Best Time to Visit Tanzania for a Safari

It’s the question we get asked before almost anything else: when should we actually go? The honest answer is that there isn’t one single «best» month — there’s a best time for whatever you specifically want out of the trip. Here’s how the year actually breaks down.

Dry season (June to October): the most popular, for good reason

This is high season, and it earns the label. Vegetation thins out and wildlife concentrates around the few remaining water sources, which makes spotting animals considerably easier. Clear skies most days, good road conditions, and the best odds of seeing the Big Five in a short trip.

It’s also, unsurprisingly, when the most other travellers are around, and lodge and camp rates run highest — worth booking several months out, especially for the smaller, best-located camps in the central Serengeti.

Green season (November to May): fewer people, a different landscape

The short rains in November and December transform the savannah: everything turns green, migratory birds arrive from Europe, and most herbivores give birth. Tourist numbers drop noticeably, rates come down, and many guides consider the light this time of year the best for photography.

January and February: calving season in the southern Serengeti

Not widely advertised, but well known among repeat safari travellers: for a few weeks in January and February, hundreds of thousands of wildebeest give birth in near-unison on the plains around Ndutu and the southern Serengeti. The concentration of newborns draws every predator in the area — it’s one of the best windows all year for lion and cheetah action, with far fewer people around than in dry season.

March to May: the long rains

The quietest, most affordable stretch of the year. Some camps close or drop their rates significantly, and remote tracks can get harder going after heavy rain — though the core circuit (Tarangire, Serengeti, Ngorongoro) stays fully accessible. In exchange: dramatic skies, green landscapes most photos never show, and the best prices of the year.

What about the Great Migration?

The Great Migration is a year-round, circular movement of over two million wildebeest and zebra, not a single event tied to one month. Broadly: the herds calve in the southern Serengeti from December to March, move north through the central Serengeti in April and May, and reach the Mara River crossings in the north between roughly June and October. River crossings themselves can’t be predicted on a fixed date — they depend on that year’s rainfall. For the full month-by-month breakdown by area of the park, see our Serengeti safari guide.

Choosing based on what matters to you

• First safari, want the Big Five without complications: dry season (June–October).
• Honeymoon on a tighter budget: March–May or November, same parks, better rates.
• Want fewer people and dramatic photography light: green season, especially January–February.
• Travelling with kids: dry season, for easier roads and less rain to plan around.
• Chasing a river crossing specifically: late June through September, with a guide who tracks the herd’s real movement that season, and realistic expectations — see our note above on why nothing here can be guaranteed.

Where this fits into your itinerary

Season affects more than wildlife odds — it also shapes which parks make sense together. The Ngorongoro Crater is a strong choice year-round thanks to its self-contained ecosystem, which makes it a reliable pairing whatever month you're travelling. Once you have a sense of timing, our safari packages show how these parks combine into routes by length.
