The best time to visit Muscat is in the winter months between October - March. The temperatures are average with a minimum of 15 degrees and a maximum of 30 degrees. The weather during these months allows for tours around the city to the local market, beach and forts, etc without the extreme heat of the summer months (45 degrees +). It is best to avoid the extreme heat of the summer months with high humidity and extreme temperatures that could rise to 50 degrees.
