The climate of the UAE is sub-tropical to arid with little rainfall. The country experiences 2 seasons annually with warm winters and hot summers, although some say these months should really just be called hot and hotter. With such a small land area, the climate throughout the UAE is pretty similar and water temperatures vary from 20 degrees Celsius in winter to around 38 degrees Celsius in summer.
Season and Clothing
Summer: May to September
The summer months can be unbearable in the UAE with temperatures from the mid-30s up to 50 degrees Celsius and over 90 percent humidity. High summer is during July and August with consistent temps in the high 40s. The holy month of Ramadan also falls around this time, which is when Muslims fast from sunrise to sunset.Consider if you want to travel during this time as, while hotel rates are cheaper and there are less tourists about, non-Muslim visitors are also asked not to eat or drink in public places during the fasting period and opening hours tend to be erratic, which can severely curtail your holiday plans. On the plus side, rainfall is scarce but the sun is scorching.
Winter: October to April
Winter is the ideal time to visit the UAE with warm average daytime temperatures of around 24 degrees Celsius and cooler evenings, which can get down to 14 degrees Celsius. During October and November and March to May, daytime temps can still reach up to 35 degrees Celsius although the humidity is much lower than summer. This time of year is also high season and when the majority of major events are on in Dubai and Abu Dhabi so you’ll need to plan your travel and accommodation here well in advance. This is also the only time of year that rain occurs with short, heavy downpours that clear quickly. Swimwear is acceptable on the beach, but you'll need to dress modestly everywhere else, especially if you wish to visit mosques and other religious sites.
