The best time to visit Uganda depends on personal preferences and interests. Uganda has a tropical climate with two rainy seasons and two dry seasons.
The dry seasons are from December to February and from June to August. These are considered the best months for gorilla trekking and other wildlife activities since the roads are passable and the weather is favorable.
However, Uganda's wildlife and landscapes are beautiful year-round, and each season offers unique experiences. During the rainy seasons from March to May and September to November, the country is lush and green, and bird watching is especially rewarding.
It's worth noting that peak tourist season corresponds with the dry seasons, so if you prefer to avoid crowds, the rainy season may be a good option for you.
Overall, the best time to visit Uganda depends on your interests, budget, and schedule. It's recommended to do some research and plan ahead to make the most of your trip.
