Dur Al Thamanin: What It Is and Its Impact on UAE Weather

As February begins, the UAE enters a traditional seasonal phase known as Dur Al Thamanin, or "the Eighty" (February 1–12). Rooted in regional weather lore, this period is marked by dynamic atmospheric changes that can influence temperature, wind, rainfall, and visibility across the country.

What is Dur Al Thamanin?

The name refers to roughly 80 days centered around early February, considered the most active part of the UAE's cool season. It is characterized by strong north-westerly Shamal winds and transitional weather patterns that sweep across the Arabian Peninsula.

Key Weather Features During This Period

• Strong Winds & Rough Seas: The most notable feature is persistent and powerful Shamal winds, strongest in the early mornings. These winds stir up dust, reduce visibility, and create rougher seas in the Arabian Gulf and Sea of Oman.
• Rain & Cloud Cover: The period often coincides with low-pressure systems from the Mediterranean, bringing increased cloud cover and occasional scattered showers. While heavy rain is rare, historical extremes exist (e.g., 317 mm in 1988).
• Temperature Trends: Average February temperatures hover around 20.1°C, but variability is high. Strong winds can make it feel cooler, especially in the mornings and evenings. Record highs near 39.8°C and lows of -5.7°C on Jebel Jais highlight the range.
• Fog & Humidity: February sees higher humidity (avg. 83%), leading to morning fog or mist, particularly in coastal and inland areas. In 2021, February recorded 18 days of dense fog.

Will It Bring Noticeably Cooler Weather?

Dur Al Thamanin can bring cooler, more unsettled weather, but it's not a guarantee of a dramatic temperature drop. Instead, expect increased variability: stronger winds, possible rain, cloudier skies, and cooler nights. The winds often make it feel cooler outdoors, even if daytime temperatures align with seasonal norms.

What to Expect in the Coming Days

• Gusty winds and rougher sea conditions.
• Possible rain showers and increased cloud cover.
• Morning fog or mist due to higher humidity.
• Temperatures near seasonal averages, with fluctuations.

Drivers should be alert for reduced visibility from fog and dust. Those planning outdoor activities should prepare for changeable conditions. While not a sure sign of a cold snap, Dur Al Thamanin is a recognized marker of winter's persistence and active weather in the UAE, offering a distinct and often dynamic start to February.
