On Monday, August 2, 2027, mid-morning light will vanish over Cadiz for nearly three minutes.
This will be no ordinary dimming. It will be a total eclipse—the kind that turns morning into twilight and makes the solar corona visible to the naked eye.
It is also the standout event on 2027’s astronomical calendar: the longest total solar eclipse visible from land this century.
A Once-in-a-Century Sequence, Already Under Way
What makes the 2027 eclipse in Spain remarkable is that it isn’t a one-off. It is the second chapter of an extraordinary trilogy of Iberian eclipses spanning 2026 to 2028—a sequence not seen in more than a century.
The first installment came on August 12, 2026, when the northern half of the Iberian Peninsula and the Balearic Islands—from A Coruna to Palma de Mallorca, passing through Zaragoza and Valencia—witnessed the first total solar eclipse visible in Spain since 1912.
The August 2027 event is the trilogy’s second act, this time sweeping totality across the country’s southernmost reaches.
A third is still to come: an annular eclipse—the classic ring of fire—on January 26, 2028. After that, Spain will not see another total solar eclipse until 2053.
Why This Eclipse Is Exceptionally Rare
The August 2027 eclipse stands out even in this already unusual series.
At its peak, over the Nile Valley, totality will last 6 minutes and 22 seconds—making it the longest total solar eclipse visible from land in the entire 21st century. No eclipse will match that duration until June 3, 2114.
The moon’s shadow first touches down in the Atlantic Ocean, sweeps across the Strait of Gibraltar, traverses northern Africa—Morocco, Algeria, Libya, and Egypt—and continues toward the Arabian Peninsula, on a journey that takes more than five hours from start to finish.
Where Totality Will Be Visible in Spain
In Spain, the path of totality enters from the southwest and covers mainly the province of Cadiz, along with Ceuta and Melilla.
The closer you are to the Strait of Gibraltar, the longer totality lasts. Algeciras gets 4 minutes and 26 seconds of darkness. In Ceuta, it reaches 4 minutes and 48 seconds—the longest duration anywhere in Spain. Melilla sees 4 minutes and 33 seconds.
In the city of Cadiz itself, slightly farther from the central line, totality runs 2 minutes and 54 seconds. In Malaga, at the edge of the path, it shrinks to just 1 minute and 47 seconds.
Move roughly 125 miles north and totality disappears entirely, leaving only a partial eclipse. In other words, exactly where you watch from matters enormously.
The timing also works in observers’ favor. The partial phase begins around 9:40 a.m., and totality arrives between 10:45 and 10:49 a.m., depending on location. By then the sun will be well above the horizon—between 37 and 42 degrees—and the entire event wraps up around noon.
Unlike the 2026 eclipse, which unfolded at dusk with the sun sitting low in the sky, this one takes place in broad daylight, offering significantly better viewing conditions.
How to Prepare
Given the scale of the event, a national committee has already been established to coordinate eclipse-related activities across the country.
Accommodations within the path of totality—especially throughout the province of Cadiz—are already booking up well in advance, just as they did ahead of the 2026 eclipse.
For anyone planning a trip, one practical note bears repeating: looking directly at the sun without protection is only safe during the minutes of totality itself.
Throughout the partial phase—which in Spain lasts more than two hours—certified eclipse glasses that meet the ISO 12312-2 standard are essential. They block nearly all direct solar radiation and are the only safe option outside of totality.
Make It a Trip: Exploring Andalusia
Because totality is concentrated in the province of Cadiz, the area makes a natural base for exploring more of southern Spain.
An eclipse itinerary could easily take in Cadiz itself, one of the oldest cities in Western Europe; Vejer de la Frontera, with its whitewashed hillside streets; the coast of Tarifa, where the Atlantic meets the Mediterranean; and Seville, an easy day trip away.
For those willing to cross the water in pursuit of the longest possible totality, the path continues on the African side of the strait, through Tangier and northern Morocco—an option growing in popularity among seasoned eclipse chasers eager for the extra minutes Africa offers.
Whether you watch from Cadiz, Ceuta, or across the strait, the path of totality on August 2, 2027, will be one of the best places on Earth to look up—if only for a few extraordinary minutes.
