What this means for the tour
On rainy days, the Falls remain impressive (bring a light raincoat) and Itaipu is barely affected — most tours are covered. A low of 10°C calls for a real coat, especially early morning and at night. The likelihood of full capacity by attraction is in Will it be full? and the live bridge queue in Bridge queue.
