The United Arab Emirates are among the hottest countries in the world.
The average summer temperature (June-July-August-September) in Dubai or Abu Dhabi is around 42°C! Added to this is the very high humidity that makes the heat even less bearable.
Winter is cooler but short in duration (January - February). The daytime temperature in Dubai is around 25°C, and at night it drops to around 14°C. It is colder in the desert (about 5°C at night).
Rainfall in Dubai occurs mainly in the winter period from December to March.
The best time to travel to the United Arab Emirates is from November to April, when temperatures range between 25 and 35°C. In October and May, temperatures can reach 40°C.
