What this means for the 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 attractions is shown in Will it be full? and the live bridge queue in Bridge queue.
