Dubai residents should prepare for the chilliest stretch of the winter season. Temperatures across the city and the wider UAE are expected to drop further between January 10 and January 22, with meteorology and astronomy experts pointing to one traditional culprit: Dur Al Sittin.
What is Dur Al Sittin?
Dur Al Sittin is a well-recognised seasonal period in the UAE's weather calendar. Locals know it as the time when winter temperatures reach their lowest levels — particularly during early mornings and after sunset. Crisp air, cooler winds, and sharp overnight temperature drops are all hallmarks of this phase. The name itself is rooted in the region's ancient astronomical traditions and has long been used to mark the heart of the Arabian winter.
Dubai Already Had a Preview
The cold did not arrive without warning. Just weeks before this forecast, parts of Dubai recorded temperatures as low as 13°C following rainfall that swept across the UAE. That weather system brought cooler air into the region, giving residents an early taste of what January's full cold spell could feel like.
Experts say the upcoming Dur Al Sittin period is expected to feel noticeably colder — especially in the early morning hours before sunrise.
How Cold Will It Get in the UAE?
While daytime temperatures will remain relatively pleasant, the sharpest change will be felt overnight and before dawn. Residents can expect:
- Early-morning temperatures in desert and inland areas dropping to around 5°C or lower - Colder winds during nighttime and early hours - Possible frost in some inland regions - Mild afternoons followed by quickly chilling evenings
Coastal areas including Dubai city itself will stay milder than the interior, but the difference between a warm afternoon and a cold pre-dawn will be striking.
When Is the Coldest Period?
The coldest stretch of the UAE winter is forecast between January 10 and January 22, making it the most significant cold spell of the season. Plan outdoor activities for midday, when temperatures peak, and layer up well before heading out in the evening.
Making the Most of Dubai's Winter Chill
Cooler weather is also an opportunity. Cosy cafés, long leisurely lunches, and outdoor walks during daylight hours are all at their most enjoyable during this window. Parks, beaches, and the desert all feel different — and often better — when the air is sharp and clear rather than hazy and humid.
Tip: Keep a light jacket or jumper handy at all times. Dubai's coldest days have officially arrived.
