The Sultanate’s varied geography results in a wide 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 hottest months are June through August. The summer monsoon just touches the southern coast of Dhofar during these months bringing regular light rain to Salalah and reducing the average daytime highs to 30°C.

The most pleasant months to visit Oman are mid October through March when daytime temperatures fall into the lower 30s and below.

Rainfall varies but in general remains sparse and irregular. In the south most of the year's rainfall occurs during the summer 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.
