The duration of monsoon in India extends for an average period of____
Explanation
The duration of the monsoon in India typically extends for an average period of 100 to 120 days. This period corresponds to the advancing monsoon season, which generally begins in early June and lasts through September [1]. The onset of the moisture-laden southwest monsoon winds usually occurs in the first week of June in coastal areas like Kerala and Karnataka, reaching the interior parts of the country by the first week of July [2]. During this season, India receives more than 75% of its annual rainfall [1]. While the withdrawal of the monsoon begins in northwestern India by early September, the core rainy season is defined by this 100–120 day window. This seasonal reversal of winds is a defining characteristic of India's subtropical monsoonic climate.
