May continues to be a good time for the Indian Ocean beaches, especially Mauritius, the Seychelles and Mozambique.
Namibia is dry and not too hot and ideal for a camping safaris or a self-drive tour.
In Zambia it’s the beginning of the new season, especially in the Lower Zambezi, but Kafue is still very wet.
The season is beginning again in Madagascar.
Avoid most East African destinations, as this is the season of the long rains, and many safari lodges close. In Zanzibar, virtually all lodges close as the rainy season arrives.
Rwanda and Uganda are also experiencing rain which can make gorilla trekking difficult.
The rains have well and truly arrived in Sierra Leone and travel becomes much more difficult.
Although Ecuador and the Galapagos Islands can be visited all year round May is as good a month as any to experience the islands that shaped our understanding of evolution, and a cheaper time as its not high season.
