The Somali southward dispersal is among Northeast Africa’s most sustained population movements

Evidence

Folk tradition today offers little information as to the causes of this movement. It would not be unreasonable to conjecture, however, that mounting population pressure, augmented by continued Arab immigration, and perhaps exacerbated by a series of severe droughts, prompted a general Somali movement in search of new pastures. And this was no doubt furthered by the messianic and militant fervour of early Islam. — I.M. Lewis, I. M. Lewis, A Modern History of the Somali_ Nation…, 92 (#expands, via linked claim)

The traditions of migration indicate that in their gradual and by no means co-ordinated movement towards the south the Somali followed two main routes: they descended from the north down the valley of the Shebelle and its tributaries, or along the line of coastal wells on the Indian Ocean littoral. — I.M.
