You will love it. I know Marco and the area quite well, it is very beautiful and situated up against the northern edge of the Waterberg. Mornings will be chill, you get frost in the lowlaying valleys in winter but by late august the days will warm up, if there is no wind it will get hot. August September is before the rainy season so it will not be humid unless there are early rains. Our annual Traditional shoot is held on a neighboring farm, the area is vrot with bushpig, warthogs etc. Magical huge Kudu!
Enjoy!
