Tanzania is a year-round safari destination. Wildlife is present in every month, in every park. But the experience you have β the landscapes, the weather, the movement of the Great Migration, the crowds around you, and the price you pay β varies enormously from month to month. Understanding these differences is how you design the right trip for you.
At Bobby Safaris, we have been designing exclusive Tanzania safaris since 1978. Our clients span first-time visitors to seasoned Africa hands. In that time, we have learned one consistent truth: the best time to visit Tanzania is not a single answer. It is a personal one.
How to Use This Guide
Each month below is rated for wildlife, weather, and value. No month is simply "bad." The question is which combination of factors is right for your priorities, your schedule, and your tolerance for trade-offs. We have been honest about the drawbacks of each month β and the genuine strengths.
Tanzania's Two Safari Seasons
Tanzania's safari calendar divides into two broad seasons, each with distinct characteristics:
- Dry season (June to October): The iconic safari experience. Wildlife concentrates around water sources, making game viewing predictable and dramatic. Skies are clear, roads are in excellent condition, and all parks and camps are fully operational. This is the season of the Great Migration river crossings, the golden savanna, and the highest prices.
- Green season (November to May): The landscapes transform. Vivid emerald grass, dramatic afternoon thunderclouds, and newborn wildlife define this period. Visitor numbers drop dramatically β sometimes 80% fewer than peak season β and prices follow. The trade-offs are afternoon rain (manageable) and slightly more dispersed wildlife (by design, more intimate).
Neither season is objectively better. They are different experiences, both excellent.
Month by Month: The Full Picture
January
ExceptionalPeak calving season
Weather
Dry and sunny. Warm days, cool mornings.
Wildlife
Wildebeest calving in Southern Serengeti and Ndutu. Predator action exceptional.
Crowds
Moderate β growing towards peak.
The wildebeest calving season is one of the most extraordinary wildlife spectacles on Earth. Approximately 500,000 calves are born within a four to six week window, and the predator concentration that follows β lions, cheetahs, hyenas β is extraordinary. This is peak green season: lush landscapes, empty of other travellers, exceptional for photography.
February
ExceptionalCalving continues
Weather
Dry. Warm to hot. settled weather.
Wildlife
Calving continues in Southern Serengeti. Breeding birdlife in full plumage.
Crowds
Moderate.
February maintains the calving season conditions, with slightly higher numbers of visitors as word spreads about the Ndutu spectacle. The landscape remains green and vivid. Breeding migrant birds from Europe and Asia add exceptional birdlife to any game drive. One of the finest months overall.
March
Good valueShoulder month
Weather
Transitional β first rains may begin late in the month.
Wildlife
Herds begin to move north. Wildlife still concentrated and accessible.
Crowds
Lower β the peak season crowd has not yet arrived.
March sits between the green season and the dry season, offering a compelling combination of reduced crowds, lower prices, and excellent wildlife. The first rains typically arrive late in the month, bringing the first flush of green to the landscape. Excellent month for photographers and those prioritising value.
April
Best valueLong rains peak
Weather
Rainy. Afternoon thunderstorms, sometimes sustained. Humid.
Wildlife
Wildlife remains present. Animals distributed differently β more dispersed.
Crowds
Very low β lowest of the year.
April is the quietest month in Tanzania and the lowest-priced. Some secondary roads become difficult, and a small number of camps close for annual maintenance. Wildlife does not disappear β it simply becomes more dispersed across a greener landscape. For flexible travellers who prioritse value and solitude over convenience, April is a hidden gem.
May
Good valueLong rains easing
Weather
Rain decreasing through the month. Lush, green landscape.
Wildlife
The Serengeti and Ngorongoro remain fully accessible and excellent.
Crowds
Low.
May marks the transition out of the long rainy season. The landscape is at its most lush and beautiful, roads are generally fine with a capable vehicle, and prices remain at green-season lows. Wildlife is excellent β the migration herds are beginning to move north. This is an excellent month for experienced travellers who appreciate the quiet, green Tanzania.
June
GoodDry season begins
Weather
RainθΆζ₯θΆε°. Pleasant temperatures. Clear skies.
Wildlife
Migration herds moving north through the Serengeti Western Corridor.
Crowds
Increasing.
June is a transitional month that offers the best of both worlds β the dry season is beginning (better roads, concentrated wildlife), but prices have not yet reached their peak. The migration herds are moving north through the western corridor. The landscape is still partially green from the rains. A solid choice for those who want dry-season conditions without peak-season prices.
July
IconicPeak dry season
Weather
Dry and sunny. Pleasant temperatures. Cool mornings.
Wildlife
River crossings begin on the Grumeti and Mara Rivers.
