The Ultimate Guide: When is the Best Time to Visit Tanzania?

Planning a safari? Discover the best time to visit Tanzania for the Great Migration, Kilimanjaro trekking, and Zanzibar beaches. Read our seasonal guide.

Deciding when to book your Tanzanian adventure is the first step in planning the trip of a lifetime. The short answer? June to October is widely considered the peak season for game viewing.

However, Tanzania is a year-round destination. The “best” time actually depends entirely on what you want to see. Do you want to witness the dramatic river crossings of the Great Migration? Or would you prefer the lush green landscapes and baby animals of the calving season?

At Kilinyota Safaris, we customize trips based on seasonal movements to ensure you are always in the right place at the right time. Here is our expert breakdown.

The Dry Season: June to October (Peak Safari)

Best for: First-time visitors, The Great Migration (River Crossings), and big cat sightings.

This is widely considered the best time to visit. The weather is cooler and dry, meaning animals congregate around waterholes, making them easier to spot. The bush is thin, so spotting a leopard in a tree or lions stalking prey is much easier.

  • June – July: The Great Migration moves into the Western Corridor and the Grumeti area.
  • August – September: The iconic Mara River crossings occur in the Northern Serengeti. This is high-drama action.
  • Weather: Sunny days, cool mornings and evenings.

Kilinyota Tip: Because this is peak season, parks can get crowded. We recommend booking at least 6–12 months in advance to secure the best lodges.

The Green Season: November to March

Best for: Bird watching, photography, baby animals (calving), and lower rates.

Often called the “short rains” (November/December), this period transforms the dusty savannah into a vibrant green paradise. This is not just a rainy season; it is the season of life.

  • January – February (Calving Season): In the Southern Serengeti (Ndutu region), thousands of wildebeest calves are born daily. This draws in massive numbers of predators (cheetahs, lions, hyenas) looking for an easy meal.
  • Birding: Migratory birds arrive, making this the premier time for ornithologists.
  • Crowds: Far fewer tourists, meaning you can often enjoy a pride of lions all to yourself.

The Long Rains: April to May

Best for: Budget travelers and adventurous photographers.

These months see the heaviest rains. While some lodges close for maintenance, those that stay open offer significant discounts. The landscapes are dramatic and moody—perfect for professional photographers—but road conditions can be muddy.
