The UAE lies between 22°50′ and 26° north latitude and between 51° and 56°25′ east longitude.
The largest emirate, Abu Dhabi, accounts for 87% of the UAE's total area (67,340 square kilometers). The smallest emirate, Ajman, encompasses only 259 square kilometers (see figure).
The climate of the U.A.E generally is hot and dry. The hottest months are July and August, when average maximum temperatures reach above 48 °C on the coastal plain. In the Al Hajar Mountains, temperatures are considerably lower, a result of increased altitude. Average minimum temperatures in January and February are between 10 and 14°C
