Argentina Weather: Irregular Rainfall Forecast for Key Farm Region

Argentina’s agricultural sector faces continued uncertainty as rainfall remains below average across key growing regions, threatening crop yields and potentially impacting global food supplies. The situation, compounded by uneven weather patterns and lingering drought conditions, is raising concerns among farmers and agricultural analysts.

The country’s National Weather Service forecasts normal to below-normal rainfall for the remainder of the Pampas region over the next three months, according to reports. This follows a period of erratic precipitation, with some areas experiencing sporadic rainfall while others, notably parts of Buenos Aires and Cordoba provinces, have seen very little. January 30th reports from the Secretariat of Agriculture, Livestock and Fisheries (SAGyP) detailed the uneven distribution of rainfall, with Santa Fe province benefiting from more consistent precipitation.

The dry conditions are already impacting corn crops in Buenos Aires and Cordoba. SAGyP officials have warned that yields in some areas of Cordoba could face significant cuts due to the lack of rain. While corn in Santa Fe is reportedly in better condition, leafhoppers have been detected, requiring careful management to prevent widespread damage. Early-planted soybeans in Buenos Aires and Cordoba are also showing signs of stress, with some loss of flowers reported, though they still have the potential to recover with sufficient rainfall.

The delayed 2024/25 soybean harvest, hampered by sodden fields earlier in the season, is now facing the prospect of being sped up by the continued dryness, according to the Buenos Aires grains exchange. However, this acceleration comes with the risk of reduced yields if moisture levels remain insufficient. The exchange noted on April 23rd that the dry weather should help with the harvest, but also highlighted the underlying concerns about overall production.

Soybean planting is nearing completion, with 99.5% sown as of January 28th, according to the Buenos Aires Grain Exchange (Bage). However, the condition of the crop has deteriorated slightly, with nearly 84% now rated as normal-to-good, a decrease of 2.3 percentage points from the previous week. Crucially, the area with adequate-to-optimal soil moisture has declined by 2.6 percentage points to 64%, underscoring the growing concerns about water availability.

Corn planting is also almost finished, reaching just over 97% complete. The situation in Argentina is unfolding against a backdrop of broader climatic challenges in South America. A report from January 20th highlighted a divergence in weather patterns across the continent, with northern Argentina receiving heavy rainfall while central and southern regions continue to struggle with dryness. A heat wave is forecast to develop in the 6- to 10-day window, potentially exacerbating the situation for corn and soybeans during critical reproductive stages.

The uneven rainfall patterns in Argentina are occurring as Brazil, another major agricultural producer, is also revising its soybean output forecasts downward. Brazil’s crop agency recently cut its 2025/26 soybean output forecast, adding to the global concerns about supply. This confluence of factors – drought in Argentina, uneven rains across the continent, and reduced forecasts in Brazil – raises the specter of tighter global supplies and potentially higher prices for soybeans and corn.

The impact of these conditions extends beyond Argentina’s borders. As a major exporter of agricultural commodities, any significant reduction in Argentina’s harvest will have ripple effects on international markets. Countries reliant on Argentine soybeans and corn for food and animal feed could face increased import costs and potential shortages. The situation is being closely monitored by traders and producers worldwide, who are assessing the potential implications for global food security.

The SAGyP is continuing to monitor the situation and provide support to farmers. However, the long-term outlook remains uncertain, dependent on whether sufficient rainfall arrives in the coming weeks and months. The combination of heat and limited moisture poses a significant threat to crop development, and the potential for further yield reductions remains high. The current conditions underscore the vulnerability of agricultural production to climate variability and the importance of proactive measures to mitigate the risks.

The challenges facing Argentina’s agricultural sector are not isolated. They are part of a broader pattern of climate-related disruptions affecting food production around the world. From cold snaps in the Upper Midwest of the United States to droughts in South America, extreme weather events are becoming increasingly frequent and intense, posing a growing threat to global food security. The situation in Argentina serves as a stark reminder of the interconnectedness of the global food system and the need for international cooperation to address the challenges of climate change and ensure a sustainable food supply for all.
