Best time to visit Tanzania

Tanzania attracts visitors year-round with its vast savannahs, majestic mountains and, of course, stellar safaris. But when is the best time to visit Tanzania? While the dry season – stretching from June to October – is ideal for wildlife spotting, don’t discount the wet season. The short rains of November and December lend themselves to lower rates and fewer crowds. Visitors can catch the herds as they travel south from Kenya and arrive in the north of the Serengeti National Park in November and early December. Despite the showers, Tanzania’s ‘green season,’ from November to March, also promises plenty of migratory bird sightings. Read on for our month-by-month rundown of Tanzania’s weather so you can plan the perfect getaway...

Tanzania month by month

January in Tanzania

Visit Tanzania in January for sightings of newborn wildlife. The temperature remains high throughout the month, with a chance of rain, as wildebeest calving season commences in the southern Serengeti and the Ngorongoro Crater (a UNESCO World Heritage site). As January falls within the shoulder season, expect fewer crowds across Tanzania’s national parks and enjoy lush green landscapes brought to life by December’s short rains.

The Ngorongoro Crater

Located in the heart of the Ngorongoro Highlands in northern Tanzania, the Ngorongoro Crater, is in a tropical climate zone. There are two rainy seasons, as in most other parts of Tanzania, with the short rainy season from November to December and the long rainy season from April to May. During the latter, the monsoon from the Indian Ocean brings high rainfall. The southern and eastern slopes of the Ngorongoro Crater receive the most rainfall during this period. During the southern winter (our own summer), it is cold on the crater, especially at night.

Lake Eyasi

Lake Eyasi is located in the Great Rift Valley in eastern Tanzania, close to an area of plateaus and volcanic peaks. Lake Eyasi is at the southernmost limit of the Ngorongoro range. Lake Eyasi almost dries up during the dry season between June and September. The rainy season runs from January to May, with most of the rain falling in April to feed the lake.

Lake Natron

Lake Natron, not far from Mount Gelai, has very different weather from Tanzania's capital. While temperature variations in Tanzania are small, and fairly mild, near Lake Natron, temperatures frequently exceed 40°C. The Lake Natron area is very dry with little rainfall. This 'lake of fire' and its surroundings thus experience a very harsh climate all year round.

Mount Kilimanjaro

Kilimanjaro has a tropical savannah climate. It is hard to define a type of climate for Kilimanjaro, as climatic conditions vary according to where you are on its slopes. Temperatures are mildest at the foot of Kilimanjaro, with an average annual temperature close to 24°C. With altitude, this temperature decreases, reaching an average of 5°C at 13,100ft, and finally -7 °C at the top. It is at the top, and in the 13,100 to 16,400ft altitude zone, that very large temperature changes can occur within a day, with differences of 40°C (change between day and night). In general, Kilimanjaro has a dry season, particularly from mid-June to mid-October, and another hot and dry period from early December to the end of February. At this time, temperatures are mild. The long rainy season runs from late March to mid-May.

Serengeti National Park

Serengeti National Park has a tropical climate. Like the rest of Tanzania, there is a dry season from June to October, and two distinct rainy seasons. The first, with 'long rains', runs from March to the end of May, while the short rains occur from November to December.

Selous Game Reserve

Selous Game Reserve, covering 19,300 square miles, is a protected area of Africa in south-eastern Tanzania. From June to September, the days are warm and the nights are cool but pleasant. Then, from October to November, the hot, dry season arrives, with a climate that changes dramatically, becoming humid. Rain is much more frequent, culminating, between April and May, in the main rainy season (when the Selous Reserve is not accessible).

Zanzibar

Zanzibar has an equatorial climate, with strong Indian Ocean winds at certain times of year. The hottest month of the year in Zanzibar is undoubtedly February, while the coolest month is August. Heavy rainfall in Zanzibar is concentrated in April and May (and light rainfall from late October to late November). The driest period in Zanzibar is June to October.

A word from our specialists

If you’re a keen climber or a wildlife enthusiast, the best time to visit Tanzania is between June and September, when the dry season extends across the country, and the Great Migration is in full swing. If avoiding crowds is a priority for you, we recommend timing your visit to coincide with the wildebeest calving season in January and February. During these months, high temperatures and rainfall keep the crowds to a minimum.

What our clients say about their Tanzania trip

4.8 / 5
"The trip was very well thought out. We were all first-time travelers to Tanzania and new to safaris, and the way the trip was organized meant that we were eased into the safari experience in a very comfortable way. We dipped our toes in at our first location, and the trip ended with a bang in a beautiful rustic camp. Issaya, our first guide, really made the trip amazing - he was so knowledgeable and we had total trust in him. "

"All of the camps were clean, the food was incredible all week, and we always felt very safe. The safari providers were so knowledgeable: both guides were excellent in their knowledge of the animals, birds, plants, landscapes and local culture. Their ability to find animals in the bush was almost unbelievable. This was our first safari, and the trip exceeded all of our expectations - there was at least one memorable moment every single day."
