Adailou (Arabic: أديلو) is a town in the Tadjoura region of Djibouti.

Adailou has one of the mildest climates in Djibouti, which is not always passable during the rainy season.

According to tradition, the village is where the ancestor of Adaal, Haral-Maahis, gave birth to his lineage.

Known for its mild climate, Adailou is unusual like Airolaf and Randa in hosting a large camp in the summer, during which life in Tadjoura and Djibouti City is difficult because of the heat.

Summers are hot with June being the hottest month, averaging 34.4 °C or 93.9 °F during the day and 23 °C or 73.4 °F during the night.
