Drier weather returns to Argentina

Wetter weather shifts north into central Brazil.

Brazil continues to be in a favorable position as soybean planting advances well above the five-year average and last year. The timely planting of soybeans is important as it allows the safrinha crop, or second-corn crop, to be planted and reach critical maturing stages before Brazil’s dry season sets in.

According to data from WeatherTrends360, October 2021 trended as the fifth wettest October in more than 30 years for the major soybean growing regions of Brazil. However, the story was much different in Argentina’s primary soybean regions as this was the third driest October in the same time frame. 

The first week of November, week-ending November 6, brought some changes in the precipitation trends with drier-than-normal conditions in Brazil’s major producing regions while much of Argentina’s producing region was wetter than normal as much needed rain arrived. However, the wetter fortunes will not continue into the second week of November for Argentina.

In the second week of November, wetter trends will retreat north to central Brazil while southern Brazil and a large part of northern Argentina see drier weather settle in. According to WeatherTrends360, the second week of November will be the second and third wettest in 30-plus years for Mato Grosso and Goiás, respectively. Meanwhile, Rio Grande do Sul and the major soybean producing region of Argentina will see the third driest second week of November in the same period of time. 

Drier conditions may not be all bad news, especially for the Brazilian state of Paraná, as too much rain in October may result in some replanting. The second week of November is forecast to be the seventh driest in 30-plus years for Paraná. Drier weather will not receive as warm of a welcome in Argentina following a dry October. Less favorable planting conditions may be a sign of trouble for soybean yields here.

While precipitation trends will be spilt across Argentina and Brazil, the common theme in the second week of November 2021 will be cooler-than-normal temperatures. This is forecast to be the second coolest second week of November since before 1991 for the major soybean region of Brazil and the sixth coldest in the same time span for the major soybean region of Argentina.
