When planning your dream Tanzania safari, one of the most important decisions you’ll make is when to visit. The right timing can make all the difference in your experience — whether it's the thrilling wildlife migrations, ideal weather, or the opportunity to witness the wonders of Mount Kilimanjaro.
In this guide, Incredible Africa Adventures shares everything you need to know about the best time to visit Tanzania, including the top safari seasons, weather patterns, and unique travel experiences to help you plan the perfect safari adventure.
January - March
These early months of the year are typically the hottest time of year in Tanzania (peaking in February). This season is generally dry, and is one of the most popular times for safaris. Parks may feel a bit crowded, especially around the New Year.
March - May
Mid-March through May is the “long rainy season”, marked by nights and mornings of rain. Typically, the sun makes an appearance in the afternoon and evenings are serene and peaceful.
The rains make everything lush, green and the animals are lively and active in the parks, with adequate sources of water everywhere.
However, some rough roads in the parks may be impassible, due to flooding or deep mud. Main roads in the parks are typically fine, and several parks, and Ngorongoro Conservation Area, have many sections of road which are paved and will not have any issues with driving.
This season sees significantly fewer tourists, and nearly all of the accommodations offer discounts for the low season. Guests who don’t mind rainy mornings have shared that their safari during the rainy season felt like an intimate, secluded adventure because they felt like they had the whole park to themselves to watch the incredibly active animals in the damp, green forests.
June - September
This period is considered the “cold” season in Tanzania. While for locals, the weather is cold (and you will see people wearing winter coats and hats), those visiting from other climates find the weather pleasant and fresh. Bring a jacket for chilly mornings, but afternoons are nice and generally sunny, and the weather is dry during this time.
This is another popular travel season in Tanzania, with many visitors in the national parks. If you’re not a fan of hot weather, this is the ideal time to visit during Tanzania’s dry season. This is also a common time for viewing the Great Migration in Serengeti National Park.
October - December
The short rains generally fall sometime between October and December, and the weather gets warmer as the end of the year approaches.
October is also the time when the jacaranda trees across East Africa bloom - a truly beautiful spectacle of trees crowned with purple flowers. In December the Flame Trees blossom, turning a vibrant red just before Christmas.
Christmas is a popular time for tourists to visit Tanzania and often the short rains have stopped by mid-December as well. Many visitors plan something special to mark the holiday season, such as summiting Mount Kilimanjaro to commemorate the day. Hotels and lodges may serve a special holiday meal for guests. The weather in December is usually considered ideal, however, parks and accommodations may feel more congested than other times of the year.
Tanzania offers unique experiences year-round, but the best time to visit largely depends on the wildlife you want to see, your weather preferences, and the type of safari you’re looking for.
Dry Season (June to October) – Ideal for Safari Viewing
The dry season, from June to October, is the best time to visit Tanzania for a safari. During this period, the Great Migration takes center stage in the Serengeti and Ngorongoro Crater, as wildebeest and zebras travel in massive herds, crossing rivers and grazing in the plains.

Green Season (November to May) – For a More Intimate Experience
The green season spans November to May and is less crowded than the dry season, offering a more intimate and tranquil safari experience. Though the rains come and go, the lush landscapes and baby animals are a sight to behold, especially in December to March when many species give birth.

To further enhance your Tanzania safari experience, certain events can make your trip even more memorable.
The Great Migration (June to October)
The Great Migration in the Serengeti is one of the most spectacular wildlife events on earth. Over 1.5 million wildebeest, zebras, and gazelles move across the plains in search of fresh grazing areas. During this time, you’ll witness thrilling predator-prey interactions, including crocodiles hunting wildebeest during river crossings.
Calving Season (January to March)
The calving season is when thousands of wildebeest, gazelles, and zebras give birth on the Serengeti plains. This period is a prime time for seeing baby animals, as predators also follow the herds, creating exciting game-viewing opportunities.
Birdwatching (November to April)
For bird enthusiasts, Tanzania is a paradise. From November to April, the country’s wetlands are filled with migratory birds, including flamingos at Lake Natron and Lake Manyara. This is the best time for avid birdwatchers to spot a variety of species, including rare ones.
Tanzania’s climate varies depending on the region, but overall, the country enjoys warm temperatures year-round. However, the weather does play a significant role in planning your safari.
Dry Season (June to October): Generally warm during the day, cooler at night. The best time for outdoor activities and safaris.
Green Season (November to May): Mild temperatures, but expect some rain. The wettest months are March and April.
If you’re planning to climb Mount Kilimanjaro during your visit, the best time to summit is during the dry season, from June to October. These months offer clearer skies and the most favorable weather for a successful trek.
Avoid the rainy season (March, April, May) when the mountain trails can be slippery and unpredictable.
Tanzania’s long dry season (July–September) is widely regarded as the best time to visit for an unforgettable mix of wildlife safaris, the spectacular Great Migration, mountain trekking, and idyllic beach holidays in Zanzibar. With clear skies and optimal wildlife-viewing conditions, national parks and game reserves are at their prime—but do note that this peak travel period often brings higher rates and fuller lodges.
For travelers seeking serenity and lower prices, the short rainy season (late October–December) offers lush landscapes, fewer crowds, and excellent opportunities for birdwatching and cultural encounters. While you may experience brief afternoon showers, most game drives and beach excursions proceed as planned, and you’ll enjoy off-peak rates at lodges and Zanzibar resorts.
We generally recommend avoiding the long rains (March–May), when heavy downpours can make roads impassable and force last-minute itinerary changes. Instead, choose one of the drier windows to ensure smooth logistics, maximum wildlife sightings, and the best possible experience on your Tanzania safari or mountain trek.
Whether you want to witness the awe-inspiring Great Migration, experience the peaceful green season with fewer crowds, or enjoy a Mount Kilimanjaro climb, Incredible Africa Adventures will help you plan the ideal safari package based on your preferences.
