The temperatures are particularly high when gorilla tracking in July. This is also increased by the exertion of trekking and the recommendation of wearing longer (but lightweight) trousers and sleeves when in the forest. In the rest of the country, temperatures will be slightly cooler particularly around Lake Victoria due to the location being at altitude. Mornings and late evenings may still be cool so it is always good to have extra layers on hand.
Although children under the age of 15 cannot participate in gorilla tracking, thanks to the plethora of other safari options July can still be a good time to take a family holiday to Uganda.
