Saudi Arabia: The Sudan seasonal depression deepens and the dust season is active on the southern coasts of the Kingdom.

Arab Weather - The latest weather analyses indicate that what is locally known as the "dust season" will be active across parts of the southwestern sector of the Kingdom in the coming days. This is due to northwesterly winds coming from Sudan, carrying varying amounts of dust and dirt, leading to a noticeable decrease in horizontal visibility in some areas.

What is the dust season?

"Dust Season" is a local term used by residents of the southwestern coasts of the Kingdom of Saudi Arabia, particularly in the regions of Al-Lith, Al-Qunfudhah, and the coasts of Jazan, to describe the active monsoon winds that cause seasonal dust waves, significantly affecting the atmosphere.

Scientific reasons for the dust season

The dust season is associated with the deepening of the Sudan Thermal Low, which pushes active southwesterly winds toward the Horn of Africa. These winds stir up dust in Sudan, which then drifts toward the southwestern highlands of the Kingdom, such as Jazan, Asir, and sometimes Al-Baha and Taif. This also coincides with active westerly winds on the Red Sea coast, causing additional local dust to be stirred up on coastal roads.

When does the dust season end?

The dust season typically occurs between late June and mid-August. Dust waves can significantly reduce horizontal visibility, potentially affecting patients with respiratory and eye conditions, especially during the daytime when the winds are active.

And God knows best.
