October heat is associated with which season?

Correct answer: Retreating monsoon

Direct answer: Option C, the retreating monsoon, is correct. In northern India, the southwest monsoon begins to withdraw around September and October. During this transition, the land may still be very warm, while the air contains considerable moisture. The combination of high temperature and humidity creates uncomfortable “October heat.” Rainfall may also occur in some regions during the withdrawal period, but the key exam association is retreating monsoon. Option A is wrong because the cold weather season has lower temperatures and is not the usual cause of October heat. Option B is less correct because October heat is not simply the main rainy season; it is specifically linked with the withdrawal or retreat of the monsoon. Option C is correct because it names the seasonal transition responsible for this condition. Option D is wrong because spring occurs later and does not explain this October phenomenon. Memory cue: October heat = hot land plus humid air during the retreating monsoon.
