El Niño is an evolving climate phenomenon characterized by warmer-than-usual water temperatures in the eastern equatorial Pacific, with global impacts expected to intensify from late 2026 into early 2027. According to Drew Lerner of World Weather, Inc., the event triggers a chain reaction of weather anomalies—including floods, droughts, and temperature shifts—that significantly disrupt international fresh produce supply chains.
How Does El Niño Disrupt Global Produce Supply Chains?
The transition toward an El Niño pattern typically begins in Southeast Asia and northern South America before spreading to India, central Africa, and northeastern Australia. Drew Lerner notes that the phenomenon creates extreme weather that directly impacts the flowering and pollination of fruits and vegetables. For instance, increased moisture levels can lead to fungal diseases, while adverse weather often reduces bee activity, lowering overall crop yields.
In South America, the impact is particularly acute. Northern Chile, Peru, and Ecuador often face heavy flooding, while parts of Colombia, Venezuela, and Central Mexico may experience drought conditions. Conversely, southern Brazil, Uruguay, and eastern Argentina frequently see wetter-than-normal conditions. Beyond agriculture, the International Research Institute for Climate and Society at Columbia University notes that reduced anchovy production off the coast of Peru is often the most significant economic loss during these events.
El Niño is caused by a massive low-pressure system forming over the eastern Pacific. This system lifts warm, moisture-heavy air into the atmosphere, which is the primary driver behind the resulting global precipitation anomalies.
What Should North American Importers Expect?
North American importers face two primary risks: supply shortages and quality degradation. Because North America relies heavily on imports from South America and, increasingly, Southeast Asia, drought or flooding in these regions directly drives up prices. Lerner advises importers to conduct exhaustive inspections of goods, as wet weather diseases thrive during El Niño, potentially compromising the shelf-life and safety of imported produce.
Domestically, the impact is most pronounced during the winter months of the fourth and first quarters. California, Florida, and South Texas—the primary hubs for winter production—may experience flooding. However, there is a silver lining: the increased humidity and precipitation associated with El Niño often reduce the risk of damaging freezes and cold surges in southern states, while also lowering irrigation demand in the southwestern desert.
Comparison: Regional Weather Impacts
| Region | Expected Trend |
|---|---|
| Northern Chile/Peru/Ecuador | Increased flooding and rainfall |
| Southern Brazil/Uruguay | Wetter conditions throughout winter/summer |
| Northeastern Brazil | Unusually warm and dry |
Frequently Asked Questions
How soon will the effects of El Niño be felt?
According to Drew Lerner, the phenomenon is currently evolving and is expected to be officially underway within the next few weeks, with the most significant impacts appearing from late 2026 through early 2027.
Does El Niño always cause crop failure?
Not necessarily, but it creates “extreme weather” that increases volatility. While wet biases can hurt pollination and cause disease, the phenomenon also reduces the likelihood of damaging cold surges in North American growing states.
Why are prices expected to rise?
Prices generally climb because extreme weather leads to reduced harvest volumes. As supplies tighten globally, importers face higher costs to source consistent produce from affected regions like South America and Asia.
If you are an importer, prioritize supplier diversification now. By sourcing from regions less likely to be hit by the specific precipitation patterns of the upcoming El Niño, you can help stabilize your inventory costs.
