Same here, heat and humidity is the last thing I'm looking for.

Nevertheless, my favorite SA month by far is November, even though I usually visit the hottest corner of the country. It is springtime; unless there is a drought on everything is lush and green; flowers everywhere; birds singing in breeding plumage; impala drop their lambs; and so forth. Hot as hell unless the rain is pouring down, but I don't find the game viewing that much worse than in winter. You just need to put in a bit more effort at times.

I've also visited in January more times than I can remember. It is perfectly fine. Hot, humid and at times very wet, but I figure that easily beats the dry, dreary and drab winter.
