The founding of Addis Ababa dates back to 19th century. At the time, the city was a resort town; its weather and abundance of mineral springs attracted nobility of the Ethiopian Empire and led them to establish a permanent settlement here, which later became the empire's capital. The city is now highly developed with a high human development index, and became an important cultural, artistic, and financial center of Ethiopia.[Source]
Constant temperatures year-round, with wetter and somewhat cooler summers.
While Addis Ababa is located near the equator, the city's high elevation moderates its temperatures, making them very constant year-round. However, precipitation varies considerably by each season.
Mid-November to January is the dry season with occasional rains. During this season, the daytime highs usually don't reach 23 °C/73 °F and the nighttime lows can drop to freezing.
From February to May is the short rainy season with warm temperatures and pleasant rainfall. During this period, the difference between the daytime highs and the nighttime lows is relatively smaller compared to the other seasons, with lows ranging from 10 °C/50 °F to 15 °C/59 °F.
From June to mid-September is the long rainy "winter" of the country. Although this period coincides with summer in the northern hemisphere, the temperatures here are lower compared to the other seasons because of frequent rains/hails and the abundance of cloud cover with fewer hours of sunshine. This time of the year is characterised by dark, chilly and wet days and nights.
The long rainy season is followed by autumn — a transitional period between the wet and dry seasons.[Source]
