We will be spending ten days on safari (Tarangire, Ngorongoro and Serengeti) and then three days on the beach by Pangani. (We'll be at Emayani Lodge - anyone know it?) I think I understand that it's likely to be hot with some rain during the day, and that we can probably wear light pants or shorts and short-sleeve shirts and then go to long sleeve and long pants dusk to dawn. Is this correct? Then my real question is how cool is it likely to get at night or early morning - do we need a fleece jacket or just a light sweater?
