As a potential Super El Niño looms in 2026-27, Pakistan – already among the world’s most climate-vulnerable nations – faces heightened risks of erratic monsoons, severe heatwaves, water scarcity, and economic strain that could threaten food security and human livelihoods.

Pakistan stands at the precipice of another major climate challenge as meteorological experts warn of a developing Super El Niño – a potent phase of the El Niño-Southern Oscillation (ENSO) cycle that could rank among the strongest on record. With sea surface temperatures in the central and eastern Pacific projected to rise significantly, potentially exceeding 2°C above average, this event threatens to disrupt global weather patterns, amplifying extremes in an already warmer world due to climate change.

For Pakistan, ranked among the top climate-vulnerable countries, the implications extend far beyond weather forecasts. The phenomenon could suppress the southwest monsoon, intensify heatwaves, strain water resources, and trigger cascading effects on agriculture, energy, public health, and economic stability. Recent experiences with devastating floods (like 2010 and 2022) and prolonged droughts underscore the nation’s precarious position.

Understanding Super El Niño

El Niño occurs when unusually warm waters in the Pacific alter atmospheric circulation, leading to droughts in some regions and floods in others. A “Super” El Niño refers to exceptionally strong events, such as those in 1982-83, 1997-98, and 2015-16, which caused widespread agricultural losses, economic disruption, and humanitarian crises.

Forecasts from NOAA, the World Meteorological Organization (WMO), and Pakistan Meteorological Department (PMD) indicate a high probability – around 80 per cent or more – of El Niño developing in 2026 and strengthening into winter 2026-27, with a substantial chance of it becoming very strong. Climate change is amplifying these risks, as warmer baseline ocean and atmospheric temperatures can intensify extremes. Projections suggest 2027 could vie for the warmest year on record.

Implications for Pakistan’s Monsoon and Water Security

One of the primary concerns for Pakistan is the likely weakening and increased unpredictability of the 2026 southwest monsoon. PMD has forecasted below-normal rainfall across much of South Asia, including Pakistan, alongside above-normal temperatures. This could lower reservoir levels, reduce river flows, limit groundwater recharge, and exacerbate water scarcity in a country already nearing stress thresholds.

Agriculture, which employs a large portion of the population and contributes significantly to GDP, is highly vulnerable. Major crops like wheat, rice, cotton, sugarcane, and maize could suffer from reduced irrigation and prolonged dry spells. Livestock in arid regions such as Balochistan may face fodder shortages and higher mortality. Historical precedents, including droughts following the 1998 El Niño, highlight the potential for multi-year impacts.

While overall rainfall may decline, irregular patterns could still produce intense bursts leading to flash floods, urban flooding, and landslides, particularly in northern and mountainous areas like Khyber Pakhtunkhwa. The National Disaster Management Authority (NDMA) has already issued cautions.

Heatwaves, Health, and Human Security Risks

Rising temperatures compound these threats. Pakistan has endured increasingly severe heatwaves, with cities like Jacobabad and Sukkur frequently surpassing 45°C. A Super El Niño could push these higher, especially in southern regions, heightening heat stress in humid coastal areas like Karachi. Vulnerable groups – children, the elderly, outdoor workers, and those with pre-existing conditions – face elevated risks of heat-related illnesses and mortality.

Public health systems may strain under combined pressures of heat, potential disease outbreaks (such as dengue, favoured by erratic weather), and food insecurity. Broader human security concerns include displacement, livelihood losses, and social instability from rising food and energy prices.

Economic and Energy Sector Vulnerabilities

The economic toll could be substantial. Reduced agricultural output would drive up food prices, while damaged infrastructure from floods or droughts disrupts supply chains and productivity. Hydropower generation, a key part of Pakistan’s energy mix, could decline with lower reservoir levels, increasing reliance on costly imported fuels amid potential global market volatility.

Broader analyses suggest El Niño events can shave percentage points off GDP growth in affected regions through inflation, lower yields, and recovery costs. For Pakistan, already navigating economic challenges, this adds another layer of pressure on fiscal resources and development goals.

Global Context and Interconnected Risks

The Super El Niño is not isolated to Pakistan. Across Asia, it threatens food security through drought and heat impacts on rice and other staples, potentially fuelling inflation and social pressures. In other parts of the world, it may bring contrasting extremes – wetter conditions in some areas, severe dryness in others. The interaction with ongoing climate change and geopolitical factors (such as energy supply disruptions) heightens systemic risks.

Policy Recommendations and Preparedness

Experts emphasise proactive measures. Enhancing forecasting and early warning systems through PMD and NDMA is critical. Investments in water infrastructure – reservoirs, efficient irrigation (drip and sprinkler systems), rainwater harvesting, and canal modernization – can build resilience.

Agriculture needs a shift toward drought-resistant, heat-tolerant crop varieties, climate-smart practices, and insurance schemes. Urban heat action plans, including cooling centres and better drainage, alongside ecosystem restoration and renewable energy expansion, are vital. Initiatives like Recharge Pakistan exemplify nature-based solutions.

International cooperation on climate adaptation, technology transfer, and finance will be essential for a country bearing disproportionate impacts despite low historical emissions.

A Call for Urgent Action

The emerging Super El Niño serves as a stark reminder of Pakistan’s exposure to global climate dynamics. While uncertainties remain about the event’s exact intensity and localized effects, the science is clear: preparation now can mitigate losses and foster long-term resilience.

As temperatures rise and extremes multiply, transforming vulnerability into adaptive capacity is prudent, the country’s meteorological department says.
