The emirates are a hot part of the world but aren't always sweltering. The summer reaches up to 45 °C. It can be much colder, but only as low as around 10 °C in the winter, depending on the part of the city you live in.   Dubai tends to be around 15 °C as a minimum year-round and can edge close to 50 °C, which is incredibly sticky. Still, just about every building has air conditioning - including the bus stops if you're using public transport.   The beaches are also a great place to visit in the heat, with the water an excellent way to cool off and enjoy a bit of a breeze.
