Although it is crossed by the equator, Kenya hasn't the typical climate of this latitude: changed by the influence of the Indian Ocean and the mountains; the coast is tropical hot and humid, while inside in the Rift Valley is extremely arid. For example Kisumo, near the equator on Lake Victoria, hasn't an equatorial climate: the monthly average ranges from 22 ° in the cold months to 24 ° in hot ones, but retains a high humidity, typical of the equatorial climate and difficult to tolerate for Europeans people.
Precipitations are still concentrated in two periods of the year: the long rains from March to May, and short repeated intense from October to December. In central and eastern regions the rainfall is influenced by the winds and monsoon winds coming from the Indian Ocean, increases on the highest mountains in the east where rainfall exceeds one meter and a half every year: the Elgon, Meru, Kenya and Kilimanjaro. Some plateaus have a climate almost ideal due to the altitude that lowers the temperature: the air is drier, with natural temperature daily changes and an annual average of 14 ° / 19 °.
Each year, the drought severely affecting the northern and eastern areas, with dramatic consequences for livestock and for the population. During rainy seasons, flooding causes more damage, making it difficult to survive, which is compounded by the deterioration of water quality generated by the use of insecticides and fertilizers, pollution from urban and industrial discharges, from deforestation which extends desertification.
