Egypt's land area is approximately 1,001,450 sq km in northeastern Africa. To the north of Egypt is the Mediterranean while Sudan is to the south of its border. Libya shares its western border while the Red Sea and Israel shares its eastern border.

Egypt is mainly a desert country, with the River Nile dividing the country unevenly in two, and the Suez Canal together with the Sinai Peninsula provide a third division. The landscape is mainly made up of flat desert, without any vegetation apart from the few oases that have survived in the Western Desert. Over 90% of the land area is covered by deserts - the Libyan Desert to the west, the Sahara and Nubian Deserts to the south and the Arabian Desert to the east. More than 90% of the population is centered around the River Nile. It is only the Nile valley and the Nile Delta that is both habitable and arable. Narrow strips are also inhabited on the Mediterranean coast and on the African Red Sea coast.

Egypt is mostly hot and dry throughout the year. Milder weather is experienced by places such as Alexandria and the Mediterranean coast whereas the heat in Cairo and other inland areas is unbearable with temperatures rising to as high as 50ēC in some parts of the country. Temperature in the desert is dramatic and can fluctuate up to a difference of 37ēC in a day.

During winter, temperatures can fall to freezing and heavy winter, rain can be expected along the Mediterranean coast. Spring in Egypt is often surrounded by ‘khamsin‘, a predictable hot and bitter wind which brings blinding sand and dust storms. In the desert, the wind can lift sand up to 2 meters from the ground, creating a shifting, billowing layer above the land.



Size: Approximately 1 million square kilometers.

Topography: Four major regions: Nile Valley and Delta, where about 99 percent of population lives; Western Desert; Eastern Desert; and Sinai Peninsula.

Climate: Except for modest amounts of rainfall along Mediterranean coast, precipitation ranges from minimal to nonexistent. Mild winters (November to April) and hot summers (May to October).

Physical Size and Borders

Egypt, covering 1,001,449 square kilometers of land, is about the same size as Texas and New Mexico combined. The country's greatest distance from north to south is 1,024 kilometers, and from east to west, 1,240 kilometers. The country is located in northeastern Africa and includes the Sinai Peninsula (also seen as Sinai), which is often considered part of Asia. Egypt's natural boundaries consist of more than 2,900 kilometers of coastline along the Mediterranean Sea, the Gulf of Suez, the Gulf of Aqaba, and the Red Sea (see fig. 1).

Egypt has land boundaries with Israel, Libya, Sudan, and the Gaza Strip, a Palestinian area formerly administered by Egypt and occupied by Israel since 1967. The land boundaries are generally straight lines that do not conform to geographic features such as rivers. Egypt shares its longest boundary, which extends 1,273 kilometers, with Sudan. In accordance with the Anglo-Egyptian Condominium Agreement of 1899, this boundary runs westward from the Red Sea along the twenty-second parallel, includes the Sudanese Nile salient (Wadi Halfa salient), and continues along the twenty-second parallel until it meets the twenty-fifth meridian. The Sudanese Nile salient, a finger-shaped area along the Nile River (Nahr an Nil) north of the twenty-second parallel, is nearly covered by Lake Nasser, which was created when the Aswan High Dam was constructed in the 1960s. An "administrative" boundary, which supplements the main Egyptian-Sudanese boundary permits nomadic tribes to gain access to water holes at the eastern end of Egypt's southern frontier. The administrative boundary departs from the international boundary in two places; Egypt administers the area south of the twenty-second parallel, and Sudan administers the area north of it.

Egypt shares all 1,150 kilometers of the western border with Libya. This border was defined in 1925 under an agreement with Italy, which had colonized Libya. Before and after World War II, the northern border was adjusted, resulting in the return of the village of As Sallum to Egyptian sovereignty. Egypt shares 255 kilometers of its eastern border in Sinai with Israel and 11 kilometers with the Gaza Strip.

Egypt is divided into twenty-six governorates (sometimes called provinces), which include four city governorates: Alexandria (Al Iskandariyah), Cairo (Al Qahirah), Port Said (Bur Said) and Suez; the nine governorates of Lower Egypt in the Nile Delta region; the eight governorates of Upper Egypt along the Nile River south from Cairo to Aswan; and the five frontier governorates covering Sinai and the deserts that lie west and east of the Nile. All governorates, except the frontier ones, are in the Nile Delta or along the Nile Valley and Suez Canal.

