Rains ease in Argentina and return to Central and Southeast Brazil

Late January rain may have salvaged some late-planted crops in Argentina/Southern Brazil.

Beneficial rains continued in the growing regions of Argentina while precipitation was spottier in southern Brazil.

Temperatures cooled down considerably in Argentina, but southern Brazil was hot. The final few days of January 2022 will bring drier weather across much of Argentina and southern Brazil, but the chance for precipitation returns to the forecast closer to the first weekend of February. 

The final full week of January 2022, week-ending January 29, was the fifth coolest and sixth wettest in more than 30 years for the growing regions of Argentina, according to data from WeatherTrends360. Although rainfall is desperately needed and may be beneficial for some later-planted crops, the rain may have arrived too late to salvage some of the early-planted crops. 

Meanwhile, precipitation was spotty in southern Brazil. Very hot in parts of southern Brazil and this was the second hottest final week of January in 30-plus years for Rio Grande do Sul. Hot weather tends to zap soil moisture quickly, so spotty rainfall was likely not enough to significantly replenish moisture in the hotter conditions. However, temperatures cooled down significantly by the weekend.


The final few days of January 2022 will bring drier weather across the areas that still need rain, namely growing regions of Argentina and southern Brazil. Showers will move back into the forecast as we approach the first weekend of February 2022.

For the week ending February 5, temperatures will trend closer to normal, if not a bit below normal, in the major growing regions of Argentina; precipitation will likely be below normal. Temperatures will trend the fifth to sixth warmest since 1992 if not earlier in southern Brazil for the first week of February. Much of Southeast and Central Brazil will trend colder and wetter than normal.

According to WeatherTrends360, this will be the second coolest and eighth wettest start to February in for Mato Grosso in the same time frame.
