What this means for your visit
On rainy days, the Falls remain impressive (bring a light raincoat) and Itaipu is hardly affected, as most tours are covered. A low of 11°C calls for a real jacket, especially early morning and at night. The likelihood of full capacity for each attraction is shown in Will it be full? and the bridge queue, live, in Bridge queue.
