Dust & air-quality forecast for Riyadh

Riyadh, the Saudi capital, sits inland on the central Nejd plateau rather than on the Gulf coast — geographically closer to the interior desert sources that generate large regional dust events. It is also the largest city in the Gulf by population and the site of some of the region's biggest active construction programs under Saudi Arabia's Vision 2030 push, which puts a lot of outdoor work and outdoor life on the line during a bad-dust stretch.

Nafas forecasts Riyadh's air quality 48 hours ahead, twice a day, from Copernicus CAMS (via Open-Meteo), cross-checked against Sentinel-5P and OpenAQ / public ground stations where coverage exists. The goal is the same plain call given for every city Nafas covers: what's coming, and what to do about it.
