Topography of Kenya

The geography of Kenya is diverse. Kenya has a coastline on the Indian Ocean, which contains swamps of East African mangroves. Inland are broad plains and numerous hills. Central and Western Kenya is characterized by the Great Rift Valley home to three of Africa's highest mountains, Mount Kenya, Mount Elgon and Kilimanjaro. The Kakamega Forest in western Kenya is relic of an East African rainforest. Much larger is Mau Forest, the largest forest complex in East Africa.

Climate

The climate of Kenya varies by location, from mostly cool every day, to always warm/hot.^[2][3][4] The climate along the coast is tropical. This means rainfall and temperatures are higher throughout the year. At the coastal city Mombasa, the air changes from cool to hot, almost every day (see chart below).^[4] The further inside Kenya, the more arid the climate becomes. An arid climate is nearly devoid of rainfall, and temperature swings widely according to the general time of the day/night. For many areas of Kenya, the daytime temperature rises about 12 °C (53.6 °F), almost every day. ^[2][3][4]

Elevation is the major factor in temperature levels, with the higher areas, on average, as 11°C (20°F) cooler, day or night.^[2][3][4] The many mile-high cities have temperature swings from roughly 50–79 °F (10–26.1 °C). Nairobi, at 1,798 m (5,899 ft) or 1.798 km (1.12 mi), ranges from 49–80 °F (9.4–26.7 °C),^[2] and Kitale, at 1,825 m (5,988 ft) or 1.825 km (1.13 mi), ranges from 51–82 °F (10.6–27.8 °C).^[3] The overnight lows are not like the "Garden of Eden" because, at night, heavy clothes or blankets are needed, in the highlands, when the temperature drops to about 50–54 °F (10–12.2 °C) 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 sealevel 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 7.20 °F,^[2][3][4] cooler in the winter months. Although Kenya is centered at the equator, it shares the seasons of the southern hemisphere: with the warmest summer months in February-March and the coolest winter months in July-August, although only a few degrees cooler. ^[2][3][4]

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 has occurred on the highest mountains.

Terrain

Kenya’s terrain is composed of low plains that rise into central highlands that are, in turn, bisected by the Great Rift Valley.

Elevation extremes

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.

Rivers

The two main rivers are the Galana and the Tana. However, the Ewaso Ng'iro is a very important river supplying water from Mt. Kenya to the northern part of Kenya.

Natural resources

Natural resources that are found on Kenya include limestone, soda ash, salt, gemstones, fluorspar, zinc, diatomite, gypsum, wildlife and hydropower.

Land use

8.01% of the land is arable. Permanent crops occupy 0.97% of the land. Other uses make up the rest of Kenya's land. (2005)

Irrigated land

1030 km² of Kenya' land is irrigated.(2010)

Natural hazards

Natural hazards include recurring drought and flooding during the rainy seasons.

The Environmental issues

Current issues

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 fertilizers; deforestation; soil erosion; desertification and poaching.

International agreements

• Party to: Biodiversity, Climate Change, Desertification, Endangered Species, Law of the Sea, Marine Dumping, Marine Life Conservation, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution (MARPOL 73/78), Wetlands, Whaling
• Signed, but not ratified: none of the selected agreements

Extreme points

This is a list of the extreme points of Kenya, the points that are farther north, south, east or west than any other location.

• Northernmost point - Kalukwakerith mountain, Rift Valley Province*
• Eastern-most point - the tripoint with Ethiopia and Somalia, North Eastern Province
• Southern-most point - the point where the border with Tanzania enters the Indian Ocean, Coast Province
• Western-most point - unnamed headland immediately east of Port Victoria, Nyanza Province

• Note: This is including the disputed Ilemi Triangle region. If this area is excluded then Kenya does not have a northern-most point, the northern border being a straight line
