The La Nina weather pattern characterized by unusually cold temperatures in the Pacific Ocean could emerge in the second half of 2024, following a strong El Nino year, a U.S. government weather forecaster said on Thursday.
The pattern typically brings higher precipitation to Australia, Southeast Asia and India and drier weather to grain and oilseed-producing regions of the Americas.
“Even though forecasts made through the spring season tend to be less reliable, there is a historical tendency for La Nina to follow strong El Nino events,” the National Weather Service’s Climate Prediction Center (CPC) said.
The current El Nino weather pattern, which caused hot and dry weather in Asia and heavier than usual rains in parts of the Americas, is likely to give way to neutral conditions during April-June 2024, the CPC said.
CPC said in its monthly forecast there is a 55% chance that La Niña conditions develop between June and August.
“La Nina is likely to affect the production of wheat and corn in the US, and soybean and corn in Latin America including Brazil,” Sabrin Chowdhury, head of commodities at BMI said.
Last year India, the world’s biggest rice supplier, restricted exports of the staple following a poor monsoon, while wheat output in No. 2 exporter Australia took a hit. Palm oil plantations and rice farms in Southeast Asia received less than normal rains.
“The development of La Nina is beneficial for the Indian monsoon. Typically, the monsoon delivers abundant rainfall during La Nina years,” said an official with the India Meteorological Department.
The June-September monsoon, which is vital for India’s $3 trillion economy, brings nearly 70% of the rain the country needs to water crops and replenish reservoirs and aquifers.
