Tridge summary

The article discusses the potential impact of the upcoming La Niña weather phenomenon on agricultural crops in Brazil, particularly focusing on the spring and summer seasons. While La Niña typically leads to reduced rainfall in the South and increased rainfall in the North, recent experiences have shown variability, and it remains uncertain how it will affect rainfall patterns this year. Despite the cold start to the season, the risk of frost in agricultural areas is low, and humidity is welcomed relief for coffee plantations that have previously suffered drought. However, there are concerns that the rains in the Center-South may become more spaced, potentially leading to challenging conditions for summer crops, especially soybeans. The article also highlights the need to consider other climate factors, such as the warming Atlantic, which can impact Brazil's climate. For coffee growers, the current climate outlook is somewhat optimistic, with a transition period expected that may prevent prolonged drought or excessive rainfall, although predictions vary regarding the strength of La Niña and its impact on rainfall.

"What is known is that, in most cases, La Niña reduces rainfall in the South and generates an increase in the North. But there has already been a year when it rained above average in the South, despite the phenomenon", says Felipe Gustavo Pilau , professor at Escola Superior de Agricultura ´Luiz de Queiroz´ (Esalq) and partner of the meteorology startup Weather Service. "We will have to wait until October to have a more assertive panorama", he says. It is a fact that spring began more favorable to agricultural crops than it has been in the last two years. "The South region is more rainy than normal. In the Southeast and in the central region, which had little rain, the situation is getting regularized", says Pilau. The arrival of precipitation should collaborate for the planting of grains within the ideal window. For coffee plantations in Minas Gerais and São Paulo, which suffered from periods of severe drought for two years, the humidity is also a relief. Although spring started ...
