I didn’t do an extensive study on climate since this was an organized tour. However, my perceptions were that the following were important in our trip: (a) it gets very hot in desert of Sudan. We came through at end of January and it was already getting warmer – so coming through earlier (end of December or start of January) might have been better (b) rainy season in Tanzania came not long after we were through in mid-March (c) winters in South Africa can get cold.

So if I were leaving South Africa, I’d probably shoot for spring/fall – then avoid being too hot in Namibia – and avoid rainiest times in Tanzania/Kenya and hottest times in Sudan – but not quite sure how that adds up. We did get mostly tailwinds heading south from Egypt but not sure how common that is.
