Is Sri Lanka ready for an El Niño heat wave?

Sri Lankans are used to talking about floods and heavy rains. When rivers overflow or roads go underwater, the danger is clear and immediate. But there is another threat building quietly, one that does not make as much noise but affects just as many people. The heat is rising and, with the possible return of El Niño in the coming months, the question we must ask is simple. Is Sri Lanka ready?

Over the past few weeks, the signs have already been there. The afternoons feel longer and heavier. Nights are warmer, making it harder to sleep. Even simple daily tasks feel more tiring than before. For many, this is just seen as part of living in a tropical country. But this time, it may be more than that.

El Niño is a global weather pattern that often brings hotter and drier conditions to countries like Sri Lanka. If it strengthens around May, as some forecasts suggest, the country could experience prolonged heat and less rainfall. This is not just about discomfort. It has real effects on how people live and work.

Take a farmer in Anuradhapura as an example. He waits for the rains to prepare his paddy field. If the rains are delayed, the soil dries up. Seeds cannot be planted on time. Even if they are, the lack of water affects the harvest. Weeks of effort can be lost. When harvests fall, food supply drops. When supply drops, prices go up. What starts in a field ends up being felt at a market stall in Colombo.

Or consider a three wheeler driver in the city. He spends hours on the road under the sun. With rising heat, he becomes tired faster. Dehydration sets in. Headaches become common. But he cannot afford to stop working because his daily income depends on it. For him, the heat is not just uncomfortable. It directly affects his ability to earn.

The impact reaches homes as well. A mother trying to put her baby to sleep at night struggles because the room is too warm. An elderly person feels weak and dizzy during the day. A school child finds it hard to concentrate in a classroom with poor ventilation. These are everyday situations that many Sri Lankans can relate to.

Water is another growing concern. During hotter months, people naturally use more water. At the same time, if rains are reduced, reservoirs do not fill up as expected. This creates a gap between supply and demand. In some areas, this could mean water cuts. In others, it could mean long queues to collect water. We have seen this before during dry periods. It may return again.

Electricity demand also rises with the heat. More fans are switched on. Those who can afford it use air conditioners. Refrigerators work harder. All of this puts pressure on the national grid. Sri Lanka has already faced power shortages in the past. A sudden increase in demand during a heat wave could bring back those challenges. Despite all this, heat is not treated as a serious issue. There are warnings for floods and storms, but very little focus on extreme heat. Many people do not even realise when the body is overheating. Feeling dizzy, unusually tired or having a dry mouth are often ignored until it becomes worse.

So, is Sri Lanka ready for an El Niño impact? The honest answer is not quite.

Preparedness does not always require large investments. Sometimes, it starts with simple steps. Clear public messages about staying hydrated and avoiding direct sun during peak hours can help. Schools can adjust timings if classrooms become too hot. Workplaces, especially those involving outdoor labour, can allow short breaks to reduce heat exposure. Communities also have a role to play. Checking on elderly neighbours, ensuring children drink enough water and being mindful of how the heat affects others are small but important actions. At a broader level, Sri Lanka needs to start thinking long term. Cities are becoming more crowded and built up, often with fewer trees. Shade is disappearing. Green spaces are shrinking. These changes make urban areas even hotter. Planting trees and protecting existing greenery may seem like slow solutions, but they make a lasting difference.

Another important step is planning for water. Better management of reservoirs, reducing wastage and preparing for dry periods can ease the pressure when rains are low. These are not new ideas, but they need consistent attention.What makes heat different from other disasters is that it builds slowly. There is no single moment when it begins. But once it takes hold, it affects everything from health to income to daily comfort. The question is no longer whether the heat will come. It is whether we are willing to take it seriously.

Because in the end, the true impact of heat is not measured in degrees, but in how it quietly changes the way we live each day.
