La Niña is here: What does it mean for Latin America and the Caribbean?
The phenomenon is expected to last until April, with more humidity in Central America and northern South America, and more droughts in the center and south of the region
La Niña, a phenomenon characterized by the cooling of the Pacific Ocean and which has been anticipated since September 2024, is already here. At the beginning of January of this year, international meteorological agencies announced that a weak Niña is expected to persist until April, with a 59% probability, and to evolve into neutral conditions in May, with a 60% probability. La Niña is a phenomenon of climatic variability that alternates with El Niño and neutral conditions over periods that can last months or years. While La Niña usually lasts longer, El Niño, which predominated between mid-2023 and early 2024, occurs in shorter periods and is characterized by warmer ocean temperatures.
