Weather punishes coffee plantations in Alta Mogiana, with losses reaching 30%

The coffee harvest in Alta Mogiana, São Paulo, is nearing its end with significant losses. Producers are reporting a drop in productivity of up to 30%. The main reason was adverse weather. The region suffered six months of drought between late 2024 and early 2025, in addition to high temperatures during the flowering period.

Coffee grower Rafael Stefani explains that flowering didn't develop as expected, even with the return of rain in October. The intense heat prevented the flowers from setting. According to him, the drought struck again in February, with more than 30 days without rain. This problem compromised fruit set.

During the harvest, producers confirmed the impact. Yields dropped. Poorly granulated and lighter beans required more fruit to complete the weight of a bag. "We spent more coffee to produce the same volume," says Stefani. The situation was repeated in other regions of the country.

Despite the losses, the 2026 harvest may have a better outlook. Rains in May and July helped restore some of the crops' vigor. "The plants are healthier," says Stefani.
