Before You Book: Practical Tips
Season, health, clothing and the one swimming question everyone asks.
Pick Your Season
The Zambezi's flood season runs February to May with maximum flow in April, and the falls carry roughly one tenth of that volume at the low point around November. That trade-off shapes everything: full water and heavy spray in the first half of the year, thinner falls but the best rafting and Devil's Pool access from August into early December. Rafting can close at peak flood around April and May.
The best time to visit guide walks through the trade month by month.
Malaria
The CDC classifies Zambia as a high-malaria-risk country nationwide, and in Zimbabwe the risk is concentrated in the north and east, which includes Victoria Falls. Risk peaks during and just after the rains, roughly November to April. Atovaquone-proguanil is the CDC's first-line prophylaxis for this region, started 1 to 2 days before arrival, taken daily and continued for 7 days after leaving.
General guidance is to see a doctor or travel clinic 2 to 6 weeks before departure to get the right prescription.
What to Wear
On the cruises, layer up after dark: July nights at Victoria Falls average lows around 10°C, and it feels colder on moving water. For rafting, wear quick-dry clothing and sturdy closed-toe shoes, because the hike into and out of the Batoka Gorge is steep and you will be soaked all day. Bring sunscreen and a change of clothes for after.
Leave large bags and luggage behind, since the Maano listing does not allow them.
Can You Swim in the Zambezi?
Not freely, no. Hippos and Nile crocodiles are common on the upper Zambezi above the falls, which is exactly why the cruises stay on the boat and swimmers stay out of the water. The one exception is where an operator runs a controlled swim: Devil's Pool on Livingstone Island at the lip of the falls, open roughly mid-August to mid-January when water levels are low enough, and closed during high water.
It is a guided trip, reported at around $90 to $158 depending on the meal package. Read the Devil's Pool guide before planning it.
The Moonbow
On the three nights around each full moon, a lunar rainbow forms in the spray of the falls. Moonbows are strongest in the high-water months when spray volumes peak, and guided night tours of the Rainforest run about 2 hours on those nights. The moonbow guide explains when to look and how it works.
