Abu Dhabi has a sub-tropical, arid climate. Sunny blue skies and high temperatures can be expected most of the year. Rainfall is sporadic, falling mainly in winter (November to March) and averaging 12 cms per year in most of the emirate. Rain is more common in the 'Oasis City' of Al Ain, the emirate's second largest city, due to its proximity to the Hajar mountains.
Temperatures range from a low of around 13C (50F) on a winter's night, to a high of around 42C (118F) on a summer's day. The cooler months, November to April, are the most pleasant time to visit, when temperatures are around 24C (75F) during the day and 13C (56F) at night.
