The La Niña weather phenomenon is expected to pose significant challenges to global coffee production, according to hEDGEpoint Global Markets. The phenomenon could lead to lower temperatures and frost in Southeast Brazil, intense rains in Indonesia and Colombia, and increased risks of tropical storms and hurricanes in Central America. However, predicting its exact impact is difficult due to various factors influencing crop yields. If La Niña becomes active during key development stages from the second quarter onwards, it could potentially boost coffee production.
