Rwanda in December
Highlands and medium-altitude regions, for instance Kigali, Lake Kivu and Volcanoes and Nyungwe National Parks, are warm to hot by day, and comfortably cool by night.
Low-lying Akagera National Park is hot by day, and warm by night.
December falls within the short rainy season and monthly rainfall in most parts of the country is high (100mm or higher).
December is not an optimum month for tracking gorillas and chimpanzees, since conditions tend to be quite wet underfoot and there are frequent showers, though this is less of a risk towards the end of the month. That said, plenty of people do track gorillas in December and you’ve a better chance of a last-minute permit. Climbing the volcanic peaks of the Virungas will be tough at this time of year.
For birdwatchers, resident species are boosted by a large number of Palaearctic migrants between November and April.