Data as of December 1990


Natural Regions

Egypt is predominantly desert. Only 35,000 square kilometers- -3.5 percent of the total land area--are cultivated and permanently settled. Most of the country lies within the wide band of desert that stretches from Africa's Atlantic Coast across the continent and into southwest Asia. Egypt's geological history has produced four major physical regions: the Nile Valley and Delta, the Western Desert (also known as the Libyan Desert), the Eastern Desert (also known as the Arabian Desert), and the Sinai Peninsula (see fig. 3). The Nile Valley and Delta is the most important region because it supports 99 percent of the population on the country's only cultivable land.

Data as of December 1990


Nile Valley and Delta

The Nile Valley and Delta, the most extensive oasis on earth, was created by the world's second-longest river and its seemingly inexhaustible sources. Without the topographic channel that permits the Nile to flow across the Sahara, Egypt would be entirely desert; the Nile River traverses about 1,600 kilometers through Egypt and flows northward from the Egyptian-Sudanese border to the Mediterranean Sea. The Nile is a combination of three long rivers whose sources are in central Africa: the White Nile, the Blue Nile, and the Atbarah.

The White Nile, which begins at Lake Victoria in Uganda, supplies about 28 percent of the Nile's waters in Egypt. In its course from Lake Victoria to Juba in southern Sudan, the elevation of the White Nile's channel drops more than 600 meters. In its 1,600-kilometer course from Juba to Khartoum, Sudan's capital, the river descends only 75 meters. In southern and central Sudan, the White Nile passes through a wide, flat plain covered with swamp vegetation and slows almost to stagnation.

The Blue Nile, which originates at Lake Tana in Ethiopia, provides an average of 58 percent of the Nile's waters in Egypt. It has a steeper gradient and flows more swiftly than the White Nile, which it joins at Khartoum. Unlike the White Nile, the Blue Nile carries a considerable amount of sediment; for several kilometers north of Khartoum, water closer to the eastern bank of the river is visibly muddy and comes from the Blue Nile, while the water closer to the western bank is clearer and comes from the White Nile.

The much shorter Atbarah River, which also originates in Ethiopia, joins the main Nile north of Khartoum between the fifth and sixth cataracts (areas of steep rapids) and provides about 14 percent of the Nile's waters in Egypt. During the low-water season, which runs from January to June, the Atbarah shrinks to a number of pools. But in late summer, when torrential rains fall on the Ethiopian plateau, the Atbarah provides 22 percent of the Nile's flow.

The Blue Nile has a similar pattern. It contributes 17 percent of the Nile's waters in the low-water season and 68 percent during the high-water season. In contrast, the White Nile provides only 10 percent of the Nile's waters during the highwater season but contributes more than 80 percent during the lowwater period. Thus, before the Aswan High Dam was completed in 1971, the White Nile watered the Egyptian stretch of the river throughout the year, whereas the Blue Nile, carrying seasonal rain from Ethiopia, caused the Nile to overflow its banks and deposit a layer of fertile mud over adjacent fields. The great flood of the main Nile usually occurred in Egypt during August, September, and October, but it sometimes began as early as June at Aswan and often did not completely wane until January.

The Nile enters Egypt a few kilometers north of Wadi Halfa, a Sudanese town that was completely rebuilt on high ground when its original site was submerged in the reservoir created by the Aswan High Dam. As a result of the dam's construction, the Nile actually begins its flow into Egypt as Lake Nasser, which extends south from the dam 320 kilometers to the border and an additional 158 kilometers into Sudan. Lake Nasser's waters fill the area through Lower Nubia (Upper Egypt and northern Sudan) within the narrow gorge between the cliffs of sandstone and granite created by the flow of the river over many centuries. Below Aswan the cultivated floodplain strip widens to as much as twenty kilometers. North of Isna (160 kilometers north of Aswan), the plateau on both sides of the valley rises as high as 550 meters above sea level; at Qina (about 90 kilometers north of Isna) the 300-meter limestone cliffs force the Nile to change course to the southwest for about 60 kilometers before turning northwest for about 160 kilometers to Asyut. Northward from Asyut, the escarpments on both sides diminish, and the valley widens to a maximum of twenty-two kilometers. The Nile reaches the Delta at Cairo.

