Total solar eclipse on August 2, 2027

The Moon passes between Earth and the Sun at the New Moon, and its shadow sweeps over the ground from west to east. At the greatest eclipse the Moon's disk is 1.080 times as wide as the Sun's.

The path of totality begins over the Atlantic Ocean. On land it crosses southern Spain and Gibraltar, Morocco, Algeria, Tunisia, Libya, Egypt, Saudi Arabia, Yemen and Somalia. It ends over the Indian Ocean. The greatest point lies at 25.5° N, 33.2° E, in Egypt near Luxor.

Of the 14 cities in the table, 8 lie inside the path and 6 outside it. Outside, the Sun is only partly covered: in Madrid it is 86.2 percent. A city is listed as inside only with at least 60 seconds of totality. It is listed as outside only below 98 percent covered. Algiers, Tripoli and Aswan lie within a few kilometers of the edge of the path. They are not listed, because a few seconds of error could move them in or out.

At the greatest point, totality lasts about 6 minutes 27 seconds. In the cities of the table it runs from about 2 minutes 36 seconds in Sanaa to about 6 minutes 26 seconds in Luxor. The catalog of the Goddard Space Flight Center lists 6 minutes 23 seconds for the longest totality. The calculation here gives 4 seconds more, and in tests the two agree within 10 seconds.

Each row of the table belongs to one city, listed from west to east along the path. First contact is when the partial eclipse starts and last contact is when it ends. Where a time is shown, it is for the city center, rounded to the minute and written in UTC. The "Your time" column gives the moment of greatest eclipse in that city, written for the time zone of your device. A place not in the table can take roughly its start from the nearest city. A city outside the path does not see totality, so its totality cells stay empty and its type gives the share of the Sun covered.

A certified solar filter, such as eclipse glasses marked ISO 12312-2, blocks nearly all sunlight. It is needed in every partial phase, and everywhere outside the path of totality for the whole eclipse. It can come off only while the Sun is completely covered, and it must go back on before the first sunlight returns. The times in the table are rounded to the minute and do not say when to remove it.

On the central line of this eclipse, published by the Goddard Space Flight Center, the middle of totality agrees to about 6 seconds. In the city table of the U.S. Naval Observatory for the total solar eclipse of August 12, 2026, contact times agree within 8 seconds. No published table of city contact times exists for August 2, 2027, so the city rows rest on that method and not on a direct comparison. The calculation runs a few seconds early, and every time is rounded to the minute.
