A potential eastern wave could affect several countries in the Arabian Peninsula at the end of June. What is an eastern wave?

Arab Weather - The latest outputs from global numerical models indicate that parts of the Sultanate of Oman and the United Arab Emirates may be affected by an extension of a humid easterly wave coming from the Arabian Sea during the final days of June 2025. This could contribute to stimulating the formation of cumulus clouds and rainfall in some areas, particularly mountainous ones.

What is the eastern wave?

The East Wave is defined as an area of low pressure moving westward from the Indian subcontinent (India and Pakistan) toward the Arabian Sea. These waves are characterized by being laden with large amounts of tropical moisture. As they advance toward the eastern coasts of the Arabian Peninsula, specifically the Sultanate of Oman and the UAE, they interact with mountainous terrain such as the Al Hajar Mountains, leading to the formation of cumulus clouds and seasonal rainfall, known locally as "Rawaih" (rain). These waves are considered one of the primary drivers of weather activity in the Arabian Sea during the pre- and peak periods of the summer monsoon.

Indicators are still far away and subject to change.

Despite these preliminary indicators, the timeframe remains relatively distant, meaning significant changes are likely in future updates. The Arab Weather Center confirms that the weather forecast team is closely monitoring these indicators and will issue periodic updates should weather conditions stabilize or change over the coming days.

And God knows best.
