Qatar marks the autumnal equinox on Wednesday, September 23, 2026, as summer comes to an end astronomically and autumn begins. According to the Qatar Meteorology Department, the autumnal equinox marks a seasonal transition as the Sun is positioned directly over the equator. This period also signals a gradual change in weather conditions, with temperatures beginning to moderate and local rain clouds expected to increase at time.

The autumnal equinox is also an important astronomical event because the hours of night and day are equal on this day. The Sun rises at an angle of 90 degrees and sets in the true west, marking the point at which the seasons begin to shift from summer towards autumn. As the new season begins, the changing temperatures and possible increase in local rain clouds mark a noticeable transition in Qatar’s weather pattern.
