Oman (Muscat) – What you should know
Oman has an extreme desert climate with very hot summers and mild winters. In Muscat, temperatures from June to August climb to 36–38°C (97–100°F) as a monthly average — outdoor activities are only possible in the early morning hours. Unlike many other Gulf states, Oman has pronounced topography: the Hajar Mountains even bring occasional summer rain to higher elevations.
The best travel time for Muscat and the coast is November to March: temperatures of typically 22–29°C (72–84°F), clear air and calm seas make snorkelling, whale watching and desert tours possible. October, with a monthly average of 34°C (93°F), is still too hot for extended outdoor activities. In November, humpback whales and dolphins regularly appear off the Omani coast — a spectacular natural spectacle.
The monsoon (Khareef) hits the Dhofar region in southern Oman in summer and transforms the otherwise barren landscape into a green paradise with waterfalls and mist. Salalah in July and August is therefore a popular destination for Omanis and Gulf tourists fleeing the midsummer heat.

The travel year in Oman (Muscat)
October – March
Oman's golden travel window: Muscat at 25–30°C (77–86°F), the wadis and fjords of Musandam turquoise, the Wahiba Sands desert orange-gold at sunset. Camel treks, diving in the Indian Ocean, Mutrah Souq in the early morning.
April – June
Shoulder season: it gets hot, but still bearable. Salalah in the south heralds its khareef monsoon season — the only Arabian city with a green summer.
July – September
High summer in the north, khareef in the south: Muscat in unbearable heat (45°C (113°F)+). Salalah, by contrast, is cool and green thanks to the monsoon — unique on the Arabian Peninsula.
