The warning issued by the World Meteorological Organisation this week should not be treated as just another weather bulletin from an international agency. For countries like Sri Lanka, the prospect of a moderate to strong El Niño event developing over the coming months is a reminder that climate shocks are no longer occasional disruptions. They are becoming a regular feature of life, affecting everything from agriculture and water security to public health and economic stability.
The WMO has forecast that El Niño conditions are likely to persist until at least November, with the possibility of above-average temperatures across much of the world. While there remains some uncertainty about the eventual strength of the phenomenon, the message from scientists is clear. Governments and communities should prepare now rather than react later.
Sri Lanka has experienced the effects of El Niño before. The weather pattern has often been associated with prolonged dry spells in some regions and intense rainfall in others. Such extremes are particularly challenging for a country whose economy, food security and rural livelihoods remain closely tied to weather conditions.
The timing of this warning is especially concerning. Sri Lanka is still recovering from years of economic hardship. Farmers continue to grapple with rising costs, uncertain market conditions and lingering concerns over access to agricultural inputs. A severe drought or erratic rainfall pattern could reduce crop yields, place additional pressure on food supplies and contribute to higher prices at a time when many households are already struggling to make ends meet.
Rice cultivation, vegetable farming and plantation crops all depend on relatively predictable weather patterns. When rainfall arrives too late, too early or in excessive amounts, entire harvests can be affected. The consequences are not limited to farmers. They are felt across the country through food inflation, reduced incomes and increased pressure on Government assistance programmes.
Water management will be another critical challenge. Sri Lanka relies heavily on reservoirs for irrigation, drinking water and hydropower generation. Extended dry periods could reduce water availability and affect electricity generation, while sudden heavy rains could overwhelm reservoirs and increase flood risks downstream. The country has witnessed both droughts and devastating floods in recent years. El Niño raises the possibility that such extremes could become even more pronounced.
Public health authorities must also remain vigilant. Higher temperatures increase the risk of heat-related illnesses, particularly among the elderly, outdoor workers and vulnerable communities. Warm and wet conditions can also create favourable environments for mosquito-borne diseases such as dengue, which already remains a serious public health concern in Sri Lanka. The country's healthcare system must be prepared for the possibility of increased demand during periods of extreme weather.
What makes this warning particularly significant is that it comes against the backdrop of a warming planet. Scientists point out that while climate change may not directly increase the frequency of El Niño events, it can intensify their impacts. In simple terms, an El Niño occurring in a warmer world can produce more severe consequences than one that occurred decades ago.
This reality demands a shift in thinking. Disaster preparedness can no longer be viewed as an emergency response function alone. It must become a central part of national planning. Ministries responsible for agriculture, irrigation, health, energy and disaster management should already be coordinating contingency measures. Local authorities should assess vulnerabilities and ensure that emergency plans are updated and ready for implementation.
At the same time, citizens have a role to play. Conserving water, supporting dengue prevention efforts and remaining attentive to weather advisories are practical steps that can help communities become more resilient. Awareness and preparation often make the difference between a manageable challenge and a costly crisis.
The warning from the United Nations should also reignite discussions about long-term climate resilience. Investments in water storage, climate-smart agriculture, renewable energy and stronger early warning systems are no longer optional luxuries. They are necessities for countries exposed to increasing climate volatility.
Sri Lanka cannot prevent El Niño from developing. Nor can it control global climate trends. What it can do is prepare intelligently and act decisively. The months ahead may test the country's resilience. The best response is not panic, but preparedness. If the warnings are heeded today, the hardships of tomorrow can be reduced. Ignoring them, however, would be a risk Sri Lanka can ill afford.
