Step 1: Define retreating monsoon.
The retreating monsoon season occurs during the months of September to November, when the monsoon winds start to withdraw from India.
Step 2: Weather conditions.
During this season, the weather conditions are characterized by:
- Decreasing rainfall across most parts of the country.
- Clear skies and lower humidity levels.
- Cooler temperatures in northern and central India, with some parts of the south continuing to experience rainfall.
Step 3: Changes in air pressure.
The air pressure begins to rise over the landmass as the monsoon winds retreat, causing drier conditions in many areas.
