Winter has officially commenced in the United Arab Emirates, bringing with it a season of crisp air, comfortable days, and varied weather patterns across its diverse landscapes. The National Centre of Meteorology (NCM) confirmed that the winter season began on December 22, setting the stage for a period characterized by cold nights, generally mild daytime temperatures, and the possibility of occasional rainfall.
What Drives the UAE's Winter Weather Patterns?
The seasonal shift is primarily governed by the influence of the Siberian high-pressure system. This system channels cold air masses toward the Arabian Peninsula through northwesterly and sometimes northeasterly winds. The result is a significant dip in temperatures, most pronounced during the night and early morning hours. In some interior and mountainous regions, temperatures can plummet to below 0°C.
Complementing this, the UAE's winter is also shaped by low-pressure systems originating from the Red Sea, the Mediterranean, and occasionally from the east. These systems are responsible for increasing cloud cover and bringing precipitation to the country. Furthermore, calm and humid conditions in the early mornings often lead to the formation of fog, a common sight during this season.
A Tale of Three Terrains: Regional Weather Variations
The UAE's unique geography ensures that winter is experienced differently from region to region.
Desert Areas: Vast desert expanses witness cool to cold nights and early mornings, while days remain pleasantly mild, perfect for outdoor exploration.
Mountainous Regions: Highlands like Jebel Jais maintain a cool climate for most of the season. The coldest temperature recorded so far this winter was a chilly 3.5°C at Jebel Jais on December 20.
Coastal Zones: Residents and visitors along the coast enjoy moderate temperatures. The Arabian Sea remains calm with wave heights typically between 1 to 2 feet, creating ideal conditions for various marine activities and water sports.
Authorities have advised caution as occasional heavy rainfall may lead to runoff in valleys and wadis, posing potential risks.
Recent Events and the Seasonal Outlook
Even before the official start of winter, the UAE experienced a preview of its dynamic weather. Between December 18 and 19, strong winds brought torrential rain, flooding, and even hail to some areas. The severity of the conditions was evident as Dubai Police received over 39,000 emergency calls during the storms. Residents and tourists were alerted via emergency SMS messages to stay vigilant and avoid hazardous areas.
Looking ahead at the broader winter season, average conditions for the UAE are expected to include maximum temperatures ranging from 24°C to 27°C and minimums between 14°C and 16°C. Humidity levels will hover around 55% to 64%, with light to moderate wind speeds of approximately 11 to 13 km/h.
This combination of comfortable humidity, manageable winds, and pleasant temperatures makes the UAE winter the perfect time for a host of outdoor activities. From camping under the stars in the desert and hiking in the rugged mountains to enjoying beachside barbecues and exploring the nation's cultural sites, the season offers something for everyone seeking adventure and relaxation in a temperate climate.
