Escalating drought risk is potential bad news for rural communities, power consumers.

The National Oceanic and Atmospheric Administration (NOAA) and the Climate Prediction Center (CPC) have confirmed that ENSO-neutral conditions are currently present in the equatorial Pacific Ocean. However, technical indicators suggest a rapid transition, with a 61% probability of El Niño emerging between May and July 2026. For international investors and executives operating in Colombia, this shift indicates a looming period of increased operational costs, specifically within the energy and agricultural sectors.

The El Niño Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean. During El Niño, trade winds weaken, allowing warm water to move toward the west coast of South America. Conversely, La Niña is characterized by stronger trade winds and cooler ocean temperatures. These fluctuations disrupt global atmospheric circulation, altering rainfall and temperature patterns across the planet.

In Colombia, the effects of these phenomena are distinct and significant. El Niño typically results in a sharp decrease in precipitation and a rise in average temperatures. Because Colombia relies on hydroelectricity for more than 60% of its total power generation, extended dry periods lead to lower reservoir levels. This forces the grid to rely on more expensive thermal generation fueled by natural gas and coal, which historically drives up spot market electricity prices for industrial and residential consumers.

“There is a 25% probability that the index reaches or exceeds +2.0°C during the Northern Hemisphere winter,” according to the National Oceanic and Atmospheric Administration.

The current technical diagnostic from NOAA shows that while the sea surface temperature index in the Niño-3.4 region was recently -0.2°C, the easternmost indices have already moved into positive territory. Furthermore, the equatorial subsurface temperature index has increased for five consecutive months. This accumulation of ocean heat is a primary driver behind the high probability of El Niño persistence through the end of 2026. Some models, including those from the European Centre for Medium-Range Weather Forecasts (ECMWF), suggest a 25% chance of a “strong” or “very strong” event, where temperatures exceed the 2.0°C anomaly threshold.

The Ministerio de Minas y Energía and the Comisión de Regulación de Energía y Gas (CREG) are monitoring these developments closely. A strong El Niño would place additional stress on a natural gas system already facing structural supply constraints. Reduced hydroelectric output coupled with a potential deficit in gas supply could lead to significant energy price volatility. In past events, such as the 2015-2016 cycle, these conditions resulted in substantial financial pressure on the national utility system and necessitated emergency conservation measures.

Agricultural productivity is equally at risk. The Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM) has identified the Caribbean and Andean regions—including departments such as La Guajira, Magdalena, and Antioquia—as highly vulnerable. During El Niño, these areas face increased risks of forest fires, water scarcity, and crop failure. For agribusinesses and exporters, this translates to disrupted planting cycles and higher production costs for staples like corn, potatoes, and vegetables, which can fuel domestic food inflation.

Conversely, when La Niña is in effect, Colombia faces the opposite extreme. The cooling of the Pacific leads to excessive rainfall, which can cause devastating landslides and flooding in mountainous terrain. While La Niña can replenish reservoirs, it often damages infrastructure and logistics networks, complicating the transport of goods to port. The current transition out of a La Niña phase provides a brief window of ENSO-neutral stability, which the CPC estimates has an 80% chance of lasting through June 2026.

For the international business community, the significance of these weather cycles extends to macro-economic stability. Persistent dry weather can impact GDP growth by raising the cost of basic services and reducing agricultural output. Strategic planning for 2026 and 2027 must account for these climatic variables. Meteorologists at Colorado State University note that El Niño also tends to reduce hurricane activity in the Atlantic, which may provide some relief for coastal logistics, but the primary threat remains the inland hydrological deficit.

As the Ministerio de Ambiente y Desarrollo Sostenible activates preventive mechanisms, companies are encouraged to review their energy procurement strategies and water management protocols. The next comprehensive diagnostic update from NOAA is scheduled for May 14, 2026, which will provide further clarity on the intensity of the projected warming trend. Understanding the mechanics of the ENSO cycle is no longer a matter of environmental interest but a necessity for risk mitigation in the Colombian market.

Ecopetrol’s board has approved a temporary leave for Ricardo Roa, keeping him out of office until Colombia’s presidential elections wrap up at the end of June 2026

Ecopetrol’s board of directors has approved an unpaid leave of absence for its president, Ricardo Roa Barragán, amid ongoing judicial investigations and growing pressure from unions, minority shareholders and political sectors.

In an official statement, the company said Roa “requested to use his accrued vacation days from April 7 to May 27, 2026,” and that the board also approved an unpaid leave requested by himself, “beginning on May 28 and lasting 30 calendar days.” This means he will be away from his duties for a continuous period extending through the end of June, after Colombia’s presidential elections scheduled for May 31 and June 21, if a runoff is required.

The decision comes in a context marked by two investigations led by the Attorney General’s Office. The first relates to an alleged case of influence peddling involving the purchase of an apartment in northern Bogotá, for which Roa has already been formally charged, although he has pleaded not guilty. The second concerns a possible breach of campaign finance limits during President Gustavo Petro’s 2022 presidential campaign, which Roa managed.

Both cases remain under review by judicial authorities, who will assess the evidence and issue a ruling (Colombia’s Top Prosecutor Charges Ecopetrol President in Alleged Influence-Peddling Case).

Roa’s temporary departure also follows pressure from some of the company’s main labor unions (Strike Threat Looms as Colombia Oil and Gas Union Calls for Ecopetrol President’s Removal), as well as minority shareholders (Ecopetrol Shareholders Loudly Heckle CEO Ricardo Roa at Annual Meeting as Leadership Dispute & Corruption Scandal Roils The Petroleum Company), and opposition political groups.

If this timeline holds, his potential return will coincide with the post-election period, ahead of the transition process with the new government set to take office on August 7, which is expected to appoint a new board and select a new president for the state-controlled oil and gas company.

During Roa’s absence, the board appointed Juan Carlos Hurtado Parra as acting president of Ecopetrol. According to the statement, Hurtado currently serves as executive vice president of hydrocarbons and has been the first alternate to the presidency since November 16, 2025.

He has “more than 28 years of experience in the energy sector, including roles as vice president of exploration, development, and production at Ecopetrol and has held executive positions focused on resource management and coordination. He is an electrical engineer, holds a specialization in Project Evaluation and Development, and has a Master of Business Administration (MBA) in International Oil and Gas.”
