Climate and Weather
The temperature differences are small. The humidity on the coast and in Djibouti, in particular, is very high. The year is divided into two seasons:
The Republic of Djibouti ranks among the countries with a hot semi-arid climate. With the exception of mountainous regions, there is a high heat rarely lower than 22°.
The cool season, from October to April (average 25 °) with an east wind bringing some rains, and which corresponds to a Mediterranean summer.
The hot season, from May to September (average 35°) where two dry winds blow: the Sabo from the south-west and the Khamsin from the north-west.
The months of May and September are the months of transition during which the reversals of the winds take place which causes flat calm, thus increasing the humidity.
