Ramadan sits well behind by May 2026, so daytime dining resumes fully. The Sultan Qaboos Grand Mosque remains open with cool marble halls acting as reprieve.

May 2026 offers deep-discount rates at Chedi, W Muscat and Kempinski Al Mouj (up to 45% off peak), making it viable for heat-resistant travelers or those focused on Jebel Akhdar plateau. Book pre-dawn desert excursions and after-sunset city walks. Families should avoid this month unless committed to indoor and highland itineraries. Diving liveaboards from Musandam launch weekly.
Mutrah Corniche at sunset walks past dhows still built by hand in Sur, three hours south.
