Rain in Unaizah: What You Need to Know

Unaizah is a historic Najd agricultural oasis town, long known for its palm groves and traditional mudbrick architecture in the old city center. Riyadh sits on the Najd plateau at roughly 600m elevation, in a semi-arid climate with average annual rainfall of just 100-120mm, most of it arriving as sudden convective thunderstorms rather than steady rain.

Rain here is driven by upper-level troughs moving across the Arabian interior, colliding with the plateau's heat to trigger fast-forming, intense storm cells rather than the coastal Red Sea Trough mechanism that dominates Jeddah. Riyadh's flat, heavily urbanized terrain means storm water has nowhere to drain naturally -- wadis (dry riverbeds) that stay empty most of the year can fill and overflow within an hour of a storm starting.
