Tanzania is a land of extraordinary contrasts where vast savannahs meet tropical coastlines, and snow-capped peaks rise above lush forests. From the sweeping plains of the Serengeti to the spice-scented shores of Zanzibar, and the majestic slopes of Mount Kilimanjaro, Tanzania’s climate varies greatly by region and altitude. Understanding the country’s weather patterns is key to planning your ideal safari, mountain trek, or beach retreat. At Mountains 2 Marshes Expeditions, based in Arusha, we help travelers choose the perfect time to experience Tanzania’s magnificent diversity in comfort and style.

General Climate Overview

Tanzania enjoys a tropical climate with warm temperatures year-round, influenced by elevation and proximity to the Indian Ocean.

• Coastal regions such as Dar es Salaam and Zanzibar are typically hot and humid.
• The northern highlands around Arusha and Kilimanjaro are cooler, thanks to higher altitude.
• Average daytime temperatures range from 25°C to 32°C (77°F to 89°F), though nights can be significantly cooler in the highlands and national parks.
• The country experiences two primary seasons: the dry season and the wet (rainy) season, each offering unique travel opportunities.

The Dry Season (June to October)

The dry season is the most popular time for safaris and outdoor adventures across Tanzania. Days are sunny, clear, and comfortable, with low humidity perfect for wildlife viewing and mountain climbing. Vegetation thins out, making animals easier to spot as they gather near rivers and waterholes. Parks such as Serengeti, Ngorongoro, Tarangire, and Lake Manyara offer exceptional game viewing during this period.

This is also the best time to climb Mount Kilimanjaro or Mount Meru, as trails remain dry and visibility is outstanding. Daytime temperatures average 20°C to 30°C (68°F to 86°F), but mornings and evenings can be cool, especially in highland regions.

The Short Rains (November to December)

The short rainy season brings brief, refreshing showers, often in the late afternoons or evenings, without significantly affecting safari plans. The rains revive the landscape, painting the plains lush green once again a delight for photographers and nature lovers.

Visitor numbers drop slightly, offering a more peaceful and intimate safari experience. This is also a fantastic time for birdwatching, as migratory species return to Tanzania’s lakes and wetlands.

The Long Rains (March to May)

From March through May, Tanzania experiences its long rainy season, characterized by heavier and more persistent rainfall, particularly in April. Some remote lodges and camps may close temporarily due to accessibility challenges. However, for those who don’t mind occasional rain, this season offers a beautifully green landscape, fewer tourists, and excellent photography conditions with dramatic skies and vibrant colors.

Accommodation rates are typically lower during this time, making it a great option for travelers seeking value and solitude. Temperatures range from 22°C to 28°C (72°F to 82°F) depending on the region.

The Warm Season (January to February)

These months are generally warm and dry, especially in northern Tanzania, making them another prime window for safaris. In the southern Serengeti, this is the wildebeest calving season, when hundreds of thousands of young are born, attracting predators and creating spectacular wildlife moments.

Along the coast and on the islands of Zanzibar, Pemba, and Mafia, travelers can expect hot, sunny days ideal for beach relaxation, diving, and snorkeling. Coastal temperatures typically range from 28°C to 34°C (82°F to 93°F), with cooler evenings inland.

Regional Weather Differences

Tanzania’s weather varies widely across its distinct regions:

• Northern Safari Circuit (Arusha, Serengeti, Ngorongoro, Tarangire): Moderate climate year-round, cooler mornings and evenings due to elevation.
• Southern Parks (Selous, Ruaha, Mikumi): Warmer climate with more intense rains between March and May.
• Coastal and Island Regions (Zanzibar, Pemba, Mafia): Hot and humid throughout the year perfect for beach holidays.
• Western Parks (Katavi, Mahale): Follow similar weather patterns but can be challenging to access during heavy rains.

Weather Tips for Travelers

• Pack light, breathable clothing for daytime and a light jacket or sweater for early mornings and evenings.
• Bring waterproof gear if visiting during the rainy months, especially in April or May.
• Stay hydrated and use sun protection, as UV levels can be strong in open savannah areas.
• Plan your trip based on both weather and experience goals. For example:
  • To witness the Great Migration, visit between June and September.
  • For beach relaxation, choose January to March or June to October.
