Explanations:Chennai, the capital city of Tamil Nadu, experiences a tropical wet and dry climate with distinct wet and dry seasons. The wettest month in Chennai is November, which is the peak of the North-East Monsoon season. The North-East Monsoon, also known as the Retreating Monsoon, typically starts in October and lasts until December, bringing significant rainfall to the region.
The monsoon season in Chennai is characterized by the movement of the monsoon winds from the Bay of Bengal towards the Indian subcontinent. These winds, laden with moisture, bring heavy rainfall to the coastal regions of Tamil Nadu, including Chennai. The North-East Monsoon is crucial for agriculture and water supply in the region, as it replenishes the water bodies and supports the cultivation of crops.
Understanding the climatic patterns of Chennai is essential for various purposes, including urban planning, water management, and agricultural activities. The wettest month, November, is a critical period for these activities due to the high rainfall. It is important to note that while October marks the beginning of the North-East Monsoon, the rainfall typically peaks in November, making it the wettest month.
Other months in the year, such as February and March, are part of the dry season in Chennai, characterized by low rainfall. The South-West Monsoon, which occurs earlier in the year, does not significantly impact Chennai's rainfall as it primarily affects the western and central parts of India. Therefore, the North-East Monsoon is the primary source of rainfall for Chennai, with November being the wettest month.
