The honest month-by-month guide to visiting Tanzania - what's good, what's not, and how to pick the right time for what you want to see. Updated for 2026.
Tanzania is a year-round destination, but the timing changes what you see, what you pay, and how busy it is. Most travel guides dodge the question with “it depends” - we’ll be more specific. Here’s the honest month-by-month breakdown.
The short answer
If you can pick any time, June to October is the dry season and the best time for most travellers. The wildlife is concentrated around water, the rains have cleared the air, and the Great Migration is on the move. June to August is peak season, with the highest prices and the most visitors - book 6 to 12 months in advance for the best lodges.
January and February are the runners-up. The southern Serengeti hosts the wildebeest calving - half a million calves in a few weeks, and the predators are intensely active. The weather is warm and mostly dry, and the parks are less busy than in peak season.
November and March, April, May are the shoulder and wet seasons. November is the “short rains” - usually just a few passing storms, with most days still fine. March to May is the “long rains” - afternoon showers, lush landscapes, fewer visitors, and the lowest prices of the year. Some lodges close in April.
Month by month
January - excellent
Dry, warm (25–30°C), and the start of the calving season in the southern Serengeti. Birding is at its best. The beaches on Zanzibar are warm. A strong month for almost any trip.
February - excellent
Peak calving. The southern Ndutu area is the place to be - predator action is constant. The Ngorongoro Crater is green and lush. Zanzibar is at its driest. Still excellent for Kilimanjaro climbs (less crowded than mid-year).
March - variable
The long rains are starting. Mornings can be clear, but afternoon showers are common. Many lodges are still open. Prices drop. The southern parks are at their most lush. We don’t recommend the safari in March for first-timers, but it’s a wonderful time for return visitors who don’t mind the rain.
April - challenging
The wettest month. Some lodges and camps close. Roads in the southern Serengeti can be tough. Zanzibar is humid. Not recommended for first safari trips, but the cheapest time of year.
May - variable
Like April, but the rains start to ease at the end of the month. The southern parks are spectacularly green. Very few visitors. We don’t usually recommend it, but it has its moments.
June - excellent
The start of the dry season. Game viewing improves rapidly as the grass dies back. The Great Migration is in the central and western Serengeti. Temperatures are pleasant (22–28°C). Book early for peak lodges.
July - excellent
Dry, cool, and busy. The Great Migration is moving north. Predator action is good across the parks. Kilimanjaro climbs are at their busiest - book routes well in advance. Zanzibar is dry and cool.
August - excellent
Peak of the peak season. The Great Migration is reaching the northern Serengeti and the Mara River crossings begin. The northern Serengeti is the place to be (book 12 months ahead for mobile camps). High prices, lots of visitors, but the wildlife is exceptional.
September - excellent
The Mara River crossings continue. The herds are spread between the northern Serengeti and the Masai Mara. Wildlife viewing in the central Serengeti is excellent. The Ngorongoro Crater is at its best. Slightly less busy than August.
October - excellent
The end of the dry season. Animals are concentrated around water. The herds start moving south. The southern Serengeti is the place to be at the end of the month. The Ngorongoro Crater is excellent. Still warm, still dry.
November - variable
The short rains. Usually just a few passing storms, with most days clear. The southern Serengeti is starting to come alive again. Zanzibar has some rain but is still warm. Prices drop. A great time for a quiet trip.
December - excellent
The rains are easing. The calving season is starting in the south. Wildlife is on the move again. Zanzibar is warm and dry. Christmas and New Year are busy - book well in advance for the popular lodges.
Picking the right time for what you want
Great Migration
The crossings happen July to October in the northern Serengeti and Masai Mara. The calving is January to February in the southern Serengeti. Both are spectacular; the timing depends on what you want to see.
Big Five and predator action
Year-round in the northern circuit, but the dry season (June to October) makes viewing easier. The southern Serengeti is exceptional in January and February (calving brings the predators).
Kilimanjaro
The two best windows are January to mid-March and June to October. The dry season is the busiest; the shoulder months (December, March) are quieter. Avoid the long rains (mid-March to May) for first-time climbers.
Zanzibar
Year-round. The dry seasons (June to October and December to February) are the most popular; the long rains (March to May) are humid but cheap. The ocean stays warm (26–32°C) year-round.
Birding
November to April is best for Palaearctic migrants and resident species. Over 1,100 species have been recorded in Tanzania; a 12-day trip in this window can yield 400–500 species.
Photography
The dry season (June to October) has the best light, the most predictable weather, and the easiest game viewing. January and February are excellent for the calving.
The bottom line
If you have flexibility, June to October is the safe choice. If you can be more specific, think about what you want to see - the calving (Jan–Feb), the crossings (Jul–Oct), the cheapest prices (Mar–May), or the warmest beach weather (Dec–Mar). The rest of the year is still excellent, just with a few tradeoffs.
