Weather in Dubai
One of the United Arab Emirates in the Middle East, Dubai is located to the south-east of the Persian Gulf, on the Arabian Peninsula. The landscape both in and around its glamorous, cosmopolitan city, also called Dubai, consists of sandy desert, and the weather is hot and sunny all year round. The only variations in the climate are seasonal fluctuations in the degree of heat, some differences in humidity levels at certain times of the year, and, very occasionally, rain which falls as a few heavy showers, mainly in the winter months.
The most sizzling time of year in Dubai is between June and September, regarded as the summer months, when temperatures at midday hover at around 48°C (120°F), dropping somewhat a night, although with high humidity levels (around 90% on the coast in summer) conditions can still be uncomfortable.
The only unpredictable element in Dubai’s weather during the summer season is the incidence of a hot, dusty north-westerly wind called the Shamal, which whips up the desert into sandstorms if an area of low pressure develops over the Emirate.
There is no real autumn season as such in Dubai, but from October onwards temperatures gradually decrease until they reach their lowest points for the year between December and March. During the Dubai winter the mercury hovers between 22°C (72°F) and 30°C (86°F), and at night it can become positively chilly, particularly out in the desert where the temperature can drop as low as 5°C (41°F).
The winter months are also when most of the rainfall occurs, although with an annual average rainfall of only 150mm (5.9 ins) across the whole state, this does not impact too much on holiday activities. When it does rain, it comes in the form of short, heavy showers, with statistically February and March being the wettest months.
When is the best time to go to Dubai?
Dubai is an idyllic holiday destination all year round, with its long sunny days (up to 11 hours of sunshine a day in the mid-summer months of July and August) and predominantly rain-free climate. The height of summer, though, may be too hot for those accustomed to more temperate climates, particularly for desert excursions and beach going. The magnificent hotels, shopping malls and indoor attractions, however, are well air-conditioned, to the point that many travellers advise packing a cardigan even during the hottest season. Most visitors will find conditions more comfortable for outdoor pursuits during the winter, between December and March.
