To prepare for the wintertime freezing temperatures, you should have warm layers of clothing and thick outdoor clothing. Footwear should have warm lining and thick soles. Warm headgear, woolly socks and good gloves are all part of winter clothing. It is important to remember to cover your face with for instance a scarf or commando mask, especially for small children and especially for harsh freezing temperatures. The wind chill always increases the strength of the freezing temperatures.
Warm safari equipment may be hired from the local safari companies.
In other times of the year, it is also worth packing something warm but you should remember that during the summer from June to August it can also be very warm.
You will not have to worry about mosquitoes during midsummer. They do not really appear in the town areas, and if you go into the forest, it is sufficient to wear long sleeves and trousers. The food shops and service stations sell very effective mosquito repellents.
