Best Time to Visit Tanzania – Great Migration, Zanzibar and More

Mark Whitman

The best time to visit Tanzania depends on what you want to do. And if you're like me and love adventure (I've climbed Kilimanjaro twice), you're going to want to do it all in this gem of East Africa. 

Here are just a few things that tourists love to do while visiting Tanzania: 

In this article, I'll give you the low-down on how to choose the best time (and weather) before travelling to Tanzania for these awesome adventures and more.

Let's crack on!

The Best Time to Visit Tanzania

Tanzania Weather and Temperatures 

Like any activity you do outside your home, it's always a good idea to first check the weather before booking a trip to Tanzania. This will give you a better idea of when to travel and what activities you can do during your stay. 

The hottest and most humid period stretches between November and February (25–31°C), whilst the coolest time occurs between May and August (15–20°C).

In the highlands, temperatures range between 10 and 20°C during cold and hot seasons. Thankfully, in the rest of the country, the temperatures rarely fall below 20°C.

The Best Time for Popular Tanzanian Tourist Activities

If you like wildlife, exhilarating hiking trails, or a leisurely beach vacation, you'll want to pick the best time for visiting Tanzania.

As a rule of thumb, clear and sunny skies reign supreme between June and October, while tropical downpours are the norm from March till May.

Here are some quick hacks for choosing the best time to visit Tanzania for activities loved most by tourists:

  • The best time for a classic safari experience in Tanzania is from June till August.
  • The best time to visit Tanzania to see the Great Wildebeest Migration is between July and September.
  • The best time for trekking and chimpanzee tracking in Tanzania (Gombe Stream National Park and Mahale Mountains National Park) is between May and October. 
  • The best time to climb Kilimanjaro is from July till October and from December till February.
  • The best time for a Zanzibar holiday is between June and October.
  • The best time to see aquatic animals is all year. 

Now, let's go more in-depth about the best time to visit Tanzania for these epic activities!



One can easily be overwhelmed by the vastness of Tanzania and the myriad of wildlife experiences the country offers, especially when choosing the best time to visit Safari Country. But don't worry - you're in good hands! 

Best Time for a Classic Safari

To make it easier to decide when to go, and where to explore the different sights and sounds on your classic safari, Tanzania is roughly divided into three areas:

  • Northern Parks
  • Southern Parks
  • Western Parks

The Northern Parks are SerengetiNgorongoro CraterLake Manyara, and Arusha. The wonders of these parks can be explored throughout the year. The weather is pleasant with moderate temperatures between June and October, making it the high season.

The Southern Parks are Selous and Ruaha Mild temperatures and dry weather are prevalent from the end of May till around December, making it a good time to visit. 

The Western Parks are Gombe, Mahale Mountains, and Katavi. Chimpanzee trekking in Gombe and Mahale is best experienced during the dry season, between July and October. March and April are exceptionally wet.

Tanzania is fondly nicknamed a 'Safari Country' due to its 17 national parks and 7 game reserves. 

Tanzania offers ample opportunity and time for a classic safari experience with its numerous national parks and game reserves. Wildlife hotspots include the Serengeti National Park, Ngorongoro Crater, Lake Manyara National Park, Selous National Park and Gombe Stream National Park.

The seasons in Tanzania are not distinguished by winter and summer, only dry and wet. The long rains occur between March and May while the short rains last from October till late December. Travellers should therefore plan their classic safari accordingly as trails in some national parks are impassable during this time. 

The best time for a classic safari experience in Tanzania is from June till August, towards the end of the long rains. Temperatures are moderate during the day and at night. 

Hot and humid temperatures reaching the mid-30C are prevalent during January and February. Travellers visiting Tanzania at this time will, however, have the opportunity to witness huge herds of animals, especially in the Serengeti during the Great Migration. 


The Great Wildebeest Migration

Driven and dictated by the rain, the Great Wildebeest Migration is regarded as one of the greatest natural phenomena in the world with almost 2 million wildebeest and zebra tempting fate in search of greener pastures each year.

Best Time to Visit Tanzania for the Wildebeest Migration

The best time to visit Tanzania to bear witness to the migration is between July and September. This is when the herds of wildebeest make their way from inside the Serengeti National Park over the Grumeti River, on towards the Mara River and into Kenya and the plains of the Maasai Mara.

