According to weather experts, a La Niña weather event is expected to return this fall for a second year, which could have an effect on yields and export demand. During a La Niña, cool phase trade winds tend to be stronger than usual across Asia while the West U.S. experiences an upwelling of cold, nutrient-rich water to the surface. This can also mean warmer than normal fall/winter temperatures in the South and a cold winter in the North. While the cycle has shown benefits in the past for the following summer on winter wheat in the northern hemisphere and soybean in the southern hemisphere, growers should consider that in most years when La Niña is present later in the year, yields generally have trended lower.
