Best Time to Travel: The best wildlife viewing months in Kenya are during the dry season from late June to October. The wildebeest migration usually reaches the Masai Mara in July and remains until October when they move back to the Serengeti in Tanzania. Wildlife viewing is good year-round, but this can differ for some parks.
December to February sees the birth of new zebra and wildebeest so you may have the opportunity to see these young take their first few steps! Certain parks in Tanzania also have a short dry period in January and February between the short rains of November/December and the long rains of March to May.
June to October can be a busier time of year due to the Great Migration, however, this is also the best time to see much of the wildlife gathering around remaining waterholes due to the low rainfall throughout the winter.
