THE DATAGRO On Monday (4), it released the agroclimatic outlook for the period from May 4 to 13, 2026. The consultancy predicts the arrival of a more intense cold front on Friday (8), which should cause the lowest temperatures of the year so far.
For today, rain is forecast between northern Rio Grande do Sul and southern Paraná, with amounts between 5 and 30 mm. In the following days, the weather will become stable again in most of Brazil. Rainfall will be restricted to the far north due to the influence of the Intertropical Convergence Zone (ITCZ). Temperatures should gradually rise throughout the week, with no indication of heat waves forming.
Intense cold front advances over the South.
On Friday (8), a new, more intense cold front is expected to bring rain to the entire Southern region. The system may subsequently advance to Mato Grosso do Sul and São Paulo. The expected rainfall amounts vary between 20 and 30 mm. Only a strip between southern Mato Grosso do Sul and northern Paraná presents a risk of heavier rainfall.
A mass of cold air of polar origin is expected to reach Rio Grande do Sul between Friday (8) and Saturday (9), advancing to other states in the following days. The peak of the cold is expected between Sunday (10) and Monday (11). There is a possibility of frost between Rio Grande do Sul and southern Paraná. In São Paulo, minimum temperatures should be close to 10°C.
Conditions favor agricultural operations in the field.
In other producing regions, no rain is expected at the beginning of May, which should keep temperatures high. Weather conditions remain favorable for the progress of field operations, such as the sugarcane and coffee harvests. In Paraná—a state with the lowest soil moisture levels among the main producers—the expected rainfall should contribute to moisture recovery.
