Livingstone in May

April through October gives you the sweet spot - dry season means clear skies for helicopter rides and comfortable temperatures for game drives. But timing depends on what you want from Victoria Falls. April and May show the falls at full power after rainy season - spectacular but you'll get soaked on the viewing paths. July through September offers the best wildlife viewing as animals gather around water sources. This is peak season though, so book early and expect higher prices. October gets brutally hot - 40°C days aren't uncommon - but it's the best time for white-water rafting as water levels drop to expose the biggest rapids. November through March brings rain, flooding, and humidity. Some activities shut down and the falls disappear behind mist. But accommodation costs plummet and you'll have the place mostly to yourself.
