Winter has officially started in the UAE, with the onset marked by the winter solstice on December 21, 2025, according to astronomical calendars. The solstice signals the shortest day and longest night of the year in the Northern Hemisphere and is widely recognized as the formal start of the winter season.
In the weeks leading up to the solstice, residents across the country had already begun experiencing cooler conditions, with nighttime temperatures dropping significantly in several areas. Weather observers noted that late November brought some of the lowest readings so far this season, reinforcing the transition into winter conditions.
Aside from astronomical definitions, winter in the UAE is also traditionally associated with seasonal star cycles observed in the region, which typically align with cooler weather and calmer atmospheric conditions during December.
The winter season in the UAE generally runs until late March, bringing milder daytime temperatures, cooler evenings, and more favorable conditions for outdoor activities across the country.
