Geography
[edit]
A satellite view of Nairobi, 2004
Nairobi is situated at 1°09′S 36°39′E / 1.150°S 36.650°E / -1.150; 36.650 (Nairobi, Kenya) and 1°27′S 37°06′E / 1.450°S 37.100°E / -1.450; 37.100 (Nairobi, Kenya) and occupies 696 square kilometres (270 sq mi).
Nairobi is situated between the cities of Kampala and Mombasa. As Nairobi is adjacent to the eastern edge of the Rift Valley, minor earthquakes and tremors occasionally occur. The Ngong Hills, located to the west of the city, are the most prominent geographical feature of the Nairobi area. Mount Kenya is situated north of Nairobi, and Mount Kilimanjaro is towards the south-east.
The Nairobi River and its tributaries traverse through the Nairobi County and join the larger River Athi on the eastern edge of the county.
Nobel Peace Prize laureate Wangari Maathai fought fiercely to save the indigenous Karura Forest in northern Nairobi, which was under threat of being replaced by housing and other infrastructure.
Nairobi's western suburbs stretch all the way from the Kenyatta National Hospital in the south to the UN headquarters at Gigiri suburb in the north, a distance of about 20 kilometres (12 mi). The city is centred on the City Square, which is located in the Central Business District. The Kenyan Parliament buildings, the Holy Family Cathedral, Nairobi City Hall, Nairobi Law Courts, and the Kenyatta Convention Centre all surround the square.
Climate[edit]
Rain clouds over estates, December 2019
Under the Köppen climate classification, Nairobi has a subtropical highland climate (Cwb). At 1,795 metres (5,889 ft) above sea level, evenings may be cool, especially in the June/July season, when the temperature can drop to 9 °C (48 °F). The sunniest and warmest part of the year is from December to March, when temperatures average in the high-twenties Celsius during the day. The mean maximum temperature for this period is 28 °C (82 °F).
There are rainy seasons, but rainfall can be moderate. The cloudiest part of the year is just after the first rainy season, when, until September, conditions are usually overcast with drizzle. As Nairobi is situated close to the equator, the differences between the seasons are minimal. The seasons are referred to as the wet season and dry season. The timing of sunrise and sunset varies little throughout the year for the same reason.

Nairobi metropolitan region[edit]
Nairobi is found within the Greater Nairobi Metropolitan region, which consists of parts of 5 out of 47 counties in Kenya, which generate about 40% of the entire nation's GDP as per 2022 data by the Kenya National Bureau of Statistics. Nairobi County on its own contributes to 27.5% of the country's GDP according to the same report while Kiambu county comes second with 5.9%.
Districts and neighbourhoods[edit]
Nairobi southern suburbs,2003
Nairobi is divided into a series of constituencies, with each being represented by members of Parliament in the National Assembly. The initial constituencies before the 2010 constitution which led to the county electoral boundaries being redrawn were: Makadara, Kamukunji, Starehe, Langata, Dagoretti, Westlands, Kasarani, and Embakasi. The new electoral boundaries after this were revised to Embakasi North, Embakasi South, Embakasi Central, Embakasi East, Embakasi West, Makadara, Kamukunji, Starehe, Mathare, Westlands, Dagoretti North, Dagoretti South, Langata, Kibra, Ruaraka, Roysambu and Kasarani.
The main administrative divisions of Nairobi are Central, Dagoretti, Embakasi, Kasarani, Kibera, Makadara, Pumwani, and Westlands. Most of the upmarket suburbs are situated to the west and north-central of Nairobi, where most European settlers resided during the colonial times AKA 'Ubabini'. These include Karen, Langata, Lavington, Gigiri, Muthaiga, Brookside, Spring Valley, Loresho, Kilimani, Kileleshwa, Hurlingham, Runda, Kitisuru, Nyari, Kyuna, Lower Kabete, Westlands, and Highridge, although Kangemi, Kawangware, and Dagoretti are lower income areas close to these affluent suburbs. The city's colonial past is commemorated by many English place-names.
Most lower-middle and upper-middle income neighbourhoods are located in the north-central areas, such as Highridge, Parklands, Ngara, Pangani, and areas to the southwest and southeast of the metropolitan area near the Jomo Kenyatta International Airport. The most notable ones include Avenue Park, Fedha, Pipeline, Donholm, Greenfields, Nyayo, Taasia, Baraka, Nairobi West, Madaraka, Siwaka, South B, South C, Mugoya, Riverbank, Hazina, Buru Buru, Uhuru, Harambee Civil Servants', Akiba, Kimathi, Pioneer, and Koma Rock to the centre-east and Kasarani to the northeast area, among others.
The low and lower-income estates are located mainly in far eastern Nairobi. These include, Umoja, Kariokor, Dandora, Kariobangi, Kayole,Njiru, Chokaa, Ruai, Kamulu, Embakasi, and Huruma. Kitengela suburb, though located further southeast, Ongata Rongai and Kiserian further southwest, and Ngong/Embulbul suburbs, also known as 'Diaspora' to the far west are considered part of the Greater Nairobi Metropolitan area. More than 90% of Nairobi residents work within the Nairobi Metropolitan area, in the formal and informal sectors. Many Somali immigrants have also settled in Eastleigh, nicknamed "Little Mogadishu". A complete list of Nairobi postal codes by area and constituency is available online.
