  • Sunflower planting begins in northern Argentina.
  • Corn planting begins in north-central Argentina and eastern Argentina and progresses southward.
  • Wheat is in vegetative development.
  • Temperatures in northern Argentina can be quite warm.
  • Temperatures in central Argentina warming up to 70's-80's, but cool spells still possible.
  • Rainfall in the form of spring showers.


  • This is the main corn-planting month, especially in central Argentina.
  • Finish sunflower planting.
  • Begin early soybean planting in central Argentina.
  • Wheat is moving from vegetative development to flowering.
  • Temperatures warming up to the 80's or hotter.
  • Rainfall can be variable.


  • Corn planting complete in central Argentina.
  • Corn pollination starting for earliest planted corn.
  • Soybean planting in full swing.
  • Wheat moving from flowering to grain filling to maturity and early wheat harvest begins.
  • Sunflowers are flowering.
  • Temperatures now at summertime levels, heat waves are possible.
  • Summertime rains usually become more common.


  • Last corn planted in southern and northern Argentina.
  • Early planted corn pollinating in central Argentina.
  • Finish planting full season soybeans, planting double crop soybeans after wheat harvest.
  • Most of wheat harvested by the end of the month.
  • Temperatures now approaching maximum summer highs.
  • Rainfall usually abundant, but can have dry spells.


  • Early planted corn filling grain and approaching maturity.
  • By end of month, some early corn and sunflowers are starting to be harvested.
  • Finish wheat harvest by early January.
  • Finish planting double crop soybeans by early January.
  • Full season soybeans flowering and starting to set pods.
  • Maximum summer temperatures.
  • Summer rains usually abundant, but can have dry spells.


  • More corn and sunflowers now being harvested.
  • Later planted corn entering grain-filling phase.
  • Full season soybeans setting and filling pods.
  • Double crop soybeans flowering.
  • Sunflower harvest in full swing.
  • Maximum summer temperatures, but starting to cool by the end of the month.
  • Normal summer rainfall, may start to get lighter by the end of the month.


  • Corn harvest in full swing, remaining corn maturing.
  • Main month for soybean pod filling.
  • Harvest begins on early maturing soybeans.
  • Sunflower harvest completed.
  • Temperatures cooling down.
  • Rainfall getting lighter.


  • Corn harvest is wrapping up.
  • Full season soybean harvest in full swing.
  • Start to plant winter small grain crops.
  • Temperatures cooling to "fall-like" levels.
  • Rainfall continues to get lighter.


  • Finish harvesting full season soybeans.
  • Harvesting double crop soybeans.

  • Temperatures in northern Argentina are pleasant, temperatures in central Argentina are cool and frosts can be common, temperatures in southern Argentina are cold with snow possible.
  • Winter rains/snow can occur at any time.
  • Finish planting winter small grain crops in June.
  • Finish harvesting double crop soybeans in June.
  • Farmers are actively marketing their grain and watching for selling opportunities due to potential weather problems in the U.S.
  • Farmers are making plans for the next growing season and purchasing their inputs.
  • By the end of August early spring-like temperatures starting to return.
