Key takeaways

• Calving happens on the southern short-grass plains, not in the central or northern Serengeti where the river crossings take place later in the year.
• Ndutu lies inside the Ngorongoro Conservation Area, on the edge of the southern Serengeti plains, so two different authorities and fee systems are involved.
• Official sources put the herds around Ndutu from the end of December until April, with births concentrated between January and March.
• It is the rainy season. Expect green plains, dramatic skies, some muddy tracks and the need for a four-wheel-drive vehicle.
• Predators follow the herds, but births and hunts are a matter of luck and patience, never a scheduled event.

What is the Serengeti calving season?

The Serengeti calving season is the short period each year when the migrating wildebeest give birth on the southern plains. Tanzania National Parks (TANAPA) describes it as a time when over half a million wildebeest give birth within just a few weeks, with thousands of calves born every day at the peak.

It is one stage of the same year-round movement that produces the river crossings further north in the dry season. TANAPA’s Serengeti National Park page puts the migration at more than 1.5 million wildebeest, zebras and accompanying predators.

Why the births are bunched together

Giving birth at the same time is a survival strategy. TANAPA notes that calving in such numbers overwhelms predators such as lions, hyenas and cheetahs: some calves are taken, but the sheer numbers mean most survive.

When is the Serengeti calving season?

Plan for January to March, with February the month most itineraries are built around. The official sources differ slightly, which is a fair reflection of how the season behaves.

• TANAPA gives January to February as the calving season in its Serengeti visitor information, and describes the event more broadly as unfolding between January and March.
• The Ngorongoro Conservation Area Authority (NCAA) says the herds begin to arrive at Ndutu from the north at the end of December and stay until April, when they start moving north again.
• The NCAA’s frequently asked questions name late February and March as the best time to see the wildebeest migration on the short-grass plains.

Why the dates move

The herds follow fresh grass, and fresh grass follows rain. If the short rains arrive late or the plains dry out, the herds shift, sometimes within days. Treat any calendar, including the one below, as a guide to what is typical and not as a timetable.

Where does the wildebeest calving happen: Ndutu or the southern Serengeti?

Both, because they are the same stretch of plains under two authorities. TANAPA names the southern Serengeti, especially the Ndutu area and the surrounding short-grass plains, as the heart of the calving season.

The NCAA’s Ndutu Plains page places Ndutu inside the Ngorongoro Conservation Area, on the outskirts of the southern Serengeti plains. It describes the area as a calving ground for the migration, with Lake Ndutu and the soda lake Masek, marshes and woodland nearby.

What this means for planning

• Two fee systems. Serengeti National Park is run by TANAPA and the Ngorongoro Conservation Area by the NCAA. A stay at Ndutu and game drives across the boundary can involve both. Fees change, so we do not quote them here. Check the current tariffs on each authority’s website.
• Location of your camp matters. A camp in the central Serengeti is a long drive from the calving grounds. For this season, stay in or near the Ndutu and southern plains area for at least part of the trip.
• The herds are mobile. They move between the conservation area and the national park as grazing changes.

For how this fits the wider loop, see our page on the wildebeest migration safari.

What can you expect to see month by month?

Expect large herds spread across open plains, many young animals and regular predator activity, with the detail changing from month to month. The table is a summary of typical conditions based on the official descriptions above.

Predators

The NCAA lists lion, cheetah, leopard and hyena among the animals of the Ndutu area, along with smaller hunters such as bat-eared fox and jackal.

A word on expectations. Seeing a birth or a hunt takes time in the right place and a measure of luck. A responsible guide keeps the vehicle back so that mothers, calves and hunting cats are not disturbed.

What is the weather like on a Tanzania safari in February?

February falls in the wet half of the year, but it is usually a green and pleasant time on the southern plains, not a washout. The NCAA describes November to April as the rainy season, when wildebeest breed and predators gather.

• Showers. Rain often comes in bursts with clear spells between, which gives photographers strong skies.
• Tracks. The NCAA advises a four-wheel-drive vehicle in the rainy season to avoid getting stuck in muddy areas.
• Packing. A light waterproof, a warm layer for early mornings and a dust-and-rain cover for cameras.

How do you get to the calving grounds, and how many days do you need?

Most visitors reach the southern plains by road from Arusha through the Ngorongoro Conservation Area, or by light aircraft to an airstrip in the area. TANAPA lists Kilimanjaro and Arusha as the nearest airports for the Serengeti.

From Nairobi, the usual plan is to travel to Arusha first and start the safari there.

Suggested length

• Minimum. Two nights in the Ndutu or southern plains area. One night leaves almost no margin if the herds have shifted.
• Better. Three nights on the plains plus the Ngorongoro Crater, which you pass on the way.
• Full circuit. Add Tarangire at the start for elephants and baobabs. Our Tanzania northern circuit guide sets out the usual order of parks.

If you are still choosing between countries, our comparison of the Serengeti and the Masai Mara explains which side suits which month. From January to March the herds are in Tanzania, not Kenya.

Is calving season better than river-crossing season?

Neither is better. They are different experiences at opposite ends of the ecosystem and the calendar.

• Calving season is about wide plains, new life and predators, in green-season light. TANAPA gives January to February.
• The dry-season migration is about dense columns and river crossings. TANAPA gives June to October.

Frequently asked questions

What is the best month for the Serengeti calving season?

February is the month most trips are planned around. Tanzania National Parks gives January to February as calving season, and the Ngorongoro Conservation Area Authority names late February and March as the best time around Ndutu. The exact timing depends on the rains each year.

Is Ndutu in the Serengeti or in Ngorongoro?

Ndutu is inside the Ngorongoro Conservation Area, on the outskirts of the southern Serengeti plains. The herds move freely between the conservation area and Serengeti National Park, so a calving season safari often involves both authorities.

Will I definitely see a wildebeest being born?

No one can promise that. Thousands of calves are born on the plains during the season, so the chances are fair if you spend several days in the right area, but births happen quickly and the herds move with the rain.

Is February a good time for a Tanzania safari?

Yes, if the southern Serengeti and Ndutu are part of the plan. It is the rainy season, so expect green plains, showers and some muddy tracks, along with large herds, young animals and active predators.

How many days do I need for a calving season safari?

Allow at least two nights in the Ndutu or southern plains area, and three if you can. Many travellers add the Ngorongoro Crater and Tarangire to make a trip of five to seven days from Arusha.
