About Mieres
Mieres is a municipality in Asturias, located inland in the Caudal River valley, at an elevation of 367 meters and approximately 20 kilometers south of Oviedo. With a population of around 44,000, it was known in the 20th century as one of Spain's leading coal mining centers. Today, its industrial heritage and mountain landscape coexist, shaping the town's unique character and scenery.
For this eclipse
On August 12, 2026, Mieres will lie within the path of totality. At maximum eclipse, occurring at 20:27 local time, the Sun will be 10 degrees above the horizon, with a clearance of 7.7 degrees above the terrain horizon—totality is expected to be unobstructed. Based on geometric conditions, the observation of totality from the city looks promising.
The weather in August
August in Mieres records an average precipitation of 53.4 millimeters according to AEMET data (1991–2020), making it one of Spain's rainiest regions even at the height of summer. The thunderstorm risk in this month is high, a characteristic of Asturias' Atlantic climate. When planning to observe the eclipse, careful attention to the weather forecast up to the day before is essential.
Past eclipses
The last total solar eclipse visible from Mieres occurred on August 30, 1905—121 years ago. Totality lasted 3 minutes 49 seconds. Before that, on April 1, 1764, an annular eclipse occurred with 86.9% obscuration. After the eclipses of 2026, 2027, and 2028, the next annular eclipse won't occur until February 27, 2082, and the next total eclipse until November 17, 2180.
Direction and altitude of the Sun
At maximum eclipse, 20:27 local time, the Sun will be at an azimuth of 281 degrees—nearly west-northwest—10 degrees above the horizon. At this evening hour, sunlight strikes from a low angle; during totality, a distinctive twilight hue will envelop the surroundings. Looking west-northwest will allow you to easily observe this phenomenon.

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?
