Rainfall in Victoria Falls is highly seasonal, characterized by a distinct "Wet Season" and "Dry Season." During the peak of the wet season, which runs from November to April, it rains almost every day, typically in the form of dramatic afternoon thunderstorms. January and February are the wettest months, receiving an average of 150-200mm (6−8 inches) of rain each. In contrast, during the dry season from May to October, it almost never rains; months like July and August often record 0mm of precipitation. This cycle dictates the flow of the Zambezi River; by the end of the rainy season in April, the falls are at their "peak flow" and the spray is so intense it creates its own "rain" for anyone walking the viewing paths. By October, the lack of rain can cause the "Eastern Cataract" on the Zambian side to dry up completely. For a 2026 traveler, the "shoulder months" of May and June offer the best balance: virtually no actual rain from the sky, but a thunderous flow of water over the falls from the preceding months of heavy storms.