Crowds
High β peak season begins.
July marks the beginning of the iconic dry season. River crossings β where the migration herds cross the Grumeti and then the Mara River β begin in earnest. Wildlife concentrates rapidly as water sources shrink. This is the Tanzania that appears in every documentary and photography book. Prices are at their highest. Crowds at popular sighting points are significant. But the wildlife spectacle is exactly what you came for.
August
IconicRiver crossings
Weather
Dry and sunny. Pleasant. Cool mornings and evenings.
Wildlife
Mara River crossings β the dramatic climax of the migration.
Crowds
Very high.
August is the month of the Mara River crossings β the most dramatic and celebrated moments of the Great Migration. The visual spectacle of thousands of wildebeest in a mass of movement, crocodiles waiting, and predators following is unparalleled. The Ngorongoro Crater and central Serengeti are also at their peak wildlife density. This is the most popular month, and you should plan well in advance.
September
IconicCrossings continue
Weather
Dry. Warm days, cool nights.
Wildlife
Mara River crossings continue. Migration enters KenyaMasai Mara.
Crowds
Very high.
September continues the dramatic crossing season. The migration is split between the Tanzania side (northern Serengeti) and Kenya's Masai Mara. If you are based in Tanzania's Lamai Wedge or northern Serengeti, crossings remain spectacular. This is high peak season β book 12 months ahead for the best camps.
October
GoodShoulder β migration returning
Weather
Dry. Temperatures rising slightly.
Wildlife
Wildebeest begin moving south again into Tanzania's northern Serengeti.
Crowds
High β but beginning to ease.
October sees the migration herds beginning to return south from Kenya into Tanzania's northern Serengeti. The Lamai Wedge and eastern Lamai areas offer excellent crossings as the herds re-enter Tanzania. Crowds are still significant, but beginning to thin as the school holidays end. Prices ease slightly from September levels.
November
Good valueShort rains begin
Weather
Transitional β first short rains. Often afternoon showers, clearing quickly.
Wildlife
Herds moving south. Landscape turning green.
Crowds
Moderate and falling.
November is one of the finest travel windows in Tanzania. The short rains arrive β typically in afternoon bursts that clear quickly, leaving the landscape fresh and vivid. The migration is moving south through the eastern and southern Serengeti. Crowds are significantly lower than peak season. Prices are dropping. This is our top recommendation for first-time visitors who want a balance of excellent wildlife, good weather, and manageable crowds.
December
Good with caveatsFestive season
Weather
Short rains. Warm. Often sunny between showers.
Wildlife
Wildebeest herds in Southern and Eastern Serengeti.
Crowds
High during the festive period β late December in particular.
December combines the short rains' green landscapes with the beginning of the wildebeest calving cycle's return. The Serengeti and Ndutu are receiving the first migration herds. The festive period β particularly late December β sees a significant increase in visitors and peak-season pricing. Early December, before the school holidays fully peak, can be an excellent time.
The Great Migration: A Year-Long Journey
The Great Migration is the continuous movement of approximately 1.5 million wildebeest β plus hundreds of thousands of zebras and gazelles β across a 1,500-kilometre circuit through Tanzania and Kenya. It is not a one-time event you either catch or miss. It is a perpetual movement, and wildlife is always somewhere along the route.
In Tanzania specifically, the cycle looks like this:
- January to March: Calving season in the Southern Serengeti and Ndutu region. Approximately 500,000 calves born within four to six weeks. Predator action is exceptional.
- April to June: Herds move north through the central and western Serengeti, crossing the Grumeti River in dramatic fashion.
- July to October: The Mara River crossings β the most dramatic and celebrated moments of the migration. Peak dry season wildlife concentration.
- November to December: Herds move south and east, returning through the northern and eastern Serengeti, often crossing back into Tanzania from Kenya's Masai Mara.
No matter when you visit between June and March, it is possible to time your trip to catch some phase of the migration in Tanzania. July through October offers the most dramatic and iconic moments. January through March offers the most intimate and emotionally powerful phase β the calving season β with dramatically fewer other vehicles.
Our Honest Assessment
The "best" time to visit Tanzania depends entirely on what you want from the experience. We have had clients weep at the calving season β watching a newborn wildebeest take its first steps amid predator concentrations β and clients who consider the Mara River crossings the highlight of their African lives. Both are correct. Both are extraordinary. Neither is objectively better.
What we can tell you is this: every month in Tanzania offers exceptional wildlife encounters, extraordinary landscapes, and an experience that will remain with you for the rest of your life. The question is not whether Tanzania will deliver β it always does. The question is which month delivers the version of Tanzania that speaks to you.
