The Benguela Current system, spanning the coasts of Angola, Namibia and South Africa, is one of the world’s major eastern boundary upwelling systems. It supports highly productive fisheries and influences regional rainfall, yet its long-term variability and predictability remain poorly understood. My PhD investigates whether the Benguela system can be predicted on seasonal to decadal timescales—looking at what drives its variability, whether we can actually forecast it, and how such predictions could inform decisions for fisheries, agriculture, and coastal communities.
