Most part of São Paulo state registered high temperatures in early September. This scenario brought concerns for citrus growers, who may face another year of significant heat waves.

Climatempo says that heat waves in September have become more common in most part of Brazil; however, they have been more intense and are lasting longer.

2024/25 CROP – São Paulo state and Triângulo Mineiro may harvest 215.78 million 40.8-kg boxes in the 2024/25 orange season, according to data released by Fundecitrus on September 10. The volume may be 30 % less than in the crop before, which registered average production, and below the first projection, of 232.38 million boxes.

The decrease is related to the smaller fruit size, due to the dry and warm weather. The weather also accelerated the harvesting pace, since it influenced the ripening. More than half of the crop can be harvested in this dry weather scenario because rains are forecast only for late September.

The volume of rainfall was small in almost all areas in the citrus belt, except in the southwestern region of São Paulo. Fundecitrus indicates that the only area where the production is expected to increase in this season is the southwest of SP – the harvest may be 19 % higher than in 2023/24. In other regions, the production decrease can be between 28 % and 60 %.
