The Geography of Kenya is diverse, varying amongst its 47 counties. Kenya has a coastline on the Indian Ocean, which contains swamps of East African mangroves. Inland are broad plains and numerous hills. Kenya borders South Sudan to the northwest, Uganda to the west, Somalia to the east, Tanzania to the south, and Ethiopia to the north. Kenya currently faces border disputes with South Sudan over the Ilemi Triangle and with Somalia over Jubbaland where, if the Somalian Government gives it up, it could be a new part of Kenya, which would bring the total land area of Kenya to approximately 692,939 km2.
Central and Western Kenya is characterized by the Kenyan Rift Valley and central Province home to the highest mountain, Mount Kenya and Mount Elgon on the border between Kenya and Uganda. The Kakamega Forest in western Kenya is a relic of an East African rainforest. Much bigger is Mau Forest, the largest forest complex in East Africa.
Much of the western two-thirds of the country consists of the Pliocene–Pleistocene volcanics deposited on Precambrian basement rocks. [2] The southeast corner of the country is underlain by sediments of the Karoo System of Permian to Late Triassic age and a strip of Jurassic age sediments along the coast in the Mombasa area. [2] The Anza trough is a NW–SE trending Jurassic rift extending from the Indian Ocean coast to the Sudan northwest of Lake Turkana. The Anza Rift resulted from the break–up of Gondwana. [2] [3]
The climate of Kenya varies by location, from mostly cool every day, to always warm/hot by mid afternoon. [4] [5] [6] The climate along the coast is tropical. This means rainfall and temperatures are higher than inland throughout the year. At the coastal cities, Mombasa, Lamu and Malindi, the air temperature changes from cool to hot, almost every day. (See chart below). [6]
The further inland one is in Kenya, the more arid the climate becomes. An extremely arid climate is nearly devoid of rainfall, and temperature varies widely according to the general time of the day/night. For many areas of Kenya, the daytime temperature rises about 12 °C (corresponding to a rise of about 22 °F), almost every day. [4] [5] [6]
Elevation is the major factor in temperature levels, with the higher areas, on average, about 11 °C (20 °F) cooler, day or night. [4] [5] [6] The many cities over a kilometre in elevation have temperature swings from roughly 10–26 °C (50–79 °F). Nairobi, at 1,798 m (5,899 ft), ranges from 9–27 °C (49–80 °F), [4] and Kitale, at 1,825 m (5,988 ft), ranges from 11–28 °C (51–82 °F). [5] At night, heavy clothes or blankets are needed, in the highlands, when the temperature drops to about 10–12 °C (50–54 °F) every night.
At lower altitudes, the increased temperature is like day and night, literally: like starting the morning at the highland daytime high, and then adding the heat of the day, again. Hence, the overnight low temperatures near sea level are nearly the same as the high temperatures of the elevated Kenyan highlands. However, locations along the Indian Ocean have more moderate temperatures, as a few degrees cooler in the daytime, such as at Mombasa (see chart below).
There are slight seasonal variations in temperature, of 4 °C or 7.2 °F, [4] [5] [6] cooler in the winter months. Although Kenya is centred at the equator, it shares the seasons of the Southern Hemisphere: with the warmest summer months in December–March and the coolest winter months in June–August, again with differences in temperature varying by location within the country. [4] [5] [6]
On the high mountains, such as Mount Kenya, Mount Elgon and Kilimanjaro, the weather can become bitterly cold for most of the year. Some snowfall occurs on the highest mountains.

Climate change is posing an increasing threat to global socioeconomic development and environmental sustainability. [10] Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. [10] Climate change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.
The effects of these climatic changes have made already existing challenges with water security, food security and economic growth even more difficult. Harvests and agricultural production which account for about 33% [11] of total Gross Domestic Product (GDP) [12] are also at risk. The increased temperatures, rainfall variability in arid and semi-arid areas, and strong winds associated with tropical cyclones have combined to create favourable conditions for the breeding and migration of pests. [13] An increase in temperature of up to 2.5 °C by 2050 is predicted to increase the frequency of extreme events such as floods and droughts. [10]
Hot and dry conditions in Arid and Semi-Arid Lands (ASALs) make droughts or flooding brought on by extreme weather changes even more dangerous. Coastal communities are already experiencing sea level rise and associated challenges such as saltwater intrusion. [10] Lake Victoria, Lake Turkana and other lakes have significantly increased in size between 2010 and 2020 [14] flooding lakeside communities. [15] All these factors impact at-risk populations like marginalized communities, women and the youth. [12]
Kenya's terrain is composed of low plains that rise into central highlands that are, in turn, bisected by the Great Rift Valley. There is also a fertile plateau in the west of the country.
The lowest point on Kenya is at sea level on the Indian Ocean. The highest point on Kenya is 5,199 meters above sea level at Mount Kenya.
