The India Meteorological Department predicts the southwest monsoon will arrive over the Andaman Sea and Bay of Bengal by this weekend [1, 2].
This weather shift is critical for the region's stability because nearly 45% of India’s net sown area lacks assured irrigation and relies entirely on rainfall [5].
A low-pressure area formed over the southwest Bay of Bengal on Monday [3]. This system is expected to bring rain to parts of Odisha over the next six days [3]. The intensifying system is bringing moisture that could trigger widespread rain across much of India [1, 4].
Despite the advance of the monsoon, the IMD provided a cautious outlook for the season. Monsoon rainfall is likely to be below normal at 92% of the long-period average, with an error margin of ±5% [2].
Recent weather patterns have shown volatility. Temperatures in New Delhi were above normal on April 28, 2024 [4]. While some reports indicate that thunderstorms and widespread rain may provide cooling relief, other forecasts suggest a fresh spell of rising temperatures is expected across north-west and central India despite the monsoon's progress [4].
The arrival of the monsoon marks the beginning of the primary agricultural cycle in India. The movement of the low-pressure system from the Bay of Bengal is the primary driver for this initial phase of the seasonal transition [1, 2].
“Nearly 45% of India’s net sown area lacks assured irrigation and depends entirely on rainfall”
The tension between the immediate arrival of rain-bearing systems and a predicted below-normal seasonal average creates a precarious situation for Indian agriculture. Because a significant portion of the country's farmland depends on the monsoon, any deficit in the long-period average could impact crop yields and food security, even if short-term low-pressure systems provide temporary relief from heatwaves.
