The falls look different month on month, in direct relationship to the rains and how full and fast flowing the Zambezi is, so it’s important to plan your visit, if you don’t want to be disappointed by too much spray or tiny trickles.
December to March is the height of summer and the rainy season, with often dramatic thunderstorms in the afternoons. In December, the Zambezi is low, but begins to swell towards the end of the month as rains fall upstream.
In January and February, the water levels are climbing. White water rafting often stops on the Zambezi in February because the river is too high. Similarly, it’s not possible to use the Devil’s Pool in January and February.
The river is in full flood during February and March, when as much as 540 million cubic meters of water fall over the edge every single minute. At this time, the plumes of spray billowing up from the base of the falls can obscure the view. You can hear it, but you can’t really see it – a bit like standing inside a noisy cloud.
April, May and June, at the end of the rains, is when the most water is rushing over the falls. This is spectacular, but be aware that mist can obscure views from several lookout points. This is the best time for a helicopter ride over the falls.
July and August are the best time to see the falls, when slightly lower water levels mean less spray and better visibility. This also coincides with the best time for game viewing in the region, too. Days are warm now, hitting max 28°C.
September, October and November mark the end of the dry winter season, and the falls are at their lowest. The curtain of water splits into individual channels of falling water now. It’s not as spectacular, but you do have the advantage of being able to peer right down to the base of the gorge, without spray interfering with the view. Head to the Zimbabwe side for the best views. Horseshoe Falls, which has the least volume of water, is the first to dry up, usually between October and November. This is peak white water rafting season. Temperatures are high, sometimes hitting 40°C in September and October, before the first rains arrive in November. Game viewing is superb now, if you can stand the heat.
