A regional cold wave will affect eight Arab countries starting Sunday night/Monday morning and continuing until midweek.

Arab Weather - Computer simulation maps at the Arab Weather Center, specifically those related to air mass distribution, indicate that the eastern Mediterranean basin will be affected by an air mass colder than usual for this time of year, starting Sunday night/Monday morning, May 3, 2026. Its effects are expected to be noticeable through a significant drop in nighttime temperatures, which may necessitate the return to heating in some areas, particularly in high mountain regions. For this reason, the situation has been described as a relatively late cold wave, despite its rapid onset.

A regional cold wave will affect eight Arab countries starting Sunday night/Monday morning and continuing until midweek.

This air mass is expected to affect about 8 Arab countries during the period from Sunday night/Monday until the middle of the week, including Libya, Egypt and the Levant, in addition to the western parts of Iraq and the northwestern parts of Saudi Arabia.

As for temperatures, they are expected to drop significantly during the night in several major cities, where they may reach about 8 degrees Celsius in the capital Amman, about 13 degrees Celsius in the capital Tripoli, and about 11 degrees Celsius in Cairo, while they will be lower than that on the high mountain peaks, and may approach zero degrees Celsius on the high mountains in Lebanon, and reach about 5 degrees Celsius on the southern highlands in Jordan.

On Monday, the cooler-than-usual air mass will continue to affect the region, keeping daytime temperatures below average for this time of year and resulting in generally cool weather, particularly across the Levant. This weather pattern will also bring heavy rainfall to several areas of Syria and Lebanon, with a possibility of snow on the high mountain peaks of Lebanon.

Strong winds accompany the cold wave, causing sandstorms in desert areas and roads.

This air mass is also expected to be accompanied by active to strong winds at times, which may stir up dust and form sandstorms in desert areas, while causing sea disturbances and a significant increase in wave height in the Mediterranean Sea, especially off the Syrian and Lebanese coasts.

This comes at a time when the weather is supposed to be more moderate as we approach summer, which makes the impact of this cold air mass more apparent, especially during the night.

Accordingly, it is advisable to wear warm clothes, not to rush to lighten them, and to be aware of the large temperature differences expected during the first days of May, in addition to being aware of the active winds and dust storms in exposed areas.
