It's been pretty dry in much of South America this year. The maps below are for 30 days, 90 days and 180 days % of average precipitation:

The forecasts below come from the GFS/US model. Some rains with relief in the northern areas during week 1, then the southern areas during week 2.

It's still early in the planting season.

Thanks Mike. This is what I really want to start learning more about. Nice to see other areas where crops are grown when I had no clue a few months ago.

Rains for Brazil the next 2 weeks are widespread and copious. Bearish for beans:

Argentina will be drying out.

Weather in S.Brazil and N.Argentina is looking more bullish.

Argentina will start drying out this week, and S.Brazil will start drying out later this week.

Note: There are still alot of rains in dry Central areas of Brazil in the next several days to 2 weeks, it's S.Brazil and Argentina that will be heading into a dry period.

S.Brazil just got some huge rains too. The map below is rain the last 5 days.

You are right about the SA soils. They don't hold moisture as well as ours.
