I'll be hunting with Vaughan in May of 2005. I would suggest any time from May through August. The hunting in May-June has the advantage that the animals really haven't been hunted prior to this time, so are a little less skittish. The advantage to July-August is the grasses and brush have dried out so visibility is a bit better. You really can't go wrong with either period. Temperatures should range from 30's or 40's in the morning up to 70's and 80's by afternoon. Humidity is very low-10 to 20 percent, and virtually no chance of any rain. Insects are also at a minimum that time of year. In May the Kudu are still in rut too. I guess what I'm trying to say is to pick a time May thru August, and have a ball.
