Does it rain in Dubai?

Rainfall in Dubai is infrequent and does not last for a long period. It mostly rains during the winter period between November and March in the form of short downpours and an occasional thunderstorm. On average, rain falls only 25 days a year.

Is this because the climate is hot?

The UAE is located in a dust hotspot that contributes to the arid climate. There is little to no rainfall, due to frontal systems from the west and northwest, which yields few inches of rainfall per year. This lack of rainfall has scientists and the government worried about water security in the future.

So you mean this goes with the whole UAE?

Yes because of the countries near Dubai.
