Serengeti month-by-month

When to visit the Serengeti: month-by-month guide

The Serengeti doesn’t have an off-season. It has phases. The wildebeest migration, roughly two million animals moving in a rough clockwise circuit, dictates the rhythm of the entire ecosystem, and each month brings the herds to a different part of the park. Understanding that rhythm, alongside rainfall and temperature patterns, is the fastest way to work out which month suits the safari you actually want.

This guide breaks the year down month by month, covering where the migration typically sits, what the weather does, and what a safari in that period looks like on the ground.

Serengeti seasons at a glance

The Serengeti sits at 1,100 to 2,000 metres above sea level, which keeps temperatures moderate year-round. Rainfall, not temperature, is the variable that shapes a safari here.

Quick answer guide

• Best for the wildebeest calving season: Late January to March

• Best for photography: June to October for dry-season wildlife, or January to March for dramatic calving scenes and lush landscapes

• Best value: April and May, when lower rates and fewer visitors can offer exceptional value despite occasional rain

The Serengeti month by month

January in the Serengeti

January sits in the short dry spell between the short and long rains, so mornings are clear and afternoons can bring a passing shower. Daytime temperatures reach around 28°C, with cooler nights near 16°C. The wildebeest have mostly moved onto the eastern and southern short-grass plains, drawn by the nutrient-rich grass that will support the calving to come. Lions and hyenas begin to gather on the fringes of the herds, anticipating the births. This is a strong month for travellers who want big herds without the crowds of the July to September peak.

February in the Serengeti

February is the heart of calving season. Around 500,000 wildebeest calves are born within a two to three week window, concentrated on the short-grass plains around the Ndutu area and the southern Serengeti. The sheer volume of newborns overwhelms the resident predators, giving individual calves a better chance of survival even as lions, cheetahs and hyenas hunt in full view of visiting vehicles. Rainfall remains relatively light for a wet-season month, and the flat, open terrain of the calving grounds makes for some of the clearest wildlife viewing and photography conditions found anywhere in the Serengeti-Mara ecosystem.

March in the Serengeti

The long rains typically begin in March, and the herds start shifting their attention from calving to mating. Male wildebeest compete fiercely for females during the rut, which runs alongside the herds' gradual northward drift out of the southern plains. Rainfall increases through the month, landscapes turn a deep green, and visitor numbers drop noticeably compared with the earlier calving peak. Roads can be muddy in places, so open-sided vehicles and flexible itineraries help here.

April in the Serengeti

April is the wettest month of the year in the Serengeti, with rain falling on roughly 20 days and accounting for well over 100mm of the month's total. The herds continue their push north and west, moving in long columns through the central Serengeti around the Seronera area and the Moru Kopjes. Rates fall to their lowest point of the year and vehicle numbers thin out considerably. Given the reduced visibility that comes with tall, rain-fed grass, this suits travellers prioritising value and solitude over guaranteed sightings.

May in the Serengeti

May marks the transition out of the long rains. Showers become less frequent as the month progresses, though the landscape remains lush and green well into the following weeks. The herds, calves now strong enough to keep pace, pick up speed as they move through the western corridor towards the Grumeti River. Rates and crowds are still low, making May one of the better-value months for travellers who don't need river-crossing drama.

June in the Serengeti

June signals the start of the dry season proper. Rainfall drops sharply, skies clear, and the bulk of the migration gathers in the western corridor, where the Grumeti River presents the first serious water crossing of the annual cycle. Grumeti crossings are less consistent than the Mara River crossings later in the year, since water levels depend heavily on that season's rains, but the herds' movement through this stretch still produces excellent, less crowded wildlife viewing. Nights turn noticeably cooler, particularly at higher-altitude lodges.

July in the Serengeti

July is when the migration's centre of gravity shifts firmly north. The vanguard of the herd typically reaches the Mara River's southern bank in the second half of the month, with the first crossings into the Mara-Serengeti ecosystem's northern reaches occurring from mid to late July depending on that year's conditions. Skies are reliably clear and dry, days are warm without being uncomfortably hot, and this is the point at which advance booking becomes essential for lodges positioned near the river.

