South America Rainfall

We've seen a wide variety in rainfall so far this farming season in South America's major crop areas. Parts of Brazil are a little dry and in need of rain, whereas Argentina's situation is largely too wet. Here's a rundown from rainfall totals since August 1 as compiled by Joel Burgio. (Rainfall totals are Aug 1 through October 23):

Brazil-- The big northern soybean provinces of Mato Grosso and Goias are a little dry. Mato Grosso's average rain total is 2.62" for this year. Normal is 6.69". So this year's total is 61% BELOW normal.

In Goias, rainfall Aug 1-Oct 23 of 4.17" is 27% BELOW the normal 5.75".

Mato Grosso do Sul is a little above normal. 9.08" Aug 1-Oct 23 actual which is 31% ABOVE the normal 6.94".

Parana is somewhat dry. Province total rain since Aug 1 of 6.17" is 49% BELOW normal 12.24". Down about half.

Rio Grande do Sul, on the other hand, is pretty wet--similar to Argentina. That's no surprise because of the province's location in the far south of Brazil (Rio Grande do Sul is actually straight east of Corrientes and Misiones provinces in Argentina.) Rio Grande do Sul's total rainfall Aug 1-Oct 23 of 18.70" is 44% ABOVE the normal 12.95".

Argentina--- The major crop production areas that the market pays attention to are all wetter than average, and in some cases a LOT wetter than average.

Cordoba--- Aug 1-Oct 23 rainfall of 12.77" is almost 3 times normal. 193% ABOVE the normal 4.20".

Santa Fe--Total rainfall Aug 1-Oct 23 of 14.03" is 145% ABOVE the normal 5.37". More than twice the normal.

Entre Rios--- Total rainfall Aug 1-Oct 23 is 29.46". That is more than 3 TIMES the normal. This figure is 233% ABOVE the normal 8.84".

La Pampa--- Total rainfall Aug 1-Oct 23 of 13.56" is again over 3 TIMES above normal. That figure is 319% ABOVE the normal 4.19".

Buenos Aires-- this top-producing province has total rain Aug 1-Oct 23 of 11.04", right around double the average 5.21".

at what point on the calendar will the wet areas start to see a yield reduction?
