The Sun, Moon, and Earth align on August 12, 2026, to produce a total solar eclipse. When this celestial event last occurred, on April 8, 2024, the path of totality stretched across North America, giving millions the chance to glimpse the Sun’s corona. In 2026, the viewing locales are more limited; only a handful of land areas in the Northern Hemisphere, including parts of Iceland and Spain, fall within the path of totality.

On August 12, the Moon’s shadow will first cross over the Arctic Circle from northern Russia and then track along the eastern side of Greenland. At about 5:45 p.m. local time in Iceland (17:45 Universal Time), the country’s western fringes—including the Snæfellsnes peninsula, shown in the Landsat image above—will begin to experience totality. The greatest eclipse will occur near this sparsely populated peninsula when the Moon appears the largest and covers more of the Sun.

The Snæfellsjökull volcano on the western end of the peninsula is covered in ice and last erupted about 1,800 years ago. It is the highlight of a national park of the same name, where people are expected to visit to view the eclipse. The stratovolcano even has a literary claim to fame: in Jules Verne’s A Journey to the Center of the Earth, characters venture underground through its crater, later emerging in an eruption of Stromboli, in Italy. In 2025, a broader area of the peninsula was designated a UNESCO biosphere reserve, containing over 70 percent of Iceland’s flora and an agglomeration of volcanic landscapes, wetlands, and grasslands.

From Iceland, the eclipse shadow, or umbra, progresses across the North Atlantic and reaches northern Spain shortly before sunset. It runs east-southeast across the country, much like the Ebro River (Río Ebro), seen in the Landsat image below.

The upper Ebro emerges from rugged terrain in Parque Natural de Montes Obarenes-San Zadornil, where it carves canyons and gorges through the eastern foothills of the Cantabrian Mountains. It then meanders through La Rioja, a region known for its vineyards. About 400 kilometers (250 miles) away, the river reaches a delta on the Mediterranean coast between Barcelona and Valencia.

Based on satellite measurements of cloud cover in August over several decades, viewers in Spain have a higher likelihood than those in Iceland of getting a clear look at the eclipse. And despite limited viewing opportunities in the path of totality, the rest of Europe, parts of Africa, Canada, and the northern and northeastern U.S. will experience a partial eclipse.
