When will the Siberian high begin to affect Saudi Arabia?

The Siberian High is the largest high-pressure system in the Northern Hemisphere and is responsible for the harsh , dry cold waves that hit Europe and Asia in winter. As it extends southward into southwest Asia, it directly affects the northern and eastern regions of Saudi Arabia , causing a significant drop in temperatures during the winter months.

When will the Siberian High begin to affect Saudi Arabia?

• The Siberian High typically begins its influence in late November, with cold air arriving from the north and east into Saudi Arabia.
• The peak of cold weather and frost waves occurs during December and January, especially in the regions of Qassim, Hail, the Northern Borders, and Riyadh.
• Its influence gradually begins to recede in February, with the entry of westerly winds.

The impact of the Siberian High on the weather in Saudi Arabia

• The Siberian High is pushing cold, dry winds towards Saudi Arabia, making it feel colder, especially at night.
• It causes widespread frost waves in the interior regions, sometimes affecting agricultural activity and daily life.

Its effect on atmospheric instability

• In some years, especially when El Niño prevails, the tropical current may become active over the Arabian Peninsula, pushing warm, humid air from the Arabian Sea into the upper atmosphere.
• If this coincides with the extension of the Siberian High , significant temperature differences are formed, leading to atmospheric instability , such as sudden thunderstorms or local storms in some areas of the Kingdom.

Note: The Siberian High is not just ordinary cold weather. It is a massive weather system affecting the entire Northern Hemisphere, and monitoring it is important for all those interested in weather and climate.
