Best Time for the Oman's Grand Loop
Sweet spot: January, February, March — computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
Winter is Oman's season: 25°C days for wadis and the Grand Canyon of Arabia rim walk.
50°C in the interior — coastal Muscat mornings and air-conditioned souqs only; the desert camp waits for winter.
