Southwest Monsoon

The Southwest Monsoon is India’s main rainy season and one of the most important weather systems affecting the country’s economy, agriculture and water security. Arriving usually in early June over Kerala, the monsoon spreads across most parts of India by mid-July and continues until September.

The monsoon develops because land areas over northern and central India heat up faster than the surrounding oceans during summer, creating low pressure over the subcontinent. Moisture-laden winds from the Indian Ocean then move towards the land, bringing widespread rainfall. These winds, known as southwesterlies, split into two branches — the Arabian Sea branch and the Bay of Bengal branch.

The Arabian Sea branch brings rain to the western coast and central India, while the Bay of Bengal branch moves towards eastern and northeastern India before spreading into the northern plains. Mountain ranges such as the Western Ghats and the Himalayas force the moist winds to rise, cool and produce rainfall.

Nearly 75 per cent of India’s annual rainfall comes during the Southwest Monsoon season, making it crucial for farming, hydropower, rivers, groundwater and drinking water supplies. Around 64 per cent of Indians depend on agriculture, much of which relies heavily on monsoon rains.

However, the monsoon is highly unpredictable. Delayed arrival, uneven rainfall, floods, droughts and long dry spells can severely affect crops, rural incomes and overall economic growth.

Meanwhile, the BJP is putting out videos showing how stubble burning is happening in Punjab.
