Dubai Weather

 

The city of Dubai is situated on a coastal strip bordered by desert and gets very hot. It is dry on the hottest days and humid during the cooler days in the summer. Cooler, more pleasant weather lasts from the end of September to beginning of May (although note that pleasant is relative, with daily temperatures from October to January and March to May still being 20°C-25°C (68°F-77°F), but be prepared for cold night temperatures. In winter the temperature at night is usually from 10°C-16°C (50°F-60°F). From May to September, the sun is intense and temperatures can touch 45°C (113°F) in the city and even higher in the desert. The heat, coupled with a humidity of 60%-70% near the coast, effectively precludes most activity outdoors for the daylight hours during summer.

December to April generally produces the highest precipitation, which at 10 cm (5 in), still is little. Some years yield no more than a few minutes of shower in Dubai. November 2006 brought record rains up to 50 cm (25 in) of rain, with temperatures at record lows.

Weather Chart

The weather chart during much of the year shows a ridge of high pressure extending southwards into central Saudi Arabia with lower pressure over the eastern Gulf. Prevailing light to moderate north-westerly winds, known by their Arabic name shamal, meaning \'north\', are associated with mid-latitude disturbances. Along the western coastal plain, sea breezes tend to dominate with light south-south-easterlies at night being replaced by moderate north-westerlies during daytime. This pattern changes on the east coast where the proximity of the mountains results in gusty and less predictable wind shifts.

A good strong blast of northerly shamal is usually preceded in the UAE by strong southerly winds, raising desert sands and reducing visibility. The shift to northerly winds may be quite sudden and can be accompanied by rain, thunder storms, or dust-storms. At sea, conditions can become quite difficult for small boats with force seven winds whipping up twelve foot high waves. In summer, weather charts usually indicate a broad area of low pressure, extending from the western Sahara, across the Arabian peninsula and across Asia, to China. Local pressure variations in the Gulf combine with this to create weather conditions in the UAE. Steady north-westerlies, predominating in the central and northern regions of the Gulf, do not generally extend as far south as the UAE. When they do so, sea conditions around Abu Dhabi become quite rough, while the rest of UAE\'s coastal waters experience only slight swells.

The UAE is the first country in the Middle East to introduce the Satellite Delivered Information System technology (SADIS), a weather forecasting technology which covers the globe, with the exception of Polar Zones. According to the National Meteorological Authority (NMA) which is affiliated to the Ministry of Communications, the system supplies data on temperature, humidity, volcanoes and wind directions. It also enables the UAE to receive the latest forecasts for centers all over the world through direct contact with the world center in London. The NMA has qualified forecasters to operate the system, and is currently training more forecasters to operate it.

Temperatures

The summer months, from June to September, are too hot for comfort. Mid-day temperatures range from 35°C to 42°C and occasionally top 49°C at the height of summer. During this period there is a sharp drop in night time temperatures, with these falling to roughly half the midday readings, i.e. 20°C to 28°C, and providing a welcome respite from the searing heat of the day. Gulf waters exert a modifying influence on coastal zones, which experience less dramatic diurnal fluctuations in temperature, and higher humidities than inland regions. Although the evenings are not so cool, coastal towns do have the advantage of pleasantly refreshing sea-breezes. Mountainous regions are also cooler and less humid. From December to March, the climate is considerably more equable with midday temperatures ranging from 25 to 35°C and falling to as low as 9°C at night.

 

Wind

Arabic interest in the weather and in the different types of winds blowing across the desert stems from the Bedouin tribes, for whom changes in weather could mean the difference between life and death. For them, each wind had its own characteristics and was known by a different name; thus, the main period of storms was Al-Barih al-owd, while the minor storm period was called Al-Barih al-sagheer. The first major Shamal occurring around May 25th is the Al-Haffar, or the driller since it drills huge depressions in the desert dunes. The second, arriving in early June, coincides with the dawn star, Thorayya (Pleiades) and is therefore named Barih Thorayya.

During this one, which is somewhat more violent than the others, fishermen tend to remain in port, not just because of the wind\'s strength, but because ancient folklore tells them that this wind devours ships! Near the end of June, the last shamal arrives, known as the Al-Dabaran. It is a violent wind, continuing for several days. Local residents keep doors and windows firmly barred in a battle against the all-penetrating fine dust driven by these shamal winds into every conceivable nook and cranny.
