Aseer: The annual appearance of Sirius, known locally in the Aseer Region as Alb, on July 16 marks the beginning of the traditional autumn season in the region's climatic and agricultural heritage. Long associated with summer rainfall, agriculture, and seasonal weather changes, the season has for generations served as a natural calendar that local communities rely on to organize their farming activities.
According to Saudi Press Agency, researcher Dr. Abdullah Al-Mousa stated that the arrival of the star is often accompanied by dust blowing from the Tihama lowlands, a phenomenon locally known as Ghusmat Alb. The period also frequently coincides with the deepening of the Indian seasonal low-pressure system over the southwestern highlands, creating favorable conditions for the formation of cumulonimbus clouds and summer rainfall.
Al-Mousa added that the season is also marked by several natural signs recorded in local folklore, including the emergence of certain insects and reptiles and the fledging of young crows from their nests.
