The Arab United Emirates (UAE) has a tropical desert climate which means hot and humid summers and comparatively cooler winters. For this reason, the best time to visit this destination weather-wise is December to March when sightseeing and swimming are the most comfortable. However, April, May, September and October (the spring and fall shoulder seasons) have pleasant weather, manageable crowds and reasonable hotel rates. If you’re looking for the best prices, then summer is the time to go - the city is practically free of tourists, but triple-digit temperatures and smothering humidity will make any time spent outdoors feel gruesome.
