The southwest monsoon has officially arrived in Kerala, marking the beginning of India's most closely watched weather season. The India Meteorological Department (IMD) confirmed the onset a day earlier than previously forecast, following several days of intense pre-monsoon rainfall across the state. Heavy rain has already disrupted normal life, with all 14 districts under weather alerts and reports of waterlogging, rising river levels and landslide threats emerging from several regions.
Orange alerts have been issued for Alappuzha, Kottayam and Ernakulam districts, while the remaining districts are under yellow alert. Relief camps have been opened in vulnerable areas, and fishermen have been advised to stay away from the sea as rough weather conditions continue.
The monsoon remains one of the most important drivers of the Indian economy. The four-month rainy season supplies nearly 70 percent of the country's annual rainfall and supports agriculture, which continues to provide livelihoods for millions of Indians. Nearly half of India's farmland depends directly on monsoon rains, making the season crucial for crop production, rural incomes and food prices.
The arrival of the monsoon is also closely tracked by financial markets. A healthy and well-distributed monsoon generally boosts rural spending, benefiting sectors such as fast-moving consumer goods (FMCG), tractors, two-wheelers, fertilisers, agrochemicals and rural-focused banks. Strong farm output can help contain food inflation, creating room for lower interest rates and supporting broader economic growth.
This year, however, economists and investors are watching weather developments particularly closely. The IMD has projected below-normal rainfall for the 2026 monsoon season, with forecasts ranging around 90 percent of the long-period average because of developing El Niño conditions. Analysts warn that weak or uneven rainfall could affect kharif crops such as rice, pulses, oilseeds and maize, potentially pushing up food prices and dampening rural demand.
Even so, the link between monsoon performance and India's overall economic growth has weakened over the years as the economy has become more diversified. Experts note that while agriculture remains highly dependent on rainfall, services and manufacturing now contribute a much larger share of national output than in previous decades.
For now, the focus remains on the progress of the rains. A timely and well-spread monsoon could provide a significant boost to rural India and support market sentiment, while prolonged weather disruptions or a rainfall deficit could reignite concerns over inflation and growth in the months ahead.
