Al Rass is an agricultural town in Al Qassim province, part of the region's date palm and grain farming economy. 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.
Wet season (November-April): almost all of Riyadh's annual rainfall falls in this window, with spring (March-April) frequently producing the year's most intense storms.
Dry season (May-October): summer in Riyadh is essentially rainless, with extreme heat (regularly exceeding 45°C) and virtually no precipitation for months at a stretch.
