Serengeti in May: Cheapest Month, Outstanding Wildlife

May is the cheapest month to safari in the Serengeti. It is also one of the most underrated. The combination of green season pricing, lush landscapes, emptier parks, and the beginning of the Western Corridor migration creates a month that experienced safari travellers return to repeatedly — while first-timers scroll past it looking for July availability.

The long rains are at their tail end in May, typically easing during the second and third weeks of the month. By late May, the days are becoming clearer and longer, the mud is drying, and the transition to dry season is underway. A late May safari can feel almost like early June — with green season prices.

What the Migration is Doing in May

May is when the Western Corridor migration becomes visible and dramatic. The wildebeest herds that crossed the central Serengeti in April are now moving through the long western arm of the park, heading toward the Grumeti River. Large concentrations of wildebeest are often found along the western corridor roads — not the Seronera Valley, but the Ndabaka Gate area and the roads toward Kirawira.

The Grumeti River crossings, which are the Serengeti's first major river crossings of the year, typically begin in late May or early June. For travellers who want river crossings without the August crowds and prices, a late May western corridor positioning can produce excellent crossing opportunities with a fraction of the vehicles. Grumeti crossings are smaller in scale than the Mara, but the experience — vehicle alone at a crossing point with a river full of crocodiles — can be just as intense.

The southern Serengeti, where calving happened in January and February, is largely empty of migration herds by May. The resident wildlife remains — permanent lions, leopards, cheetahs — but the open-plains wildebeest spectacle has moved on. Central Serengeti continues to deliver consistent big cat sightings year-round.

Weather in May

Early May can still bring afternoon showers, particularly in the first two weeks. By mid-May, the rain becomes more intermittent. Late May in most years sees mostly dry days with occasional brief showers. The landscape is still green and lush — the dry season brown that characterises July does not arrive until June and July.

Mornings in May are almost always clear. The combination of clean air after the rains, soft morning light, and green landscapes creates genuinely beautiful conditions that no amount of dry season photography can replicate. The light in May is different — softer, more diffuse, with richer greens and more atmospheric depth than the harsh bright skies of peak season.

Wildlife in May

May wildlife is excellent. The green season does not diminish wildlife — it redistributes it. Animals that concentrated near permanent water sources during the dry season now have access to water across the park, which means more dispersed sightings but also more unexpected encounters in unexpected places.

Elephants are frequently encountered in May across areas of the park where they are absent in the dry season. The Seronera Valley lions are active and, with calves born earlier in the year now approaching three months old, often seen in family groups. Wild dogs, which are more reliably sighted during the rainy season than the dry, have their pup-rearing season peaking in May — a genuinely rare sighting that May visitors sometimes encounter by luck and positioning.

Birdlife in May is extraordinary. The combination of resident Serengeti birds and intra-African migrants produces species counts that peak in the rainy season months. A single May game drive in the Seronera Valley can produce 50–80 bird species. For travellers with a birding interest, May is arguably the best month of the Serengeti year.

Prices in May

May is, along with April, the cheapest month to visit the Serengeti. Accommodation prices are typically 30–40% below peak season. A mid-range tented lodge that costs $364–$416 per person per night in August may be available at $229–$270 in May. Over a 7-day trip, this saving can reach $936–$1,456 per person — enough to add Zanzibar to the itinerary without increasing your total budget.

Some bush camps and seasonal tented camps remain closed until June. Safaris Tanzania maintains up-to-date information on which properties are open in May and books clients into accommodation that is confirmed operational for their dates. This sounds obvious but it is a genuine risk when booking through agents who do not have current camp status information.

Practical Advice for May

A May itinerary that wants both central Serengeti wildlife and the possibility of early Grumeti crossings should allocate two nights in Seronera and two to three nights in the western corridor. This positioning covers the park's two most productive zones for May conditions.

Packing for May still requires a light rain jacket. Most days will not need it. But the afternoon shower that sends you back to camp at 4pm is more pleasant if you are not soaked. A fleece for early mornings, sun protection for midday, rain layer for afternoons — the same kit that works for April applies to May.

The key practical advantage of booking May with Safaris Tanzania rather than through an agent: we know which camps are actually open, which roads are currently accessible, and where the wildlife is concentrated. We adjust itineraries based on real-time ground information. A May safari booked through a European agent is based on last year's conditions and generic advice. Ours is based on what Kassim's guides are reporting from the park this week.