August in the Serengeti

August delivers the migration's most photographed spectacle: large-scale Mara River crossings, with wildebeest and zebra plunging into crocodile-patrolled water in their tens of thousands. This is peak season, both for wildlife activity and for visitor numbers, so vehicle congestion at popular crossing points is a realistic trade-off for the drama on offer. Lodges in the northern Serengeti fill up close to a year in advance for this period. Dry, dust-lit afternoons and cool, clear evenings are typical.

September in the Serengeti

September remains firmly within crossing season, though the balance of the herd has usually shifted further into the Maasai Mara-Serengeti border zone, with river traffic moving in both directions as some groups cross back into Tanzania. Weather stays dry and warm, and demand for northern Serengeti lodges remains high, though marginally lower than August. This is a dependable month for travellers who want crossing potential without committing to the very peak of the season.

October in the Serengeti

By October, the northward push has run its course and the herds begin drifting back south through the Lobo area and the little-visited northern plains. Southbound crossings of the Mara River tend to happen faster and with less prolonged hesitation than the northbound crossings earlier in the year. Vehicle numbers ease noticeably from the September peak, rates soften slightly, and the northern Serengeti and Lobo area offer some of the most rewarding, uncrowded wildlife viewing of the year for travellers with flexible dates.

November in the Serengeti

The short rains typically arrive in November, breaking the dry season and pulling the migration south out of the north and through the central Serengeti and Lobo region. Rainfall is unpredictable in both timing and volume, and can occasionally fail altogether in the drier southeast of the park, but when it does fall it revives the landscape quickly. This is a genuine shoulder-season month, with moderate crowds, greener scenery than the preceding dry months, and herds actively repositioning for the calving grounds.

December in the Serengeti

December sees the migration completing its return to the southern short-grass plains, ready for the calving season that follows in January and February. Rainfall from the short rains tends to ease as the month progresses, though showers remain a possibility. Some years bring early calving activity in late December, giving well-timed December travellers a preview of the following months' predator action. Rates and crowds remain moderate, rising towards the December and January holiday period.

Serengeti timing against the wider northern circuit

The Serengeti rarely stands alone on an itinerary. Most first-time travellers combine it with the Ngorongoro Crater and Tarangire National Park as part of Tanzania's northern circuit, and the timing that suits the Serengeti generally suits the wider route too, since all three sit within the same broad climate zone. For a full breakdown of how these destinations fit together across the year, see our guide to Tanzania's northern safari circuit. Linda Fox, AG Tanzania safari expert, makes the case for starting in Tarangire before heading north: "I love starting a northern Tanzania safari in Tarangire. Diverse habitats, 500+ bird species, elephants in wetlands, lions on termite mounds, and lovebirds in baobabs. A magical start to any Tanzania adventure!"

Travellers weighing up the Serengeti against Kenya's Masai Mara should note that the two parks form a single ecosystem, and the Great Migration simply crosses the border rather than starting afresh. Our broader look at Africa's great wildlife migrations sets the Serengeti-Mara cycle in context alongside other migratory spectacles across the continent.

Where you stay matters as much as when you travel. Infrastructure and lodge density can affect wildlife behaviour even in peak season, a point explored in our piece on why lodge choice matters in the Serengeti. Our safari experts factor this into every itinerary, positioning lodges to balance access to the migration against the pressure that high vehicle density can place on wildlife.

Families weighing up when to travel should also read our guide to Africa's best family safari destinations, which covers age recommendations and seasonal considerations for travelling with children in the Serengeti and beyond.

Beyond the Great Migration

The Serengeti's resident wildlife does not disappear when the migration moves elsewhere. Wild dog sightings, once rare in the park, have increased in recent years, and our feature on wild dogs returning to the Serengeti is worth reading regardless of which month you travel. Walking safaris also run year-round in parts of the ecosystem, offering a different pace entirely, as described in our account of a Serengeti walking safari.
