Bit of a random question. I'm going on a camping safari in January 2017. O need to bring my own bedding. From my research I've found out that it is the raining season. I have a sleeping bag that is more suited to winter which is prefer not to bring. My question is - how cold does it get at night in the parks like Kruger and in places like Maun, Palapye and the Okavango Delta at night. Would I be fine in January with a light covering? I'm assuming it will be humid, but better to ask than just assume and be very wrong.
