June is both the coldest and driest month in the Kruger. Daytime temperatures are mild, and humidity is low, but evenings and early mornings can get quite cold.
The southern and central regions of the Kruger are best for game drives during winter since there are more rivers and other water sources, meaning these regions carry a higher population density of animals.
There are also more accommodation options here (besides camping), and you might be interested in staying indoors in the cold evening weather.
From June onwards, the Kruger’s animals, specifically the elusive big cats, become easier to spot in the sparse vegetation and tend to move around a bit more in the cooler temperatures.
Evenings and early morning game drives are quite cold, and the bushveld is not as pretty as in the summer months.
