La Niña weather challenges in South America agricultural regions
As the U.S. harvest starts to wind down, attention turns to the weather in South America to see how their growing season is shaping up. La Niña will certainly play a role for certain parts of South America and we’re already seeing telltale signs of the oceanic cycle’s impact. During the South American growing season when La Niña is present there is a greater likelihood of drier than normal conditions in southern Brazil and northern Argentina.
Indeed, in southern Brazil from September 1st through November 12th, 2020, we have seen some of the driest conditions of the past 30 years for this time period with temperatures well above normal. Dry conditions extend into some of the far northern portions of Argentina, however, precipitation was closer to normal farther south across the state of Buenos Aires. Dry weather led to some issues with planting of soybeans in Brazil.
Looking ahead to mid-November (November 13th-19th, 2020), drier than normal conditions are expected to continue for Rio Grande do Sul in Brazil, however, just a bit farther north, precipitation will be greater than normal, across states like Parana, Mato Grosso do, Sul, and Minas Gerais. Temperatures will trend near to slightly above normal in southern Brazil, while much of the rest of Brazil trends colder than normal.
In Argentina, mid-November 2020 will yield continued dry conditions for northern areas with below normal temperatures. As we head into the latter half of November, temperatures are forecast to turn warmer across the bulk of Argentina, although drier conditions may persist in parts of northern Argentina.
