Weather
Tanzania is a tropical country, and temperatures are fairly consistent year-round, at about 77°F–86°F (25°C–30°C) on the lowlands and at the coast, and around 59°F–68°F (15°C–20°C) in the highlands. The most significant variables are altitude and rainfall. The long rainy season, which starts in late March, tends to wrap up in early June. From the middle of the month, you can expect clearer skies and slightly cooler temperatures with less humidity.
Crowds & Costs
June is the start of the peak season for travel to Tanzania, as the conditions are excellent for a wide range of activities. Lodges and hotels around the national parks, the mountains, and the coast around Zanzibar will likely be fully open in June as visitors arrive for safaris, mountain climbing, and beach vacations. If you want to get a deal on accommodation and avoid most other visitors, early June may be quieter and less in-demand than later in the month, although the trade-off is more rain. Lodges in the Serengeti, especially the western part, will have peak-season prices throughout June as visitors are attracted to the wildebeest migration.
Where to Go
If you're interested in a physical challenge that doesn't require any technical expertise, why not try climbing Mount Kilimanjaro in June? A somewhat easier (and shorter) alternative is nearby Mount Meru. The highest and second-highest mountains in Tanzania, respectively, are located in the country's northeast. June is a great time to embark on these "walk-up" climbs because the weather is mainly dry and clear, meaning the paths won't be too slippery, and the views across Tanzania and as far afield as Kenya will be great. You can also go on wildlife-spotting safaris in the surrounding national parks and nature reserves before or after a climb.
For bird watching, head to the parks in the south of Tanzania, where there are many endemic species, and the parks are full of migratory species at this time. Check out the Selous Game Reserve, a UNESCO-listed site; the rainforest-covered Udzungwa Mountains National Park; the wetlands of the Ruaha National Park; and the Kilombero Floodplains, among the most extensive floodplains in Africa.
Chat with a local specialist who can help organize your trip.
What to Do
June is prime safari time in Tanzania. To see migrating wildebeest moving in herds across the plains, head to the Grumeti, in the western Serengeti, in June and July (they will have left eastern parts of the park by June). Elsewhere you're less likely to spot the animals migrating, but you will likely see them congregating around waterholes as the rains dwindle. As plants dry out and shrink in the hotter, drier weather, it's also easier to spot animals, as they're less hidden by vegetation.
On a practical level, June (and through to October) is a comfortable time to go on safari because temperatures are a bit cooler, humidity lower, and there are fewer biting mosquitoes around.
Events in June
Bulabo Dance Festival, Bujora. The Sukuma Museum in the small town of Bujora, west of the Serengeti National Park, hosts an annual dance festival, where local dancers perform with animal props.
