Oman is a desert oasis, thus the climate is typically hot and humid. The weather conditions can have a range throughout the year from extremely hot to a bit cooler than many may expect for the Middle East. It generally has two seasons consisting of summer and winter.

The best time to visit Oman is between October through March due to cooler temperatures in the winter months. It is the perfect time to visit and enjoy a host of activities outdoors like hiking, swimming, and festivals in the winter season. In the summer temperatures can be pretty high, thus making it difficult for visitors to enjoy outdoor activities. There is little to no rainfall, hence not allowing for relief or cooldowns much during the summer months.
