The south-central region will see the return of rainfall in the second half of July.

After a week marked by low temperatures and predominantly dry weather, the Central-South region of Brazil is expected to experience a change in weather patterns in the coming days. According to an analysis by DATAGRO, based on models from European Centre for Medium-Range Weather Forecasts (ECMWF)The second half of July is expected to be marked by the return of rains and the passage of new cold fronts over important producing regions of the country. Until the end of the first half of July, cold weather is expected to persist in southern Brazil and parts of São Paulo and Mato Grosso do Sul. However, between July 11th and 12th, the first rainfall should reach Rio Grande do Sul, Santa Catarina, and Paraná, with accumulations of up to 30 millimeters. Following this, the rains will advance to Mato Grosso do Sul, São Paulo, and Minas Gerais, where volumes could vary between 15 mm and 30 mm, mainly in the extreme south of Mato Grosso do Sul, the microregion of Piracicaba (SP), and southern Minas Gerais. In other areas, accumulations should be more modest. Last week, the presence of polar air masses caused temperatures near or below 0°C in several locations in the Southern region. In the winter corn-producing areas of Paraná, Colombo recorded a minimum of 0.3°C, while other regions of the state had temperatures between 3°C and 5°C. In Rio Grande do Sul and Santa Catarina, thermometers fluctuated between -1°C and 4°C. In Mato Grosso do Sul, minimum temperatures ranged from 3°C to 8°C, with light frosts occurring in lowland areas, while in São Paulo temperatures ranged between 10°C and 14°C. The absence of rain over the last few days favored the progress of the sugarcane, second-crop corn, and coffee harvests in practically all of the Center-South. In the South, however, recent rainfall was concentrated mainly in Santa Catarina, with accumulations close to 90 mm, and in Rio Grande do Sul, with average volumes of around 20 mm. In Paraná, rainfall was limited to the southern part of the state, while the north remained dry, allowing field operations to continue. Medium-term models indicate that after July 18th, rainfall should intensify across much of the Central-South region. New cold fronts are expected to arrive by the end of the month, a scenario that could cause occasional interruptions to sugarcane, corn, and coffee harvesting. Despite the return of rain, the forecast indicates that temperatures will remain above the climatological average in much of Brazil during the second half of July, influenced by the strengthening El Niño phenomenon.
