Executive summary
- Multi-annual precipitation deficits combined with above-average temperatures and a sequence of heatwaves are the cause of the long-running and extensive drought in central-southern South America.
- From August 2022 to March 2023 the drought has diminished in Brazil and moved southwards, now affecting mainly northern Argentina and Uruguay.
- Hydrology and vegetation are severely affected by the drought, with impacts on crops, rivers flow and energy production. Widespread impacts due to the drought can be linked to the estimated 3% GDP reduction in 2023 in Argentina.
- After three years of La Niña conditions, the tropical Pacific Ocean has entered neutral ENSO conditions and a transition to an El Niño phase is forecasted for the coming months.
- Seasonal forecasts point to warmer temperatures, close to average precipitation and lower than average river flows.
