The south-west monsoon starts retreating from Punjab plains by -

Correct option is C

The correct answer is (c) Mid-September. The south-west monsoon typically starts retreating from the Punjab plains by mid-September. This period marks the beginning of the monsoon withdrawal, starting from the northern parts of India and gradually moving southwards. The retreat of the monsoon signifies the end of the rainy season and the onset of the post-monsoon or autumn season in northern India. The timing of the monsoon retreat can vary slightly each year depending on climatic conditions.
Important Key Points:
· The south-west monsoon begins its retreat from the Punjab plains around mid-September.
· The retreating monsoon brings a decrease in rainfall and the beginning of drier conditions.
· This marks the transition from the monsoon season to the post-monsoon or autumn season.
· The withdrawal of the monsoon usually starts from the northwestern parts of India and progresses southwards.
· The timing of the monsoon retreat can be influenced by various climatic factors, including temperature and wind patterns.
· Understanding the monsoon cycle is crucial for agriculture, as it affects the timing of crop sowing and harvesting.
Knowledge Booster:
· Mid-July: Typically a period of peak monsoon activity in most parts of India, particularly in the northern and central regions.
· Mid-October: By this time, the monsoon has usually retreated from most parts of India, and the post-monsoon season is in effect.
· December: This is the winter season in India, well after the monsoon has retreated, and is characterized by cooler temperatures and dry conditions in most regions.
