The timing of monsoon withdrawal can vary significantly from year to year. While it generally occurs between mid-September and mid-October, factors such as La Niña or El Niño conditions can influence its pace. For instance, during La Niña years, the retreat may be delayed. In 2019, the withdrawal commenced on October 9 and concluded on October 16, while in 2020 and 2021, it was delayed until late October. This variability makes forecasting the exact timing of withdrawal challenging.