The notable rivers in Kenya are the Athi-Galana-Sabaki River, which at a total length of about 390 kilometers while draining an area of about 70,000 square kilometers, is the second longest river in the country, the Tana River, the longest river in the country at a total length of just over 1000 kilometers, covering a catchment area of over 100,000 square kilometers, and the Nzoia River, which is a 257-kilometre-long (160 mi) river, rising from Mount Elgon, which flows south.
Natural resources that are found in Kenya include: limestone, soda ash, salt, gemstones, fluorite, zinc, diatomite, oil, titanium, gas, gold, gypsum, wildlife and hydropower.
9.8% of the land is arable; permanent crops occupy 0.9% of the land, permanent pasture occupies 37.4% of the land; forest occupies 6.1% of the land. Other uses make up the rest of Kenya's land. This is as of 2011.
1,032 km2 of Kenyan land was irrigated in 2003.
30.7 km3 (2011)
Natural hazards include recurring drought and flooding during the rainy seasons.
There is limited volcanic activity in the country. Barrier Volcano (elev. 1,032 m) last erupted in 1921. Several others have been historically active (see List of volcanoes in Kenya).
Current issues that threaten the environment at the moment include water pollution from urban and industrial wastes; degradation of water quality from the increased use of pesticides and fertilisers; deforestation; water hyacinth infestation in Lake Victoria; soil erosion; desertification; and poaching.
This is a list of the extreme points of Kenya, the points that are further north, south, east or west than any other location.
The Democratic Republic of the Congo (DRC) is the largest country of sub-Saharan Africa, occupying some 2,344,858 square kilometres (905,355 sq mi). Most of the country lies within the vast hollow of the Congo River basin. The vast, low-lying central area is a plateau-shaped basin sloping toward the west, covered by tropical rainforest and criss-crossed by rivers. The forest center is surrounded by mountainous terraces in the west, plateaus merging into savannas in the south and southwest. Dense grasslands extend beyond the Congo River in the north. High mountains of the Ruwenzori Range are found on the eastern borders with Rwanda and Uganda.
Djibouti is a country in the Horn of Africa. It is bordered by Eritrea in the north, Ethiopia in the west and south, and Somalia in the southeast. To the east is its coastline on the Red Sea and the Gulf of Aden. Rainfall is sparse, and most of the territory has a semi-arid to arid environment. Lake Assal is a saline lake which lies 155 m (509 ft) below sea level, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. Djibouti has the fifth smallest population in Africa. Djibouti's major settlements include the capital Djibouti City, the port towns of Tadjoura and Obock, and the southern cities of Ali Sabieh and Dikhil. It is the forty-six country by area in Africa and 147st largest country in the world by land area, covering a total of 23,200 km2 (9,000 sq mi), of which 23,180 km2 (8,950 sq mi) is land and 20 km2 (7.7 sq mi) is water.
Morocco is the northwesternmost country which spans from the Mediterranean Sea and Atlantic Ocean on the north and the west respectively, into large mountainous areas in the interior, to the Sahara desert in the far south. Morocco is a Northern African country, located in the extreme northwest of Africa on the edge of continental Europe. The Strait of Gibraltar separates Spain from Morocco with a 13 kilometres (8.1 mi) span of water. Morocco borders the North Atlantic Ocean to the west, and the western Mediterranean Sea to the north, and has borders with Algeria and disputed Western Sahara.
The geography of Mozambique consists mostly of coastal lowlands with uplands in its center and high plateaus in the northwest. There are also mountains in the western portion. The country is located on the east coast of southern Africa, directly west of the island of Madagascar. Mozambique has a tropical climate with two seasons, a wet season from October to March and a dry season from April to September.
Senegal is a coastal West African nation located 14 degrees north of the equator and 14 degrees west of the Prime Meridian. The country's total area is 196,190 km2 of which 192,000 km2 is land and 4,190 km2 is water.
Tanzania comprises many lakes, national parks, and Africa's highest point, Mount Kilimanjaro. Northeast Tanzania is mountainous, while the central area is part of a large plateau covered in grasslands. The country also contains the southern portion of Lake Victoria on its northern border with Uganda and Kenya.
Zambia is a landlocked country located in Southern Africa, to the east of Angola. It has a total area of 752,618 square kilometres, of which 9 220 km2 is water.
Malawi is a landlocked country in southeast Africa. It is wholly within the tropics; from about 9°30S at its northernmost point to about 17°S at the southernmost tip. The country occupies a thin strip of land between Zambia and Mozambique, extending southwards into Mozambique along the valley of the Shire River. In the north and north east it also shares a border with Tanzania. Malawi is connected by rail to the Mozambican ports of Nacala and Beira. It lies between latitudes 9° and 18°S, and longitudes 32° and 36°E.
