Wildlife viewing is, in part, predicated on the amount of surface water available. During the rains (November through April) wildlife is scattered as there is abundant surface water (puddles, perennial rivers) to drink. Once the rains end (mid April) wildlife congregates around remaining surface water supplies (pools, lakes, and large rivers).
Kenya is a year round destination with excellent game viewing. One of Kenya’s greatest attractions is the annual wildebeest migration between Serengeti National Park in Tanzania and Masai Mara National Reserve in Kenya. This takes place between June and September. Traditional peak season is January to March as this is when the weather is hot and dry and most comfortable for travelling. This is a good time for bird viewing on the Rift Valley lakes. Game viewing at perennial water holes is also good at this time. April – June and October – December are the rainy seasons and flooding sometimes occurs. However, it is usually possible to get around easily during these times and the rains do not hinder visibility.
In East Africa safaris are best enjoyed during the periods mid December through the beginning of March and during the period June through mid October each year.
