Rainfall in the Amazon increases in November to about 166mm average for the month, adding about 40mm to the rainfall in October. So the dense Amazonian jungle is getting wetter as the summer draws in, but you can still embark on the same activities as in October, as the water levels won’t have risen. This means you can try piranha fishing, swim near pink river dolphins, enjoy night time walks in the jungle and much more. Wildlife sightings in the Amazon can be good, but the jungle is very dense, making most mammal species hard to find. Watch out for lots of colourful birds.
Summer is drawing in on the Pantanal Wetlands too, with an increased rainfall and quite warm temperatures. Wildlife can still be seen on the river banks at this time, but with the additional water around, sightings can be a little rarer than say June to October. The first two weeks can of November are still pretty good for jaguar spotting if that is the focus of your trip and horse-riding through the Pantanal can be stunning in November.
Rio is seeing heightened temperatures and rainfall too, making it more humid. If you don’t mind the humidity, you can still explore all of Rio’s cultural and city sights, as well as the beaches.
