The Department of Meteorology has cautioned that the climate phenomenon known as El Niño is likely to develop in the coming months, bringing with it reduced rainfall and the possibility of drought conditions, particularly during July and August. More concerning is the warning that its effects could persist until February 2027, with a significant chance the phenomenon may strengthen towards the end of the year.
For a country that remains heavily dependent on rainfall for agriculture, drinking water, hydropower generation, and livelihoods, this is not a forecast that can be treated lightly.
Sri Lanka is no stranger to the effects of El Niño. History has shown that the phenomenon can dramatically alter weather patterns, leading to prolonged dry spells, water shortages, crop losses, and heightened pressure on essential services. While weather forecasts are never absolute certainties, waiting until reservoirs begin to shrink or crops begin to fail would be a costly mistake.
Department of Meteorology Acting Director General, Ajith Wijemanna has rightly pointed out that preparations must extend beyond monitoring weather patterns. The health sector, energy sector, irrigation systems, agriculture, and water resource management all need to be ready for what may lie ahead.
Agriculture should be at the forefront of these preparations. Thousands of Sri Lankan families depend directly on farming, while millions rely on stable agricultural production for food security. Reduced rainfall during critical cultivation periods could affect paddy production and other crops, leading to lower yields and higher food prices. Farmers need timely guidance on water management, drought-resistant crop varieties, and cultivation planning. Agricultural authorities must work closely with farming communities now, not after the first signs of drought emerge.
Water management presents an equally urgent challenge. Every year, Sri Lanka experiences the familiar cycle of floods in some regions and water scarcity in others. Yet despite repeated warnings from experts, long-term water conservation measures often receive insufficient attention. If rainfall decreases significantly, the country will need to ensure that reservoirs, tanks, and irrigation networks are managed efficiently. Leakages in water distribution systems must be addressed, while public awareness campaigns should encourage responsible water use.
The energy sector also faces considerable risks. Hydropower continues to play an important role in Sri Lanka’s electricity generation mix. Lower water levels in reservoirs could reduce hydroelectric output and increase reliance on thermal power generation. This not only raises costs but can also place additional pressure on foreign exchange expenditure through fuel imports. Energy planners should therefore treat the El Niño warning as an opportunity to strengthen contingency plans and improve energy efficiency measures before shortages become a concern.
Public health considerations must not be overlooked either. Drought conditions can affect access to clean drinking water, increase the risk of waterborne diseases, and create challenges for vulnerable communities. Heat-related illnesses may also become more common if temperatures rise alongside reduced rainfall. Health authorities must be prepared to respond to these potential impacts, particularly in rural and drought-prone areas.
Perhaps the most important lesson is that climate-related challenges can no longer be viewed as occasional disruptions. They are becoming recurring realities. Around the world, countries are grappling with increasingly unpredictable weather patterns driven by climate variability and climate change. Sri Lanka is not immune to these trends. The country has experienced devastating floods, landslides, droughts, and extreme weather events within relatively short periods of time.
This makes preparedness not merely a seasonal responsibility but a national necessity. Effective responses require coordination between Government agencies, local authorities, researchers, farmers, businesses, and the public. Information sharing must be timely, decisions must be evidence-based, and planning must look beyond immediate political cycles.
The warning issued by the Meteorology Department provides something that is often unavailable during natural disasters: time. Time to prepare. Time to conserve resources. Time to strengthen systems. Time to minimise damage.
Whether that opportunity is utilised effectively will determine how successfully Sri Lanka navigates the months ahead. The arrival of El Niño may not be within our control. Our response to it certainly is.
