Best Time to Go on Safari in Kenya and Tanzania: A Month-by-Month Guide
The best time for a safari in Kenya and Tanzania is June to October, when the dry weather thins the bush, animals gather at rivers and waterholes, and the Great Migration reaches the Maasai Mara. But “best” depends on what you want to see and what you want to spend. January and February are excellent for predators and newborn wildebeest, and the green months of November and April offer better value than most people expect.
Here’s how the year breaks down.
The two safari seasons in East Africa
East Africa has two dry seasons and two rainy ones. The long rains fall from March to May, and the short rains arrive in November and December. The dry seasons are June to October and January to February.
Rain matters because it decides where the animals are. Grass follows water, herds follow grass, and predators follow the herds. If you understand the rain, you can predict most of what you’ll see.
Month-by-month at a glance
| Month | Conditions | Best for |
|---|---|---|
| January | Hot, mostly dry | Calving season in southern Serengeti, big cats |
| February | Hot, dry | Peak calving, predator action at Ndutu |
| March | Rains begin | Quiet parks, green landscapes, lower rates |
| April | Heaviest rain | Lowest prices, birdlife (some camps close) |
| May | Rains ease | Value travel, fewer vehicles |
| June | Dry, cool mornings | Migration moving through the Western Corridor |
| July | Dry | Mara River crossings begin |
| August | Dry | Peak crossings, best overall wildlife density |
| September | Dry | Crossings continue, slightly fewer crowds |
| October | Dry, warming up | Late crossings, Tarangire elephants |
| November | Short rains start | Green scenery, migrant birds, herds heading south |
| December | Showers, then clear | Festive-season safaris, Serengeti return |
January to March: calving season in the Serengeti
Around 8,000 wildebeest calves are born daily in the peak weeks, most of them in the southern Serengeti and Ndutu area. Predators know it. Lions, cheetahs and hyenas hunt openly, and this is the best window to see a kill unfold.
If you’re based in Kenya, these months are also dry and clear in Amboseli, where Kilimanjaro often shows itself at dawn behind the elephant herds. The Maasai Mara holds resident wildlife all year, so a Mara-focused trip works well in this period too.
April and May: the green season
Rain is heavy and some lodges close, especially in April. The trade-off is real: rates drop, the parks are nearly empty, and the land turns bright green. Photographers like the dramatic skies.
Roads in some areas get muddy, so choose camps with good access and an experienced driver-guide. If your dates are flexible and your budget isn’t, this is where the value is.
June to October: peak safari season
This is the headline window. The grass dries, the bush opens up, and animals concentrate near water, which makes game viewing easier and more predictable.
The migration drives the timing. In June, the herds usually move through the Western Corridor and the Grumeti River in Tanzania. From about July, they push north into the Maasai Mara, and the Mara River crossings run through September and often into October. August is the safest bet for dramatic crossings, though no one can promise a specific day. The herds follow the rain, not a calendar. Our guide to the Great Wildebeest Migration explains how the route works.
Tarangire National Park in Tanzania also peaks from June to October, when elephants gather along the river in large numbers.
Expect higher rates and busier camps. Book Mara and Serengeti lodges six to nine months ahead for July to September.
November and December: short rains and a second green season
The rains come as short afternoon showers, not all-day downpours. Mornings are often clear, the landscape recovers fast, and migratory birds arrive from Europe and Asia, which makes this a good time for birders. The herds start moving back south into the Serengeti.
Christmas and New Year weeks are the exception. Prices jump and the best camps fill early, so reserve well ahead if you’re travelling then.
Which country is better at which time?
Kenya works well all year, and the Maasai Mara delivers in most months. Tanzania’s northern circuit (Serengeti, Ngorongoro Crater, Tarangire and Lake Manyara) is strongest from June to October and again from January to March, when the herds sit in the south. Ngorongoro Crater is reliable year-round because its wildlife is resident.
If you can’t decide between them, read The Truth About Kenya vs. Tanzania. Or combine both on one trip: Mara for the crossings, then the Serengeti and Ngorongoro.
How to pick your dates
If crossings are your priority, go in August and accept the higher cost. If you want calving and predators, go in February. If budget matters most, choose April, May or November. If you’re travelling with children or on your first safari, July to October gives the most reliable sightings with the least effort.

Frequently asked questions
What is the cheapest time to go on safari in Kenya and Tanzania?
April, May and early November. Many lodges drop their rates in the rainy months, and parks are far less crowded.
When is the Great Migration in the Maasai Mara?
Herds usually arrive from July and stay until October, with the Mara River crossings peaking in August and September. Timing shifts each year with the rains.
Is it safe to go on safari during the rainy season?
Yes. Safaris run all year. Rain mostly means muddy tracks and some closed camps, so a good operator will adjust the route.
Can I see the Big Five outside peak season?
Yes. The Big Five live in the parks year-round. Dry months make them easier to spot because the vegetation is thinner. See our Big Five guide for Kenya.
How many days do I need?
Three days is enough for the Maasai Mara alone. Plan seven to ten days if you’re combining Kenya and Tanzania.