At Cairo the Nile spreads out over what was once a broad estuary that has been filled by silt deposits to form a fertile, fan-shaped delta about 250 kilometers wide at the seaward base and about 160 kilometers from north to south. The Nile Delta extends over approximately 22,000 square kilometers (roughly equivalent in area to Massachusetts). According to historical accounts from the first century A.D., seven branches of the Nile once ran through the Delta. According to later accounts, the Nile had only six branches by around the twelfth century. Since then, nature and man have closed all but two main outlets: the east branch, Damietta (also seen as Dumyat; 240 kilometers long), and the west branch, Rosetta (235 kilometers long). Both outlets are named after the ports located at their mouths. A network of drainage and irrigation canals supplements these remaining outlets. In the north near the coast, the Delta embraces a series of salt marshes and lakes; most notable among them are Idku, Al Burullus, and Manzilah.

The fertility and productivity of the land adjacent to the Nile depends largely on the silt deposited by floodwaters. Archaeological research indicates that people once lived at a much higher elevation along the river than they do today, probably because the river was higher or the floods more severe. The timing and the amount of annual flow were always unpredictable. Measurements of annual flows as low as 1.2 billion cubic meters and as high as 4.25 billion cubic meters have been recorded. For centuries Egyptians attempted to predict and take advantage of the flows and moderate the severity of floods.

The construction of dams on the Nile, particularly the Aswan High Dam, transformed the mighty river into a large and predictable irrigation ditch. Lake Nasser, the world's largest artificial lake, has enabled planned use of the Nile regardless of the amount of rainfall in Central Africa and East Africa. The dams have also affected the Nile Valley's fertility, which was dependent for centuries not only on the water brought to the arable land but also on the materials left by the water. Researchers have estimated that beneficial silt deposits in the valley began about 10,000 years ago. The average annual deposit of arable soil through the course of the river valley was about nine meters. Analysis of the flow revealed that 10.7 million tons of solid matter passed Cairo each year. Today the Aswan High Dam obstructs most of this sediment, which is now retained in Lake Nasser. The reduction in annual silt deposits has contributed to rising water tables and increasing soil salinity in the Delta, the erosion of the river's banks in Upper Egypt, and the erosion of the alluvial fan along the shore of the Mediterranean Sea.

Western Desert

The Western Desert covers about 700,000 square kilometers (equivalent in size to Texas) and accounts for about two-thirds of Egypt's land area. This immense desert to the west of the Nile spans the area from the Mediterranean Sea south to the Sudanese border. The desert's Jilf al Kabir Plateau has an altitude of about 1,000 meters, an exception to the uninterrupted territory of basement rocks covered by layers of horizontally bedded sediments forming a massive plain or low plateau. The Great Sand Sea lies within the desert's plain and extends from the Siwah Oasis to Jilf al Kabir. Scarps (ridges) and deep depressions (basins) exist in several parts of the Western Desert, and no rivers or streams drain into or out of the area.

The government has considered the Western Desert a frontier region and has divided it into two governorates at about the twenty-eighth parallel: Matruh to the north and New Valley (Al Wadi al Jadid) to the south. There are seven important depressions in the Western Desert, and all are considered oases except the largest, Qattara, the water of which is salty. The Qattara Depression is approximately 15,000 square kilometers (about the size of Connecticut and Rhode Island) and is largely below sea level (its lowest point is 133 meters below sea level). Badlands, salt marshes, and salt lakes cover the sparsely inhabited Qattara Depression.

Limited agricultural production, the presence of some natural resources, and permanent settlements are found in the other six depressions, all of which have fresh water provided by the Nile or by local groundwater. The Siwah Oasis, close to the Libyan border and west of Qattara, is isolated from the rest of Egypt but has sustained life since ancient times. The Siwa's cliff-hung Temple of Amun was renowned for its oracles for more than 1,000 years. Herodotus and Alexander the Great were among the many illustrious people who visited the temple in the pre-Christian era.

The other major oases form a topographic chain of basins extending from the Al Fayyum Oasis (sometimes called the Fayyum Depression) which lies sixty kilometers southwest of Cairo, south to the Bahriyah, Farafirah, and Dakhilah oases before reaching the country's largest oasis, Kharijah. A brackish lake, Birkat Qarun, at the northern reaches of Al Fayyum Oasis, drained into the Nile in ancient times. For centuries sweetwater artesian wells in the Fayyum Oasis have permitted extensive cultivation in an irrigated area that extends over 1,800 square kilometers.

