The Moon’s shadow swept across Spain on August 12, with the path of totality, where the Moon completely obscured the Sun, stretching across approximately 40% of Spanish territory. Totality was brief at any fixed location: NASA eclipse calculations put the maximum basic duration at about 2 minutes 18.2 seconds, while the full progression from first to last contact lasted close to two hours. It was the most extensive such event in recent decades.
Information from the interactive map published by EL PAÍS, the eclipse was visible to varying degrees across the country. Regions inside the narrow path of totality saw the Sun fully covered, while most locations experienced a partial eclipse. The duration and degree of solar coverage varied by municipality, and the map marked the central line, where totality lasted longest. Reports put local totality at around 20:28 in León; Zaragoza followed at 20:29, with Valencia at 20:32.
The shadow’s trajectory crossed 13 of Spain’s 17 autonomous communities and affected at least 31 of its 50 provinces. The totality track extended far beyond Spain, crossing Arctic regions before moving through northern Russia. It passed near Greenland and Iceland, crossed the North Atlantic and entered the northern Iberian Peninsula before ending over the western Mediterranean. Partial phases were visible across much of Europe, as well as parts of Canada, Alaska, the northeastern United States and northwestern Africa.
At the point of greatest eclipse, recorded at 17:45:53.8 UT, the Sun’s azimuth was approximately 248.4 degrees, and the lunar shadow was moving across Earth at roughly 3,700 km/h. The basic maximum duration did not apply at every viewing location; Spanish observers within the path saw shorter periods of totality. The shadow’s speed also meant local timings along the Spanish route differed by only a few minutes.
Authorities urged people in the totality zone to choose observation points close to home, limiting unnecessary travel, congestion and other logistical pressure. Local councils and regional governments prepared designated viewpoints for larger gatherings. The EL PAÍS map also included a shadow overlay showing whether local terrain would block the Sun at the eclipse’s peak.
In Madrid, crowd-management and fire-safety concerns led to the cancellation of several public viewing events. A recent report said 30 of 52 municipalities maintained their eclipse plans despite wildfire risks. Rivas-Vaciamadrid’s municipal fire-prevention service reported special surveillance at the city’s Mirador on August 12, where hundreds gathered to watch. The operation was part of wider summer prevention work: the service recorded more than 200 interventions, including 10 wildfire starts and three fires that required firefighters. Further details are in this coverage of Madrid's eclipse event cancellations.
Other municipalities also adjusted operations for the expected crowds. In Alicante, beach lifeguard coverage was extended until 22:00 on August 12, with 58 lifeguards involved. A special security operation covered the city’s castles, and also Serra Grossa and Tabarca. The Instituto de Astrofísica de Canarias deployed equipment across the peninsula and announced a live broadcast from Palencia, adding an institutional observing and public-outreach effort to local preparations.
Solar eclipses are rare in Spain; the last total eclipse visible from the mainland occurred in 2005. The event drew particular interest in regions along the path of totality. Experts recommend certified eclipse glasses or indirect viewing methods to protect eyesight, since looking directly at the Sun can cause permanent damage. Spain is not expected to see a similar event for several decades, making this a rare occasion for residents and visitors.