Timeline of the Great Migration

  • June-July: The animals begin to move en masse from the central to the northern and western parts of the Serengeti.
  • August-September: It is time for the much-anticipated crossing of the Mara River into Kenya in search of greener pastures. 
  • October-December: The animals have had their fill and are starting to move back towards the Serengeti. 
  • February-June: Following the onset of the Tanzania wet season, thousands of new calves are born every day. 

Below is a detailed spreadsheet to give you more insight into this magical time for the Serengeti wildebeest:

I remember the first time I visited Tanzania and came face to face with a chimpanzee, the closest animal relative to humans. It was a humbling and life-changing experience to say the least. Getting to these out-of-the-way regions of Tanzania won't be easy or cheap but spending time with these beautiful creatures is an opportunity of a lifetime and well worth the extra effort.

Best Time for Chimpanzee Trekking

The best time for chimpanzee trekking in Western Tanzania coincides with the beginning of the dry season.

The best chance of coming face to face with these remarkable primates in Mahale and Gombe is between May and October. Trekking is undertaken without too much effort as the chimpanzees frequent the lower slopes. Sunshine reigns supreme with little to no rain. This also means fewer mosquitoes. 

During the wet season, between November and April, chimpanzee trekking becomes arduous as the trails are slippery. It is extremely hot and humid. Some accommodation providers close.


Mount Kilimanjaro

Mount Kilimanjaro towers over the landscape as the highest point on the continent at 5,895 metres. Lying in the Kilimanjaro National Park, the mountain offers a unique climbing experience. The vegetation and the weather vary depending on the elevation. 

Best time to Climb Kilimanjaro

The best time to visit Tanzania and get to the Roof of Africa coincides with the drier months and the periods between July and October, and December and February. An exhilarating hiking experience in icy conditions can then easily be combined with the front row seat to the Great Wildebeest Migration.

It can, however, get crowded on the way to the summit during December. To encounter fewer climbers, consider April and May as an alternative, even though it is the wet season. The weather is unpredictable and reports of snow blizzards during the dry season have been recorded. 

Best time to visit Tanzania


The pristine beaches of Zanzibar are the ideal spot for escaping the concrete jungle, and an even better place to finish a once in a lifetime trip to Africa.

Best Time to Enjoy Zanzibar Beaches

The best time to visit Tanzania and make the most of your time in Zanzibar is between June and October. Clear and sunny weather is a given and ideal for soaking up the sun.

The Zanzibar Archipelago consists of many small islands and two large ones – Zanzibar or Unguja and Pemba Island. Found near the equator, the islands are warm throughout the year with respite coming from the refreshing Indian Ocean breeze. 

Sun-seekers should avoid the rainy season from March till May. Downpours can also be expected in November and December. 

For diving and scuba enthusiasts, dipping beneath the surface is particularly good between June and October on the north coast, and between November and March on the south coast. The average water temperature throughout the year is around 27C (81F).


Sea Animals

Safaris aren't the only activity in Tanzania where you can see unique wildlife. Travelling further along the coast towards the lesser known national parks like Burigo Chato, Rubondo Islands, Saadani and Saanane will give you a rare opportunity to see Tanzania's greatest aquatic species in their natural habitats. 

When to see various aquatic species of animals

Below is a short break down off all the best times to visit Tanzania's wettest wildlife wonders: 

  • All year round: Dolphins, whitetip reef sharks, hawksbill turtles
  • June to March: Seahorses, blacktip reef sharks, eagle rays
  • July to October: Humpback whales 
  • October to February: Whale sharks
  • November to February: Hammerhead sharks
  • December to April: Manta rays


This article was just a small taste of the best times to visit Tanzania and all the wonderful things you can do and see in this amazing country. I hope my insights help you catch the next flight out to the undisputed jewel of East Africa.

  1. Hi Mark! I really like your blog posts, they're both insightful and well-written. I'd like to ask for your recommendations on local Kenya tour operators, especially those that focus on responsible tourism. Meanwhile, we're looking to plan a trip in late August 2023, primarily to view the big 5 and other animals in the Masai Mara region. Do you think there are better ways to do this, maybe put it off until May of the next year and visit Tanzania and Serengeti instead? What would you suggest?
