The varied geography of Oman has given it a diverse variety of climatic conditions. Although lying in the tropics, the Sultanate is subject to seasonal changes like the more temperate regions of the world.
The winter is cool and pleasant in Oman, but summer months are hot and humid specially. The interior remains hot and dry, except for the mountains where temperatures can drop drastically at night.
The hottest months are June through August but on the southern coast of Dhofar the monsoons bring light but persistent rain, resulting in a cool and misty summer. Rainfall varies but in general remains sparse and irregular. In the south, most of the year's rainfall occurs during the monsoon months. In the north, the opposite occurs.
Here most rain comes from occasional winter storms which descend out of the eastern Mediterranean during the months of January through March, depositing an annual average of 10 cm of rain on the capital area.
