Uganda's raised topography means a cooler climate than its equatorial setting suggests but if you're planning a gorilla trek, it's important to know when to go to Uganda for the easiest trekking conditions. Although it's regarded as a year-round activity, the best time to visit Uganda for gorilla trekking is during the country's two dry seasons: January and February and from June to September.
Game viewing in Uganda's savannah parks is best at the end of the dry seasons - February and March and September/early October - when wildlife is concentrated around water sources. Bird watching is fantastic all year round but is at its peak between November and April when migrant species are present. We'd recommend avoiding a Uganda safari entirely during the heavy rains of April and May.
