Contrary to popular belief, Oman is arguably a year-round destination, with the two main seasons presenting their own distinctive advantages (and disadvantages). The winter season, which persists from November through April, is when the country sees the highest influx of tourists thanks to the pleasant and welcoming weather. As for the cons, Oman can get pretty expensive during this time of the year in response to the soaring demand.
When it comes to the summer, which goes from May through October, you can enjoy Oman without the buzzing of hordes of tourists and take advantage of unbelievably low prices but under the scorching hot sun. So it is up to the likings of the traveller inside of you to determine the best time to visit Oman.
