Best time to visit Oman: Muscat and Salalah

Oman is one of the warmest countries you can travel to from Europe in winter – and one of the hottest in summer. The capital Muscat on the coast and the oasis town of Nizwa inland follow the classic desert rhythm: pleasantly warm from autumn to spring, very hot from May to September. The south around Salalah in the Dhofar region is different: in summer the monsoon brings fog, drizzle and green hills, and many visitors from the Gulf states travel there precisely then. We analysed the weather from 2015 to 2024 at three places.

The short answer

• Best time for a round trip: November to March. Muscat 24 to 29 °C by day, Nizwa 25 to 31 °C, little rain.
• Shoulder months: October and April – still warm to hot at 33 to 36 °C by day, quieter.
• Avoid for the north: May to September. Muscat reaches 36 to 39 °C, Nizwa 38 to 42 °C.
• Salalah: a different calendar. The khareef season from late June to September is green and misty at around 28 °C; winter there is sunny and warm.

Oman's climate: all 12 months

Temperature and rain: monthly averages 2015–2024 from the ERA5 reanalysis (via Open-Meteo), rounded. A grid cell is about 25 km wide. In a desert climate, the monthly rain total is often the result of a few rare storms; individual years can differ a great deal. The khareef drizzle on the mountains behind Salalah is only partly captured by such a coarse grid.

Muscat shows the desert rhythm clearly: from December to February the days are 24 to 26 °C, from May to August 37 to 39 °C, and even the nights then stay at around 30 °C. Inland in Nizwa the days are hotter, but winter nights are cooler at around 15 °C.

Salalah runs against the trend: the warmest month there is May at 32.4 °C, and in July and August, when the rest of the country is at its hottest, the khareef brings it down to 28 to 29 °C.

Oman month by month

November to February

The main season. Muscat is warm at 24 to 29 °C, the sea is pleasant for swimming, and in the desert of the Wahiba Sands the nights are cool. A round trip from Muscat via the wadis to Sur, through the desert to Nizwa and up into the mountains works well now. In the Hajar Mountains, for example on Jebel Akhdar or Jebel Shams, it is considerably cooler, especially at night. Rain is rare, but according to the UK travel advice, wadis are prone to flash flooding after heavy rainfall from October to March.

March and April

Spring gets warm quickly: Muscat climbs from 29 to 34 °C, Nizwa to 36 °C. March is still a good travel month; in April, plan outdoor activities for the morning.

May to September

Summer in the north is extremely hot: Muscat 36 to 39 °C by day with nights around 30 °C and high humidity on the coast, Nizwa over 40 °C. Sightseeing is only practical early in the morning. According to the UK travel advice, tropical cyclones from the Indian Ocean sometimes affect Oman in July and August.

The khareef in Salalah (late June to September)

In summer the south-west monsoon brings low clouds, fog and drizzle to the coast and mountains of Dhofar. The hills around Salalah turn green, waterfalls flow, and the region becomes a popular summer destination for visitors from the Gulf. Oman's Ministry of Heritage and Tourism opened the 2023 khareef season on 21 June and ran it until 21 September. For beach weather this is not the right time; from October to April Salalah is sunny and warm at 27 to 32 °C.

October

Transition month: Muscat still reaches 33.5 °C by day, the evenings become more pleasant. Good for travellers who want to start the season before the busiest weeks.

A classic round trip

Most round trips start in Muscat with the old town, the Muttrah Corniche and the Grand Mosque. Along the coast towards Sur lie wadis such as Wadi Shab, then the route goes into the Wahiba Sands for a night in a desert camp and on to Nizwa with its fort and souq. From there, the mountain roads lead up to Jebel Akhdar and Jebel Shams; for some of them a four-wheel drive is required. A hire car^* is the usual way to travel; Salalah is a separate destination far to the south, reached by domestic flight. Comparing the Gulf in winter? See also the best time to visit Dubai.

How YesTrip helps with this trip

In YesTrip you plan Muscat, the wadis, the desert and Nizwa day by day on one map, so the long drives between them are clear in advance. The forecast for your travel days shows when it gets hot and a wadi hike is better started in the early morning – and warns you of rain, which matters in the wadis. The packing list suggests sun protection, light long clothing and a warm layer for desert nights and the mountains. Travelling as a group, you share the trip and log shared expenses like the hire car and the desert camp.

Before you go
