Tanzania Weather: Climate,
Seasons & What to Expect
Tanzania’s weather is shaped by altitude, coastline and proximity to the equator — and it varies more than most travellers expect. Understanding how Tanzania’s climate works across regions and seasons will help you pack the right clothes, choose the right month, and get the most out of your safari and beach experience.
Tanzania’s Climate at a Glance
Tanzania sits just south of the equator on Africa’s east coast, but the word “tropical” only tells half the story. The country’s climate is driven by three main factors: altitude, distance from the Indian Ocean, and seasonal wind patterns.
Much of the interior sits on a high plateau between 1,000 and 1,500 metres above sea level, which keeps temperatures mild and comfortable for most of the year. The northern safari parks — Serengeti, Ngorongoro, Tarangire and Lake Manyara — sit at elevations between 900 and 2,300 metres, meaning daytime warmth gives way to surprisingly chilly mornings and evenings, particularly between June and September.
The coastal strip, including Dar es Salaam and the Zanzibar Archipelago, is hot and humid year-round, with temperatures rarely dipping below 25°C. Inland areas in the south and west, including the parks around Selous/Nyerere and Ruaha, are also warm but with lower humidity than the coast.
At the extreme end of the scale, the summit of Mount Kilimanjaro is permanently below freezing — a reminder that Tanzania’s weather can change dramatically within just a few hours of driving.

Understanding Tanzania’s Seasons
Dry Season (Jun–Oct)
The most popular time for safari. Rare rainfall, clear skies, and thinning vegetation makes wildlife easier to spot. Pleasant days of 25–30°C in lowlands; mornings as cold as 5–10°C at Ngorongoro.
Short Rains (Nov–Dec)
Lighter, shorter showers — often in the late afternoon. Mornings are typically sunny. The landscape turns green, skies are dramatic, parks are quieter, and prices drop.
Short Dry Season (Jan–Feb)
Among the hottest months. Coast temperatures reach 32–34°C. In the northern parks, conditions are warm and largely dry. This is calving season in the southern Serengeti.
Long Rains (Mar–May)
The heaviest rainfall of the year. Rain typically comes in intense afternoon bursts. Northern parks stay open year-round; some southern lodges close in April–May. Lush landscapes and the lowest prices.

What to Pack for Tanzania’s Weather
Tanzania’s varied climate means layering is key. What you need depends on where you’re going and when, but a few essentials apply across the board.
For safari (northern parks, dry season): Lightweight, neutral-coloured clothing for warm days, but bring a fleece or warm jacket for early morning and evening game drives — especially at Ngorongoro. Avoid dark blue and black, which attract tsetse flies.
For Zanzibar and the coast: Light, breathable fabrics. A sunhat and high-SPF sunscreen are essential. If you’re visiting towns or villages outside the resort areas, modest clothing is respectful — cover shoulders and knees.
For the rainy season: A lightweight, packable rain jacket is more useful than an umbrella. Quick-dry fabrics are your friend. Roads can be muddy, so closed-toe shoes or boots are better than sandals on safari.
For Kilimanjaro: You’ll need full cold-weather gear for the summit, including thermal base layers, a down jacket, gloves, and a warm hat. Most trekking operators provide detailed packing lists.
Year-round essentials: Insect repellent (DEET-based), sunglasses, a reusable water bottle, and a light scarf or buff that doubles as sun protection and dust cover on game drives.
What is the weather like in Tanzania year-round?
Tanzania is warm to hot throughout the year, with temperatures moderated by altitude in the interior. The coast and Zanzibar are hot and humid year-round (28–34°C), while the northern safari parks are milder (20–28°C daytime, 8–15°C at night). There is a dry season from June to October and a rainy season from November to May, with the heaviest rain falling in March to May.
When is the rainy season in Tanzania?
The rainy season in Tanzania runs from November to May, but it’s split into two phases. The short rains (vuli) fall from November to December and are lighter and less disruptive. The long rains (masika) last from March to May and bring heavier, more sustained downpours, particularly in the south and on the coast.
Does it rain every day during the rainy season?
No. Even during the long rains, mornings are usually dry and warm. Rain tends to arrive in the afternoon or evening as intense but relatively brief thunderstorms. It’s rare for rain to persist all day, and safari game drives typically continue without issue.
Is Tanzania too hot to visit in January and February?
January and February are the hottest months, especially at the coast where temperatures can reach 34°C with high humidity. However, the northern safari parks at higher altitude remain comfortable, and this is prime time for witnessing the wildebeest calving in the Serengeti. If heat isn’t your thing, the dry season months of June to September are cooler and more comfortable.
What’s the best time to visit Tanzania for good weather?
June to October offers the driest, mildest conditions across the country — ideal for both safari and beach. January and February are also dry and warm but hotter. For a balance of good weather, fewer crowds, and lower prices, consider June or late October.
