KENYA’S VEGETATION AND CLIMATE
Kenya’s Weather Today:
Different geographic regions, which are described elsewhere, go in parallel with the great climatic diversity that Kenya is composed of.
The temperatures in Kenya experience little variation throughout the year since it’s an equatorial country.
The average temperatures and rainfall for the different regions are however very different from each other.
Winds and altitude differences are noted to be the major causes of this climatologic diversity.
Wildlife and road conditions are influenced by the rainfall pattern and therefore, it’s very vital. Many roads are flooded and impassable when rains are received.
The Long rainfall between the period of March and June and the Short rains from October to November are the two periods in which the rainy season is divided.
Generally, temperatures in months corresponding to those in the boreal winter like January, February and March, are usually higher.

Kenya’s Vegetation and Climate by region:
Top Rift Valley and Highlands:
Altitude and winds are responsible for the mild and moderate climate in this region generally.
During the boreal summer months, the highest temperatures are 230C and are 26-270C during the boreal winter months in Nairobi, which is 1700m high, 12-150C is the range within which the lowest temperatures lie.
At higher altitudes, temperatures drop as a must.
120C to 180C is the range within which the average temperatures lie, with night temperatures going below 100C in the region of Mount Kenya.
In the Aberdare region, like the Mount Kenya region, the night lows are cold in the rainy season, rainfall is usually in plenty and in the long rains, higher levels are experienced.
The origin of the Savannah, the most peculiar and tropical landscape in this region of the world, as a natural or man-made ecosystem is controverted and it (the Savannah) is nothing other than a transition between rainforest and the arid steppe.
A variety of trees and bush mostly Acacia and Gramineae dominate the savannah, which is mainly a grassland.
A consequence of the several factors’ action is the natural balance of the savannah.
The factors include; Migrations of large herds of herbivores in search for the young pastures rich in salt, fire action, by which overgrowth of trees and bush which would be in competition for sunlight and the soils’ nutrients with grass, is limited and finally the regular rainfall pattern, by which growth of tender pastures is promoted.
The most common and typical species in the savannah are the Acacia genus species growing as tree or bush and belonging to the Mimesa family.
The cylindrical clustering flowers, the leguminous-like fruits, the flat tops, composed of leaves and the hard thorns, are the factors by which Acacias can easily be identified from other species.
The Acacia bark is pretty vital for use in manufacturing pharmaceutical products and dyes, since it’s rich in tannin.
It’s also equally important for animal species like elephants, gerenuks and giraffes because it serves as food to them.
Though highlands do not exceed 3% of the total surface of the country, they preserve the richest extensions of rainforest in Kenya, above 1300 meters.
In the Mount Kenya Region is where the largest patches are.
Largely present are the ferns, conifers, Mediterranean cedars and Junipers of the Podocarpus genus.
Bamboo forests are cited above 2000 meters. Mountain vegetation mainly peat dogs, giant Lobelias, heather and montane prairies predominates at higher altitudes, say above 3000 meters.
Top Lake Victoria Basin:
Altitude say around 1200 meters and most winds emerging from the Great lakes, modulate the climate at the lake Victoria shores.
During day, the temperatures are high compared to the night where they are moderate, with yearly highs of 310C and lows of 170C.
Some patches of tropical rainforest are still evident at the Mount Elgon slopes on the vast part of this territory is where the typical highlands vegetation is located or cited.
Top NE, Nyika [Eastern Highlands] and North:
The roughest climate is experienced in the Northern and North Eastern regions of the country whose reflection is in the arid landscape.
Very little rainfall with yearly levels of about 350mm is experienced.
All throughout the year, temperatures are high and rise up to 370C during the day in the hottest months.
Temperatures usually do not fall below 210Cduring the night.
Unlike in the Northern and North Eastern Regions, temperatures in the Eastern highlands are warm, but a bit lower, approximately 300C in the day and 200C in the night.
In the Northern and North Eastern regions, the vegetation is basically composed of thornbush and is sparsely populated.
Acarcias and tree cacti of the Euphorbia genus are found in the Southern region.
Because of it’s spectacularity, in certain cases growing to 18m high and with tree trunks reaching 9 meters in diameter, the giant Baobab (Adansonia digitata) of the Bombacacea family stands out distinctively.
It’s bark is very important for use in ropes and cloth manufacturing, in addition to which it’s pulpy fruit is good for eating.
In the Northern and NorthEastern regions as well as in the river valleys plus in areas having an alpine-like landscape such as the Taita Hills, the vegetation is more diversely and abundantly populated only at the Oasis.
Semi-deserted Steppes or Deserts make up the vast part of Kenya’s land given the extension of the arid regions.
Top of the Coast of Kenya:
In the Kenyan Indian Ocean Coast, the mean yearly temperatures are about 280C.
As corresponds to the coast’s altitude, it’s weather, generally speaking is humid and warm.
In the period of the boreal winter months, the temperatures are drier and warmer in general terms, with the highest at about 320C and rarely drop lower than 210Cand as well, the storms are frequent.
The coastal region is made the suitable habitat fro tropical vegetation by it’s temperature and humidity conditions.
Some patches of tropical rainforest are still evident along the shores and as well, the mangroves and coconut palm trees grow there.
