Month by month
Forget everything you assume about wet and dry: the Okavango floods in the middle of the dry season. Understand that one fact and every month of the Moremi calendar falls into place.
If you only want the answer
May to August. July here is genuinely rainless, 0 mm on the thirty-year average, against 161 mm in January. Nothing concentrates animals like water that has stopped falling.
The periods below are how this park actually divides its year, with thirty-year climate averages against each month. Averages hide bad years: a dry January still happens, and so does a wet July.
Green season
Peak rain (around 100 mm a month) and the hardest months: thick bush, dispersed game, waterlogged tracks and possible closures. Superb birding, lowest rates, and the national fishing ban runs these two months.
Shoulder
Rains taper, animals finish raising young, roads recover and the first floodwater arrives in April. Quiet, green and excellent value.
Prime
The dry season begins and the flood spreads. Very good game viewing, ideal boating, shoulder rates: the best value-to-quality month of the year.
Prime
Top tier begins. Game concentrates, wild dogs den, the flood keeps rising. Nights fall to around freezing in open country, so pack real winter layers for dawn drives.
Prime
The flood peaks in mid-winter: prime boating, prime game viewing, peak rates and the busiest campsites. July mornings are the coldest of the year.
Shoulder
Still excellent, and the big elephant and buffalo herds are at their densest along the Khwai and the lagoons as the flood recedes. Hazy, dramatic light.
Shoulder
Superb big game and punishing heat: mean maximums near 35°C and days over 40°C are common. Water activities become limited as the flood drops.
Green season
First rains break the heat, game is still good but dispersing, mokoro improves locally, and shoulder-season bargains appear.
Green season
The green season proper: storms, breeding plumage, newborn antelope, low rates and deteriorating roads.
Climate figures are Open-Meteo climate normals, 1991 to 2020, measured at -19.3, 23.3. Prime, shoulder and green are worked out against this park's own year, not a fixed threshold: the four months with the least rain, the four with the most, and the rest in between. Full charts on the weather page.
Two separate water events shape Moremi, about five months out of phase. Local rain falls from November to March, greening the bush and dispersing the game. The flood is a different thing entirely: rain that fell in the Angolan highlands between December and March travels roughly 1,200 kilometres down the Okavango River and spreads through the Delta from May to August, peaking around July and August, in the middle of the cold, bone-dry winter.
The result is the engine of the whole ecosystem: the Delta holds the most water exactly when the surrounding land is driest. Game concentrates on the flood edges, boat safaris hit their prime, and the dry-season months become the best of the year. Most guides that tell you the Okavango 'floods in the rainy season' have it exactly backwards, and every seasonal recommendation built on that error inverts with it.
Motorboats run year-round from the permanent lagoons around Xakanaxa, Third Bridge and Mboma, but they are best from May to September when the flood is in; from October to December falling water levels limit the routes. Mokoro depends entirely on local water level rather than the calendar: broadly May to September in the Delta core, from Mboma Boat Station inside the reserve.
Booking lead times follow the water. For the May to August peak, reserve campsites and camps 9 to 12 months ahead; shoulder and green season need more like 4 to 6 months. The four public campsites inside the reserve routinely sell out 6 to 8 months ahead for June to October.
