Packing for Muscat in August means dressing for 36°C days and 28°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 36°C daytime heat. Evening temperatures settle at 28°C, a modest 8°C drop that a light cardigan or denim jacket covers. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Loose-weave linen and moisture-wicking fabrics are the practical choice in Muscat's heat and humidity. Many shopping centres run air conditioning at near-arctic levels, so a thin layer in your bag prevents discomfort indoors.

Why is Muscat warm in August?
