The advance of rains over producing areas of rice In Mercosur, the planting calendar for the 2026/27 crop is beginning to take center stage, with fewer days available for soil preparation and sowing. This assessment comes from Sergio Cardoso, an analyst in the crop supply chain. ricewhich points to the end of August as a time when the weather factor starts to gain importance for the new season.
According to Cardoso, there are still regions with areas designated for rice cultivation that need to be prepared, while the sequence of rainfall limits work opportunities in the fields. For now, the scenario does not indicate problems for the harvest, but it reduces the existing slack in the calendar.
In Paraguay, some regions are already starting sowing in August. From September onwards, Rio Grande do Sul, Argentina, and Uruguay will also move towards their planting windows. With rain forecast, attention is turning to the number of days that machinery and teams will be able to enter the fields.
The analyst notes that an extreme weather event is not necessary to impact production. Persistent rains can delay operations, concentrate work in short periods, and push some planting to less favorable times.
The planting season also affects the yield potential. The further the rice is from the recommended window for each region and cultivar, the greater its exposure to less suitable temperature and radiation conditions during important stages of development.
Cardoso believes it is still too early to project a reduction in planted area, productivity losses, or problems with the harvest. Even so, the number of days available to prepare the fields and sow within the optimal windows emerges as one of the first climatic variables to be monitored in the 2026/27 harvest.
