Muscat in May — Full Picture
May in Muscat is the start of the brutal summer — around 39°C/28°C (102°F/82°F), bone-dry (about 5mm), and intense, with extreme UV.
This is low season. Hotel rates fall sharply and the city is quiet, which suits travelers chasing value who are happy to organise their day around the heat: early-morning or evening outdoors, midday firmly indoors in the air-conditioning. The sea is warm but the beach is best at the day's edges.
Wadi hikes and desert camping are punishing now and only advisable at first light, with serious heat precautions. The Hajar mountains (Jebel Akhdar, Jebel Shams) are markedly cooler and the most comfortable summer escape.
Note: heat and humidity build through the month; hydration is critical, and midday outdoor exertion is genuinely risky. Plan an indoor-heavy itinerary.

Very hot and dry — around 39°C/28°C (102°F/82°F). Lightweight, loose, light-coloured clothing, a hat, and constant hydration. UV is extreme (11). Headscarf and modest cover-up for the Mosque.
