What's the temperature in Oman? Is the coastal temperature wet or dry? How long is it hot?

Oman is basically dry and hot all year round, and there may be 1 month in winter to calculate the dry temperature (neither cold nor hot).

However, if there is a cyclone attack in the Indian Ocean (the frequency is about 1/5 of the typhoon attack in China, and there is a big one every five years on average, mostly in10 ~1), it will turn into short-term hot and humid weather. If this happens, it will only last for 1~2 days.
