Spain is positioned for one of the most unusual eclipse seasons in modern astronomy this summer. Three separate solar eclipses are visible from Spanish territory between June and September 2026, culminating in a total solar eclipse on August 12 whose path of totality crosses directly over the Iberian Peninsula. For residents and visitors in the right locations, the August event will produce complete daytime darkness lasting up to two minutes and ten seconds.
Eclipse 1 | Partial Solar Eclipse, June 21, 2026
The summer sequence opens with a partial solar eclipse on June 21, 2026, visible across most of mainland Spain, the Canary Islands, and the Balearic Islands. At maximum, the moon covers roughly 40 to 55 percent of the sun's disk as seen from central Spain, with coverage increasing toward the southwest. Madrid sees peak eclipse at approximately 12:08 local time; Seville, which is farther southwest, sees slightly higher coverage closer to 12:15. The Canary Islands experience a deeper partial phase given their position farther south and west.
This eclipse requires eye protection for the entire duration. No location in Spain experiences totality on June 21. ISO-certified eclipse glasses or a solar filter on a telescope are required from first contact to last contact.
Eclipse 2 | Annular Solar Eclipse, July 23, 2026
An annular eclipse on July 23, 2026, produces the characteristic "ring of fire" effect: the moon is near apogee (its farthest point from Earth), making its apparent disk slightly smaller than the sun. For observers in the annularity path, the sun appears as a bright ring around a dark lunar disk for up to 2 minutes 17 seconds. The annularity path enters Spain from the Atlantic, crosses the Canary Islands, and continues east. From Gran Canaria and Tenerife, conditions are favorable for full annularity assuming clear skies.
Mainland Spain is outside the annularity path but experiences a deep partial eclipse, with 70 to 85 percent coverage across Andalusia and the southwestern coast. During the annular phase, even though a ring of bright sunlight remains visible, direct eye protection is still mandatory throughout the entire event.
Eclipse 3 | Total Solar Eclipse, August 12, 2026
The August 12 total solar eclipse is the centerpiece of the summer and one of the most significant astronomical events to cross Europe this decade. The path of totality enters Spain from the Atlantic, sweeps across Galicia in the northwest, passes through Asturias, Cantabria, and the Basque Country, and continues northeast into France and Switzerland. Cities inside the path include Santiago de Compostela, Oviedo, Santander, and Bilbao, all of which will experience totality.
During totality, the sky darkens to twilight conditions, the solar corona becomes visible to the naked eye, bright planets and stars appear, and temperatures can drop several degrees in minutes. The duration of totality varies by location: observers near the centerline of the path can expect up to 2 minutes 10 seconds of complete darkness. Outside the path, the rest of mainland Spain experiences a deep partial eclipse ranging from 85 to 99 percent coverage depending on proximity to the totality corridor.
The Spanish Meteorological Agency (AEMET) is expected to publish cloud cover forecasts for August eclipse viewing locations closer to the date. August in northern Spain carries moderate cloud risk, particularly in Galicia and coastal Cantabria, making flexibility in viewing location valuable for those traveling specifically for totality.
How to Watch Safely
Eye protection rated to the ISO 12312-2 international standard is required for all three eclipses except during the brief totality phase of the August 12 event, when it is safe to look without filters only while the sun is completely covered. The moment the diamond ring effect appears at the end of totality, filters must go back on immediately. No unfiltered viewing is safe during the partial or annular phases of any of the three events.
Pinhole projectors, solar telescopes, and dedicated solar binoculars are alternatives for extended observation. Smartphone cameras require solar filters on the lens for direct sun photography outside totality. The International Astronomical Union and NASA both publish updated eclipse safety guidance each year. For path maps and precise local contact times, NASA's eclipse website at eclipse.gsfc.nasa.gov provides exact figures for any coordinates.
This summer's three-eclipse sequence in Spain is rare by any historical measure. The last time a total solar eclipse crossed mainland Spain was in 1905. If you are planning travel to the Iberian Peninsula this summer, the August 12 path of totality across northern Spain is among the most accessible total eclipse opportunities in Europe for the remainder of this decade. The science of predicting these events relies on the same orbital mechanics that powers missions like the MAVEN Mars orbiter and the dynamics that underlie discoveries like the newly confirmed wind from Sagittarius A*, our galaxy's central black hole.
