Average daily temperatures in January
January is one of the coolest months in Oman, but everything is relative—and compared to January in much of the northern hemisphere, the climate is mild and comfortable. In Muscat, the capital, daytime highs reach around 77°F (25°C), while nighttime lows drop to 63°F (17°C). The cooler conditions make it an excellent time for outdoor exploration, from the city’s historic sites to its pristine beaches. If you’re wondering why visit Muscat, January gives you plenty of reasons.
In the mountainous regions, such as Jebel Akhdar and Jebel Shams, temperatures are significantly cooler, with daytime highs averaging 59°F (15°C) and nighttime lows dropping to 41°F (5°C). These areas can feel somewhat chilly, especially after sunset, so it pays to pack a warm layer or two.
The desert regions, including the Wahiba Sands and the Empty Quarter, experience more extreme temperature fluctuations. Daytime highs reach around 79°F (26°C), but at night, temperatures can plummet to 50°F (10°C) or lower, making early mornings and evenings quite cool.
Coastal areas along the Arabian Sea, including Salalah, remain warm and pleasant, with highs around 81°F (27°C) and lows near 68°F (20°C). The sea remains relatively warm, making it a great time for water activities such as diving and snorkeling.
Overall, January is one of the most pleasant months to visit Oman, offering comfortable temperatures for sightseeing and outdoor adventures — and often considered the best time to visit Oman.
What about the crowds and cost?
January is peak season in Oman, as travelers flee colder climates for sunshine and warmth. It’s easy to see why Oman is a winter sun destination — think blue skies, beach weather, and cool desert nights. Popular spots like Muscat, Wahiba Sands, and Jebel Akhdar can get busy, and hotels fill up fast.
Top sights like Nizwa Fort and Wadi Shab are especially popular this time of year. They're among the best things to do in Oman, so expect more people around and plan ahead.
Flights, tours, and accommodation are at their most expensive in January. Desert camps and luxury resorts often sell out weeks in advance. The upside? You get great weather and plenty of cultural energy — it’s worth the splurge if you plan it right.
