are no buildings or trees 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.

Do I need special glasses to watch the eclipse?
