Wanderlust World Wanderlust World Victoria Falls doesn’t have a single “water temperature” because the Zambezi River plunges over a basalt cliff in a curtain‑like cascade rather than pooling in a measurable basin. The river’s temperature upstream varies seasonally (typically 20–28 °C / 68–82 °F), but the fall itself is a chaotic mix of spray, air, and rapids—no stable body of water to measure.
