Abu Dhabi has a desert climate; the summers are very hot with temperatures in the 40s, and humidity can reach 100%, especially during the evenings and night times. Winters are cooler and drier (like a European summer with daytime temperatures in the 20’s) with occasional heavy downpours in January, February and March. Indeed, the evening temperatures can fall as low as 14-15 degrees centigrade.
Average annual rainfall is 112mm. The prevailing wind is from the sea and windstorms that whip up the sand, known as ‘shamals’, are a feature of the climate. These may occur 5 or 6 times a year, mostly during the summer, and can occasionally last 36 hours. The coast sometimes has thick early morning fog in the spring and autumn.
