Mixed Weather Conditions Affecting Brazil’s Early Safrinha Corn Growth

Brazil’s safrinha corn planting has progressed well, but mixed weather presents challenges. Some areas face drought, particularly in eastern regions, while states like Mato Grosso enjoy favorable conditions. Rain forecasts offer hope, yet the overall situation remains critical as the dry season looms.

Brazil’s safrinha corn planting has now caught up to or surpassed the typical pace, yet the country faces mixed weather conditions. While certain regions experience advantageous weather, many areas are grappling with insufficient rainfall. Drier weather has persisted in southern and eastern Brazil, with temperatures rising into the 30s Celsius (upper 80s to upper 90s Fahrenheit). Satellite data indicates that these regions often exhibit below-normal soil moisture levels, particularly from Rio Grande do Sul to Piaui.

In the southern state of Rio Grande do Sul, which predominantly grows full-season corn and soybeans, rainfall is less critical at this stage since crops are already in filling or harvesting phases. In contrast, regions such as Parana, Mato Grosso do Sul, Minas Gerais, and Goias rely heavily on rainfall to support their safrinha corn crop, which must sustain moisture during critical pollination phases before the onset of wet season rains in mid-April to early May. The reliance on favorable weather emphasizes the significance of this year’s corn yield as safrinha accounts for 75% of Brazil’s corn production.

Recent weather developments brought some relief, as a front from Argentina produced scattered showers over the past week, particularly benefiting Mato Grosso do Sul with nearly normal rainfall levels. Future forecasts indicate this front may linger, predicting additional rainfall of 25-50 mm in certain areas. However, the prospects remain grim for east-central and northeastern Brazil, where rainfall forecasts are bleak and many regions continue to face drought conditions, especially in the San Marcos Valley.

Conversely, Mato Grosso, Brazil’s leading corn-producing state accounting for about 50% of safrinha output, is currently experiencing favorable weather conditions. Regular wet season showers have been beneficial, and soil moisture levels appear near normal, suggesting a positive outlook for corn growth in that area. The outlook for the next six weeks will be critical, as the dry season approaches and the corn growth relies on available moisture.

In summary, Brazil’s safrinha corn production currently faces challenges due to mixed weather conditions. While some regions, particularly Mato Grosso, are benefiting from adequate rainfall, others are marked by drier conditions that jeopardize corn growth. With the approaching dry season, the coming weeks will be paramount in determining the overall yield of the safrinha corn crop, which is vital to Brazil’s agricultural output.
