Climate summary for January in UAE

This Month is characterized by drop in temperatures where the weather is cool during daytime and cold during night in general, due to extension of ridge of high pressure system building over Siberia associated with a cold air mass that affects the country and the Arabian Peninsula in general.

  Additionally, during this month, the region is affected by a succession of low pressure systems that pass from West to East, and the country is affected by the extension of the red sea trough at times. Sometimes those pressure systems associated by upper air troughs lead to cloud developments over the country in some days of the month with rainfall.

   The country also experiences strong Northwesterly winds (Shamal) during this month, which cause blowing sand and dust over inland areas especially the exposed areas. These winds lead to rough sea with an increase wave height.
