Oman enjoys high temperatures virtually year round; but the best time to go is between November and March when it’s slightly cooler.
The hottest months are between June and September, when temperatures can soar to 113°F (45°C) and more during the day when humidity levels are very high. Even the sea temperature touches on 104°F (40°C) during the summer months, and swimming pools at hotels are usually cooled.
Temperatures are only slightly more moderate the rest of the year, the coolest time being between December and March. There is very little rainfall in Oman, but when showers do fall it is mainly in the cooler months.
