Somaliland's climate is a mixture of wet and dry conditions. The northern part of the region is hilly, and in many places the altitude ranges between  above sea level. The Awdal, Sahil and Maroodi Jeex (Woqooyi Galbeed) regions are fertile and mountainous, while Togdheer is mostly semi-desert with little fertile greenery around. The Awdal region is also known for its offshore islands, coral reefs and mangroves.
