El Nino Is Active Now in India, May Get Stronger This Monsoon: IMD
El Nino is active now in India, with the India Meteorological Department (IMD) and the Earth System Science Organisation (ESSO) confirming the phenomenon is already influencing weather patterns. The latest climate bulletin released by these agencies highlights that El Nino conditions are currently active over the equatorial Pacific Ocean and are expected to strengthen during the upcoming southwest monsoon season. This development has raised concerns among meteorologists and agricultural planners, as El Nino is known for its significant impact on monsoon dynamics and climate variability across the region.
The Role of El Nino in Climate Patterns
El Nino is a climatic phenomenon characterized by the warming of sea surface temperatures in the central and eastern equatorial Pacific, which disrupts normal weather patterns. This warming is linked to the weakening of trade winds, the oceanic and atmospheric currents that typically circulate warm water westward. As the trade winds weaken, the thermal energy redistributes, creating a feedback loop that sustains and intensifies El Nino conditions. The IMD's analysis indicates that these changes are already visible in India's current climate, with implications for the upcoming monsoon season.
El Nino is part of the El Niño-Southern Oscillation (ENSO) cycle, a natural climate pattern that alternates between warm (El Nino) and cool (La Nina) phases. The current phase, El Nino, is affecting atmospheric pressure systems and precipitation trends in India, leading to altered rainfall distribution. For instance, regions that typically receive heavy monsoon rains may experience drier conditions, while others could face unexpected downpours. The IMD emphasizes that these shifts are already observable and could have cascading effects on agriculture, water management, and power generation.
Potential Strengthening of El Nino During the Monsoon
According to the latest forecasts, El Nino is not only active but may grow stronger during the southwest monsoon season, which runs from June to September. This is a critical period for India, as the monsoon provides over 70% of the country’s annual rainfall. The IMD warns that the intensification of El Nino could lead to a more pronounced weakening of monsoon winds, resulting in delayed or reduced rainfall in key regions such as the Western Ghats and the Indo-Gangetic Plains. Such changes might exacerbate drought conditions in some areas while increasing the risk of flooding in others.
The current El Nino conditions have already influenced India’s weather in 2025, with anomalies in temperature and precipitation patterns. The Earth System Science Organisation (ESSO) reports that sea surface temperatures in the Pacific have risen by 0.8°C above average, a trend that could continue into the monsoon season. This warming affects the Walker Circulation, a large-scale air flow pattern in the tropics that drives monsoon rains. As the Walker Circulation weakens, the monsoon may become less predictable, posing challenges for farmers and urban planners who rely on seasonal forecasts.
Historically, El Nino events have been associated with below-average monsoon rainfall in India, often leading to water shortages and agricultural distress. The 2023-2024 El Nino, for example, contributed to a 15% reduction in rainfall across parts of the country. However, the 2025 event has shown different characteristics, with some regions experiencing early monsoon onset while others face prolonged dry spells. The IMD's latest bulletin suggests that the strength of El Nino will determine the extent of these disruptions, making it essential for stakeholders to monitor developments closely.
El Nino's influence extends beyond rainfall, impacting temperature extremes and agricultural productivity. During the monsoon season, the phenomenon can lead to higher-than-average temperatures in northern and central India, while southern regions might see a more moderate climate. This temperature variation affects crop cycles, with heat stress potentially damaging sensitive crops like rice and wheat. Additionally, the altered precipitation patterns may lead to uneven water distribution, complicating irrigation schedules and reservoir management.
As the El Nino phenomenon continues to evolve, its effects on India's climate are becoming more pronounced. The IMD is urging authorities to prepare for potential challenges, including water scarcity, reduced crop yields, and increased energy demand due to higher temperatures. The department has also highlighted the importance of early warning systems and adaptive strategies to mitigate the impact of El Nino on the country's socio-economic stability. With the monsoon season approaching, the active El Nino is likely to play a pivotal role in shaping India's climate outlook for the coming months.
