# South America may trend slightly drier | World Grain

> World Grain reports on September 1, 2025 that South America may see another weak La Niña, which could mirror last year's delayed seasonal rains that disrupted early corn and soybean planting. World Weather Inc. argues the earlier dryness had other atmospheric causes and that current Pacific conditions are not strong enough for a full La Niña.
