The La Niña weather pattern is expected to persist for the next month or two before fading out in early 2026, according to the U.S. Climate Prediction Center. That does not mean much for U.S. weather patterns, but it could limit precipitation over South America’s growing season, meteorologists say.
In a La Niña pattern, stronger-than-usual trade winds push warm water toward Asia. That results in an upwelling of cold, nutrient-rich water to the surface off the west coast of the Americas, with implications for global weather patterns. The current La Niña pattern has been relatively weak, analysts have noted.
Meteorologists have forecast that the current weak La Nina could result in hotter and dryer-than-normal conditions across Argentina during December and January, noted crop consultant Dr. Michael Cordonnier earlier this week. That hasn’t yet materialized, he noted, with crops, in fact, doing quite well with 61% of soybeans rated good or excellent. He noted, though, that less than half the soybeans have been planted.
Cordonnier left his Argentine soybean estimate unchanged this week at 49.0 MT with a neutral bias. If the anticipated La Niña impact takes hold, the estimate is probably too high, he said. If the impact doesn’t materialize, the estimate is probably too low.not materialize, then this estimate is probably too low. Read more from Pro Farmer.
