Average temperature across Oman in December.
Muscat, Sohar, Barka
Wintry nights in December are crisp along the coast with daytime highs in the low 20s°C and cooler evenings that can feel chilly near the waterfront. Rain becomes more frequent in stronger winter systems, occasionally grounding small boat trips; the old town is atmospheric under clear, cool skies. Pack layers and a waterproof shell for unpredictable showers.
Khasab, Dibba, fjords & dhow cruises
Winters in December are cool and often windy, with daytime highs in the high teens to low 20s°C and occasional rainy squalls from passing systems. Fjord cruises still run but pack warm layers and waterproofs for early mornings on deck, as temperatures fall sharply after sunset. Expect quieter towns and better deals on private charters.
Jebel Akhdar, Jebel Shams, Nizwa
December nights are cold and daytime conditions are brisk and clear, making high-elevation viewpoints excellent for photography; temperatures at summit lodges can be at or below freezing after dark. Occasional winter storms may deposit sleet at the highest elevations, briefly closing some tracks. Pack serious cold-weather gear if you plan to sleep outdoors or trek above 2,000 m.
Sharqiyah Sands, desert wadis, Ras al Hadd approaches
December delivers crisp desert mornings and cool nights that can be cold in camps, while daytime temperatures remain pleasant in the low 20s°C. The clear skies and gentle wind make it an inviting month for overnight desert stays and off-road exploration. Pack warm insulated clothing for night and a windproof shell for occasional sand-laden gusts.
Salalah, Mirbat, khareef monsoon coast
December cools to comfortable daytime temperatures in the low to mid-20s°C with clear skies and calm waters that suit diving and coastal drives. Nights are mild and dryer, and the region is quieter than during khareef when local visitors are most numerous. Pack a light jacket for breezy evenings and a bathing suit for the warm daytime seas.
National celebrations are prominent in November; the winter season hosts several public events and exhibitions in Muscat and other cities.
