Muscat Coast
The coastal strip around Muscat endures intense summer heat up to 38-40°C with high humidity from 60-90%, creating a stifling feel that prompts air-conditioned living. Winters bring comfortable 18-25°C days, perfect for beach outings. Rainfall is very low at 50-100 mm, mostly in brief winter showers.
