Riyadh sits in the heart of the Arabian Peninsula, surrounded by vast desert that offers some of the most accessible pristine dark skies anywhere. The city's Bortle 8 core gives way to Bortle 2 desert within an hour or two in any direction — the Tuwaiq escarpment and the dunes beyond are popular observing areas. At 24.7°N, the southern sky is well presented, and the extremely dry desert air delivers outstanding transparency and steady seeing. Winter nights are comfortable and crystal clear; even the hot summer brings reliably transparent skies over the desert.
