December is the first true winter month : temperatures are mild during the day, and nights start to be fresh inland.

In the montain, it starts to be fresh during the day and cold at night, mainly above 2000m and on the northern slope which see little sun.

Winter crops (garlic, onions, wheat, beans, chickpeas, vegetables) are already in the fields : they just need watering (but with cooler temperatures, water needs are less frequent…) and weeding… It’s often the time of the year when people clean the palm trees (remove dry leaves, recut the older ones, etc…) and gardens in general…

* in the desert (above all Rub Al Khali, and to a lesser extent in Wahiba Sands), temperatures rise higher during the day, and drop lower at night (~5-10°C gap, sometimes more).
Bad weather in Northern Oman bring sudden drop in temperatures inland.

** in the montains, above all in winter (when the sun is lower), there can be big difference between northern slopes, which see less sun, and southern slopes which are continuously exposed. The same apply to steep-sided places.


Best outdoor activities to do in Oman in December

It’s probably the best month for mountain hiking : sun is lower and smoother, and the steep northern mountain slopes remain under the shade most of the day. Night might be very cold high in the mountain ; you should plan to bring warmer clothes. If you plan to camp, a warm sleeping bag is necessary (Comfort -5°C).

If you want to enjoy long stays in the desert and desert walks, it’s the perfect month (along with January)!

The seaside is very pleasant : we gladly spend full days at the beach and hike along the coast. The water in the Sea of Oman might start to be a bit fresh ; the Indian Ocean always stay at nice temperature.

Finaly, camping in the desert, on the beach, in the lowlands, or in the lowhills is very enjoyable : temperatures are perfect! Higher in the mountains, it’s cold at night and you should plan warm clothes and a good sleeping bag (Comfort -5°C)!


Outdoor activities to avoid in December in Oman

The water of the wadis starts to be a bit cold : we still enjoy swimming in the natural pools, but getting in the water take more time… For canyoning and aquatic hiking, we start to prefer wearing wetsuit (at least shorty ones).

Visiting one or two aquatic wadis is still a good idea, but it’s not the best season for focussing on wadis