Eastern Desert

The topographic features of the region east of the Nile are very different from those of the Western Desert. The relatively mountainous Eastern Desert rises abruptly from the Nile and extends over an area of approximately 220,000 square kilometers (roughly equivalent in size to Utah). The upward-sloping plateau of sand gives way within 100 kilometers to arid, defoliated, rocky hills running north and south between the Sudan border and the Delta. The hills reach elevations of more than 1,900 meters. The region's most prominent feature is the easterly chain of rugged mountains, the Red Sea Hills, which extend from the Nile Valley eastward to the Gulf of Suez and the Red Sea. This elevated region has a natural drainage pattern that rarely functions because of insufficient rainfall. It also has a complex of irregular, sharply cut wadis that extend westward toward the Nile.

The Eastern Desert is generally isolated from the rest of the country. There is no oasis cultivation in the region because of the difficulty in sustaining any form of agriculture. Except for a few villages on the Red Sea coast, there are no permanent settlements. The importance of the Eastern Desert lies in its natural resources, especially oil (see Energy , ch. 3). A single governorate, the capital of which is at Al Ghardaqah, administers the entire region.

Sinai Peninsula

This triangular area covers about 61,100 square kilometers (slightly smaller than West Virginia). Similar to the desert, the peninsula contains mountains in its southern sector that are a geological extension of the Red Sea Hills, the low range along the Red Sea coast that includes Mount Catherine (Jabal Katrinah), the country's highest point--2,642 meters. The Red Sea is named after these mountains, which are red.

The southern side of the peninsula has a sharp escarpment that subsides after a narrow coastal shelf that slopes into the Red Sea and the Gulf of Aqaba. The elevation of Sinai's southern rim is about 1,000 meters. Moving northward, the elevation of this limestone plateau decreases. The northern third of Sinai is a flat, sandy coastal plain, which extends from the Suez Canal into the Gaza Strip and Israel.

Before the Israeli military occupied Sinai during the June 1967 War (Arab-Israeli war, also known as the Six-Day War), a single Egyptian governorate administered the whole peninsula. By 1982 after all of Sinai was returned to Egypt, the central government divided the peninsula into two governorates. North Sinai has its capital at Al Arish and the South Sinai has its capital in At Tur.

Data as of December 1990



Throughout Egypt, days are commonly warm or hot, and nights are cool. Egypt has only two seasons: a mild winter from November to April and a hot summer from May to October. The only differences between the seasons are variations in daytime temperatures and changes in prevailing winds. In the coastal regions, temperatures range between an average minimum of 14° C in winter and an average maximum of 30° C in summer.

Temperatures vary widely in the inland desert areas, especially in summer, when they may range from 7° C at night to 43° C during the day. During winter, temperatures in the desert fluctuate less dramatically, but they can be as low as 0° C at night and as high as 18° C during the day.

The average annual temperature increases moving southward from the Delta to the Sudanese border, where temperatures are similar to those of the open deserts to the east and west. In the north, the cooler temperatures of Alexandria during the summer have made the city a popular resort. Throughout the Delta and the northern Nile Valley, there are occasional winter cold spells accompanied by light frost and even snow. At Aswan, in the south, June temperatures can be as low as 10° C at night and as high as 41° C during the day when the sky is clear.

Egypt receives fewer than eighty millimeters of precipitation annually in most areas. Most rain falls along the coast, but even the wettest area, around Alexandria, receives only about 200 millimeters of precipitation per year. Alexandria has relatively high humidity, but sea breezes help keep the moisture down to a comfortable level. Moving southward, the amount of precipitation decreases suddenly. Cairo receives a little more than one centimeter of precipitation each year. The city, however, reports humidity as high as 77 percent during the summer. But during the rest of the year, humidity is low. The areas south of Cairo receive only traces of rainfall. Some areas will go years without rain and then experience sudden downpours that result in flash floods. Sinai receives somewhat more rainfall (about twelve centimeters annually in the north) than the other desert areas, and the region is dotted by numerous wells and oases, which support small population centers that formerly were focal points on trade routes. Water drainage toward the Mediterranean Sea from the main plateau supplies sufficient moisture to permit some agriculture in the coastal area, particularly near Al Arish.

A phenomenon of Egypt's climate is the hot spring wind that blows across the country. The winds, known to Europeans as the sirocco and to Egyptians as the khamsin, usually arrive in April but occasionally occur in March and May. The winds form in small but vigorous low-pressure areas in the Isthmus of Suez and sweep across the northern coast of Africa. Unobstructed by geographical features, the winds reach high velocities and carry great quantities of sand and dust from the deserts. These sandstorms, often accompanied by winds of up to 140 kilometers per hour, can cause temperatures to rise as much as 20° C in two hours. The winds blow intermittently and may continue for days, cause illness in people and animals, harm crops, and occasionally damage houses and infrastructure.
