I've been in August and it should be about the same as July. The nights will be cold, but most camps provide nice, warm blankets on their game drive vehicles for the night drives or for the early mornings. The days are usually warm, so bring layers and add or subtract as needed. There are plenty of blankets on the beds, as well. I get cold easily, but didn't find it to be too cold for me.

At Hwange, the game viewing may depend on whether it's windy, or not. If it is, that can cut down on the game you see. Because it will be the dry season, the game should be heading for the waterholes. Where are you staying? I was at Somalisa in September 2010... great place!

I can't speak to the differences between Big Cave and Amalinda but I stayed at the latter in 2010. Amalinda is a beautiful and unique camp. I even had some rock art in my room. We hiked to a fabulous cave with dozens of rock art paintings one morning. In Matabo Hills NP, we saw a couple of rhinos, black and white.

1. "I get cold easily, but didn't find it to be too cold for me." Ditto for me and I bet I get even colder than ShayTay.
Layers always work. It is not true that it is warm only a few hours a day. You'll be very hot midday in July.

2. At the pans at sunset you might see a couple of vehicles gathering, but I cannot imagine a crowd anywhere. July is good time with abundant game, that is correct.

Ditto for me. I spent 4 nights and did black and white rhino extensive tracking on foot and found them. Very exciting and rewarding.

You've got yourself a nice trip! If there is any more time, include Mana Pool.

Thank you both! You've put my mind at east. We are staying at Somalisa - would love to hear more about your stay there.
