Take a poncho. You won't need it for warmth, but they have them that fold into a small packet and tuck in your bag. Mine was invaluable and used a lot in May when I first went to Kenya. I was on a safari, but we got in and out of the vehicle and sometimes were standing out in the rain. It was very beautiful then, but you will be better prepared in case you need to put your camera under it in a flash. Liz
