Chapter 2 – Climate change dynamics
South Africa’s climate system has displayed an atypical ENSO cycle since 2020, including one El Niño event, two moderate-to-strong La Niñas and two weak La Niñas. These patterns have shaped recent production outcomes and set the stage for the coming season. Figure 2 provides historical ENSO distribution context, showing the relationship between El Niño, La Niña and neutral phases over time.
