Best Time for the Iguazú & the Pantanal
Sweet spot: June, July, August — computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
The dry season stacks the Pantanal's wildlife along shrinking rivers and keeps Bonito's water gin-clear.
The falls run biggest after summer rains — thunderous, misty, and hot as the jungle it sits in.