Somalia is a country located in the Horn of Africa which officially consists of the intra-46th meridian east territory, the seven federal member states, namely Galmudug, Hirshabelle, Jubaland, South West, Puntland, and the municipality of Benadir. It is bordered by Ethiopia to the west, the Gulf of Aden to the north, the Somali Sea and Guardafui Channel to the east, and Kenya to the southwest. With a land area of 637,657 square kilometers, Somalia's terrain consists mainly of plateaus, plains and highlands. Its coastline is more than 3,333 kilometers in length, the longest of mainland Africa. It has been described as being roughly shaped "like a tilted number seven".
Rift Valley Province of Kenya, bordering Uganda, was one of Kenya's eight provinces, before the 2013 Kenyan general election. Rift Valley Province was the largest and one of the most economically important provinces in Kenya. It was dominated by the Kenya Rift Valley which passes through it and gives the province its name. According to the 2009 Census, the former province covered an area of 182,505.1 square kilometres and would have had a population of 10,006,805, making it the largest and most populous province in the country. The bulk of the provincial population inhabited a strip between former Nairobi and Nyanza Province. The capital was the town of Nakuru.
Kenya, officially the Republic of Kenya, is a country in East Africa. With a population of more than 47.6 million in the 2019 census, Kenya is the 28th-most-populous country in the world and 7th most populous in Africa. Kenya's capital and largest city is Nairobi, while its oldest and second-largest city, is the major port city of Mombasa, situated on Mombasa Island in the Indian Ocean and the surrounding mainland. Mombasa was the capital of the British East Africa Protectorate, which included most of what is now Kenya and southwestern Somalia, from 1889 to 1907. Other important cities include Kisumu and Nakuru. Kenya is bordered by South Sudan to the northwest, Ethiopia to the north, Somalia to the east, Uganda to the west, Tanzania to the south, and the Indian Ocean to the southeast. Kenya's geography, climate and population vary widely, ranging from cold snow-capped mountaintops with vast surrounding forests, wildlife and fertile agricultural regions to temperate climates in western and rift valley counties and further on to dry less fertile arid and semi-arid areas and absolute deserts.
The Afrotropical realm is one of the Earth's eight biogeographic realms. It includes Sub-Saharan Africa, the southern Arabian Peninsula, the island of Madagascar, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region.
The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. The series includes Lake Victoria, the second-largest freshwater lake in the world by area; Lake Tanganyika, the world's second-largest freshwater lake by volume and depth; Lake Malawi, the world's eighth-largest freshwater lake by area; and Lake Turkana, the world's largest permanent desert lake and the world's largest alkaline lake. Collectively, they contain 31,000 km3 (7,400 cu mi) of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planet's unfrozen surface fresh water. The large rift lakes of Africa are the ancient home of great biodiversity, and 10% of the world's fish species live in this region.
The Ilemi Triangle, sometimes called only Ilemi, is a disputed area in East Africa, claimed by both Kenya and South Sudan. Arbitrarily defined, it measures about 11,000 square kilometres (4,200 sq mi). The term "Ilemi" may more accurately be transcribed as "Elemi" in the Didinga language, signifying acceptance. This suggest that, in Didinga history, the region became favorable when they arrived, evidenced by the thriving health of the cattle that accepted the local vegetation, indicating a symbiotic relationship between the cattle's well-being and the area. The territory is claimed by South Sudan and Kenya. The territory also borders Ethiopia and, despite use and trespass into the triangle by border tribes from within Ethiopia, the Ethiopian government has not made any official claim on the area, instead agreeing that the land was Sudanese territory in the 1902, 1907, and 1972 treaties.
Environmental issues in Kenya include deforestation, soil erosion, desertification, water shortage and degraded water quality, flooding, poaching, and domestic and industrial pollution.
The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-arid climate, the desert climate, the humid subtropical climate, and the subtropical highland climate. Temperate climates are rare across the continent except at very high elevations and along the fringes. In fact, the climate of Africa is more variable by rainfall amount than by temperatures, which are consistently high. African deserts are the sunniest and the driest parts of the continent, owing to the prevailing presence of the subtropical ridge with subsiding, hot, dry air masses. Africa holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, the highest sunshine duration, and more.
The greater Turkana Basin in East Africa determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia. The deepest point of the basin is the endorheic Lake Turkana, a brackish soda lake with a very high ecological productivity in the Gregory Rift.
Lake Suguta is a former lake in Africa. It formed in the Suguta Valley, which is part of the East African Rift, south of Lake Turkana during the Holocene African humid period.
Climate change is posing an increasing threat to global socioeconomic development and environmental sustainability. Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. Climate change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.
The rainfall patterns during the peak growing season of March, April and May have been changing over the past few decades in the province of Rift Valley, Kenya. Since the 1970s, rainfall during this season has increased in quantity but decreased in the number of days rained. This has resulted in an increase of rain intensity.
Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...
"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.
