Although summer is already well underway, several traditional seasonal stages still remain before autumn officially begins in Saudi Arabia. These periods have long been recognized in local weather traditions and are associated with changes in temperature, agriculture and daily life across the Kingdom.
From July 17 to August 10, Saudi Arabia enters Jamrat Al-Qayz, traditionally regarded as the hottest part of the summer. Many regions experience some of the year’s highest temperatures during this period.
The intense heat is especially noticeable in inland areas, including Riyadh and the Eastern Province. Residents are generally advised to avoid prolonged outdoor activities during the hottest hours of the day and stay well hydrated.
The next stage, from August 11 to August 23, is known as Tabbakh Al-Tamr, or “the date-cooking season.” It is traditionally associated with the intense heat that accelerates the ripening of dates.
This period is particularly important for date farmers, as many varieties of dates reach maturity and become ready for harvest.
On August 24, the Suhail (Canopus) star rises in the sky, marking a well-known seasonal milestone in the Arabian Peninsula.
Although hot weather usually continues, the appearance of Suhail traditionally signals the gradual easing of extreme summer heat. Cooler nights begin to develop in many parts of the Kingdom over the following weeks.
The Autumnal Equinox, which falls on September 22 or 23, marks the astronomical beginning of autumn in the Northern Hemisphere.
On this day, daylight and nighttime are nearly equal in length. While temperatures vary across Saudi Arabia, the equinox marks the official transition into autumn, with conditions gradually becoming more moderate in the weeks ahead.
