Saudi Arabia | Will the first third of the season end without rain?

Arab Weather meteorologists are monitoring the latest numerical models and weather maps indicating that various regions of the Kingdom will continue to be affected by a high pressure system, which will maintain generally stable weather conditions, with limited chances of rain in some highlands of Jazan, Asir, and Al-Baha.

Does the first third of the season end without rain?

According to the latest analysis issued by Arab Weather, various regions of the Kingdom are expected to remain under the influence of the same prevailing weather system until the end of October. This portends that the first third of the Wasm season will pass without significant rainfall affecting the Kingdom.

Reasons for the delay of the Wasm season this year

• Delayed cold air masses and low-pressure systems: They usually arrive from the eastern Mediterranean to the Arabian Peninsula, and their delay leads to a delay in the rains associated with the season.
• Lower surface temperatures: The formation of cumulus clouds, which are responsible for the thunderstorms typical of the Wasm season, decreases.
• Jet stream activity: It enhances atmospheric stability and reduces atmospheric instability, reducing the chances of precipitation.
• The impact of western low pressure systems: The strength of the low pressure systems in the western Mediterranean strengthens the jet stream and reduces the chances of cold low pressure systems penetrating the Kingdom.

Arab Weather experts continue to monitor daily developments to determine any future signs of rainfall during the second third of the Wasm season, keeping in mind that weather fluctuations at this time of year can change rapidly due to climate change and seasonal weather patterns.
