Geography of Galmudug

From east to west the state rises gently in three broad steps. Along the ocean runs a coastal strip of white dunes and salt flats, in places several kilometres deep, behind the old ports of Hobyo and Harardhere. Inland begins the Mudug–Galgaduud plain, an enormous expanse of red sandy savanna scattered with acacia and thornbush, which carries the great camel herds that define the region. Toward the Ethiopian border the land lifts onto the eastern edge of the Haud plateau, higher, slightly cooler grazing country that Somali pastoralists have crossed with the seasons for centuries.

There are no permanent rivers anywhere in Galmudug. Life depends on deep wells cut into the limestone — many of them ancient — together with hand-dug water pans (balli) and cemented rain cisterns (berkado) that store the two rainy seasons against the long dry months.

The climate is hot and semi-arid to arid, with annual rainfall mostly between 100 and 300 millimetres. The Somali year turns on four seasons: the main Gu rains from roughly April to June, the hot dry Xagaa of July to September on the coast, the shorter Deyr rains of October and November, and the long dry Jilaal from December to March, the hardest season for herds and households alike. Coastal towns are tempered by the sea breeze; inland, daytime temperatures routinely pass 35°C.

Rainfall is famously unreliable. Consecutive failed seasons bring drought — the 2016–17 and 2021–23 droughts hit central Somalia severely — and a good Gu can transform the plains within weeks into green pasture that draws herders from hundreds of kilometres away.

Galmudug's roughly 700-kilometre coastline faces some of the most productive and least exploited waters of the western Indian Ocean, rich in tuna, lobster, and demersal fish. The shore itself alternates between dune fields, rocky headlands, and long empty beaches; Hobyo's dunes, slowly advancing on the old town, are among the most striking landscapes in Somalia.

The savanna carries a hardy dryland ecology: acacia and commiphora woodland, seasonal grasses, and wildlife including dik-dik, gerenuk, warthog, ostrich, and bustard. Decades of conflict and charcoal cutting have pressed hard on trees and game alike, and local administrations have begun — modestly — to restrict charcoal export and protect what remains.
