The contrarian season
Moremi in the rains: a season with two clocks
From November the storms arrive, the bush turns green and the lodges cut their rates, and none of it has anything to do with the Okavango flood, which is still months away in Angola. Understand that double clock and the green season stops being confusing. This page makes the honest case for it.
If you only want the answer
Yes, go, if you are the right visitor. November to March gives you Moremi at its greenest, cheapest and emptiest: the birding at its annual peak, newborn impala in their thousands, storm light over the floodplains and lodge rates at roughly half of peak. The catch is the double clock: local rain falls now, but the Okavango flood arrives months later and peaks in July and August, so the green season is high grass over low water. Tracks get waterlogged, the wooden bridges become a question mark, and the reserve occasionally closes outright after heavy rain. If boating, mokoro or concentrated big game is the point of your trip, wait for the flood months instead.
Two clocks, five months apart
Two separate water events run Moremi, and they are about five months out of phase. The first clock is local rain: storms build from November, peak in January and February, and taper away through March. The second clock is the flood: rain that fell in the Angolan highlands between December and March travels roughly 1,200 kilometres down the Okavango River, reaches the Delta from around April, spreads from May to August and peaks in July and August, in the middle of the cold, bone-dry winter.
So the green season is the rain clock without the flood clock. When you visit in December you get thunderstorms over channels that are near their lowest annual levels, because last year's flood has drained away and this year's is still crossing Angola and Namibia. Anyone who books the rains expecting high water has it exactly backwards: the Delta holds the most water when the surrounding land is driest, and the least when the sky is busiest. Every green-season decision on this page follows from that inversion.
What the rains actually do
November opens with relief: the first storms break October's heat, which is the hottest of the year at an average maximum of 36.5°C. From there the rain builds steadily to its January peak before easing through March. The bush thickens fast, the game that spent the winter pinned to the flood edges disperses across the whole map, and the black-cotton and clay sections of track hold water for days after a storm.
The month-by-month numbers below are thirty-year climate normals, not brochure optimism. Read the rain-days column as the honest one: in January you should plan around rain on two days out of three, usually as afternoon storms rather than all-day drizzle.
| Month | Average max | Rainfall | Rain days | Character |
|---|---|---|---|---|
| November | 33.2°C | 66 mm | 12 | First storms break the heat; game still good but dispersing |
| December | 31.6°C | 118 mm | 17 | The green season proper: storms, newborns, deteriorating roads |
| January | 30.5°C | 161 mm | 21 | Wettest month of the year; thick bush, scattered game |
| February | 29.7°C | 117 mm | 16 | Still heavy; waterlogged tracks and possible closures |
| March | 30.8°C | 64 mm | 10 | Rains taper, roads recover, the first floodwater nears |

Which tracks and crossings suffer
Moremi's log bridges are the choke points. Vehicles must be under 5 tonnes to cross, First and Second Bridge are normally passable if slightly alarming, and Third Bridge, between the campsite and Xakanaxa, is the fragile one: when it is out, the direct route closes and the detour via South Gate takes 5.5 to 6 hours. In the rains, assume any bridge can be a question mark and ask before you rely on one.
The tracks themselves split by soil. The deep Kalahari sand actually drives better slightly damp; it is the clay and floodplain-margin sections that turn greasy and hold standing water, and the delta-edge routes, Xakanaxa to North Gate above all, degrade first. In the wet season the reserve is occasionally closed entirely for a week or two after heavy rain, and early 2026 showed the extreme version: record flooding shut Moremi from about 6 March until 13 April, and as late as May the Third Bridge area remained closed and Khwai to Xakanaxa was inaccessible. Check current status with DWNP or your campsite concessionaire days before you travel, not weeks.
One small green-season gain on the logistics side: gate hours stretch to 05:30 to 19:00 from October to March, against 06:00 to 18:30 in winter, so your legal day is an hour longer exactly when the light is at its most dramatic.
What the green months genuinely offer
The birding is the headline, and it is not a consolation prize. Moremi's list runs past 400 species as the protected core of a Delta with 482 recorded, and the migrants are only here now, from roughly November to March, when everything is calling and breeding at once. Wattled crane, slaty egret and Pel's fishing owl are residents you can find year-round, but the full spectacle, storks and cuckoos and kingfishers in breeding colour, belongs to the rains. If you carry binoculars before a long lens, this is your season.
The first November storms also trigger the impala lambing, and within weeks the floodplain margins are full of newborn antelope and the predators working them. You trade winter's concentrated game on the flood edges for a greener, more scattered kind of drama, harder to find and emptier of vehicles when you do.
Photographers get the third argument: storm cells stacking over open floodplain, washed air, green-on-charcoal light that the dusty winter never produces. Campsites that sell out 6 to 8 months ahead for June to October sit half empty.
And the money is real, at the lodges at least. Elephant Pan drops from $1,045 in the peak to $595 in the green season; Camp Moremi runs $690 low season against $1,290 high; &Beyond Sandibe's 2027 ladder falls from $3,800 in high season to $1,850 between 11 January and 31 March. Roughly half price is the pattern across the board. What does not move is the government's side: park entry stays at P270 per person per day for non-residents all year, every day counts including departure day, and the private concessionaires who run the campsites barely discount either. The green season is a lodge bargain, not a fee bargain.
Who should wait for the flood months
The flood months, May to September, exist for a reason, and some trips simply belong there. Be honest about which trip you are planning.
- Anyone whose Moremi is a water trip. Motorboats from Xakanaxa, Third Bridge and Mboma are at their best from May to September when the flood is in, and mokoro from Mboma Boat Station depends entirely on water level. In the green season the channels are low; the rain does not fix that.
- Wild dog seekers. The packs den from roughly June to August, which is the one window they are anchored to a point on the map instead of ranging across hundreds of square kilometres.
- Big-game-first visitors. July to October concentrates elephant, buffalo and the predators along the Khwai and the lagoons; the rains disperse all of it into thick bush.
- First-time self-drivers. Learn this reserve in the dry months, when a wrong turn costs an afternoon rather than a recovery operation at a flooded crossing.
- Anyone on a fixed schedule. Rain rewrites routes daily, closures happen with little notice, and the 2026 season proved the reserve can shut entirely.
If you do come: the short checklist
- Book a campsite before anything else: a confirmed reservation is required to enter the reserve at all, and the four public campsites are run by private concessionaires, not DWNP.
- Carry pula in cash for the gate: P270 per person per day, P75 for a foreign-registered vehicle as the working figure, charged every day including the day you leave.
- Drive a high-clearance 4x4 with recovery gear, and treat every bridge and water crossing as a decision, not a formality.
- Fuel, food and cash all come from Maun; there is nothing in the reserve beyond a basic shop at Third Bridge.
- Navigate with a paper map plus an offline app; there is no signal in most of the reserve.
- Take malaria advice seriously: northern Botswana's risk is highest in and after the rains, which is exactly when you are going.
