During the summer months the weather turns intensely hot with temperatures consistently exceeding 40°C, and nighttime lows never falling below 25°C.

This makes the nights an extension of the daytime heat.

Aswan’s Weather History

Aswan formerly known as “Swenet,” was not just a city on the banks of the Nile; it was the southern border of ancient Egypt where Egyptian civilization met with neighboring African kingdoms.

It is said that its name is inspired by the Egyptian goddess “Swenet,” whom the Greeks later associated with “Eileithyia,” the goddess of childbirth.

The Romans called it “Lucina” for the same reason.

Another belief is that its name is derived from the ancient Egyptian symbol for trade demonstrating its importance as a major economic center in ancient times.

For the ancient Egyptians Aswan was more than just a city; It was the starting point always looking south, to the sources of the Nile the source of life. As the southern city in Egypt it was the true beginning of the country.

Its unique location situated on a peninsula extending along the eastern bank of the Nile right at the First Cataract made it a strategic point for boats to cross into the Delta without any natural obstacles.

Aswan was not only famous for its strategic location it was also a treasure trove of Egyptian civilization thanks to its unique quarries which produced the finest stone especially pink granite known as syenite.

This rock was the backbone of the construction of temples obelisks, and colossal statues that still bear witness to the greatness of the pharaohs. From here came the stones that formed the pyramids, temples, and mausoleums where the traces of ancient quarry workers

 who harnessed their strength alongside domesticated animals are still engraved on the rock walls to this day.

Aswan’s Northern Borders

The weather in Aswan has always been hot as this city located at latitude 24° 5′ 23″, was a point of great interest to geographers and scientists in ancient times.

They believed that its unique location placed it directly below the Tropic of Cancer resulting in a rare astronomical phenomenon. On the summer solstice they observed that any stick stuck vertically into the ground casts barely a shadow.

Furthermore at noon the sun was reflected at the bottom of wells as if shining from the core of the earth itself.

Although this phenomenon was not entirely accurate as a slight barely noticeable shadow remained it was enough to pique the curiosity of the Greek scientist Eratosthenes who exploited this observation in one of the greatest scientific achievements in history.

Using the difference in shadow length between Aswan and Alexandria, he was able to calculate the circumference of the Earth with amazing accuracy.
