Qatar is poised to experience its first significant decline in temperatures on September 20, marking the onset of a gradual seasonal transition, as reported by Dr. Faisal Al Ansari, Executive Director of the Qatar Calendar House.

The year is divided into 28 star periods, with four periods falling under the Suhail phase. The Suhail period, which lasts 53 days, includes four main stars: Al Tarfah, Al Jabha, Al Zubrah, and Al Sarfah. Most of these periods last approximately 13 days, with Al Jabha extending to 14 days, speaking to Al Rayyan TV, Dr. Al Ansari explained.

Observations from the Qatar Calendar House indicate that the first noticeable temperature drop and climatic shift begin on September 20, roughly 26 days after the commencement of the referenced star periods.
