In Ethiopia, the climate varies mostly with altitude, and it goes from the hot and arid climate of the lowlands to the cool climate of the plateau. Lying just north of the Equator, the country experiences little variation in temperature throughout the year.
Rainfall is caused by the southwest monsoon, which affects the country from June to September (the rainy season is called Kiremt), but it only affects some areas, namely the plateau and the mountain slopes exposed to the south-west, while in the south-east of the country, there are two rainy periods, though less intense, usually from March to May and in October-November; in the latter area, during some years, the rains don’t occur at all.
The climate is traditionally divided into three main climatic zones: Dega, Weyna Dega and Kolla. The first of these – Dega – refers to coldish, less than temperate zones with altitudes ranging between 2,600 and 3,200m. The second zone – Weyna Dega – is warm, wet and lies below 2,600m.
