April – July are the best months to visit Victoria Falls because its water flow will be at peak levels. April and May have the most water flow at the Falls, and these are shoulder months to visit Zimbabwe and Zambia when safari costs and crowds will be less.
June – September are the peak travel season because these are the driest months of the year. The Falls’ water level will still be great, and if you’re going on a safari, wildlife is easy to find around water holes.
These months have the highest prices and crowds, so book your lodge and tours as far in advance as possible.
November – March are the rainy and off-season months. It will be wet and humid, visibility will be poorer, and the falls’ water level will be low. These are also not good months to go on safari in Zimbabwe or Zambia when wildlife will be hard to find because they won’t need to gather at watering holes.
You can score some great accommodation deals during these months, though, and it can feel like you have Victoria Falls to yourself!
