The best time to visit Pantanal is from April to October, when there is less rain and the water levels come down. The best months for wildlife spotting are between July and October, when the lakes and rivers have started to dry out and shrink, so most of the wildlife moves towards the edge of the remaining water. At night during these months, temperatures can drop as far down as 10°C / 50 °F, so come equipped! The rainy season from November to May is the best time to see the flora in full bloom and to travel into the more inaccessible parts of the marshes by boat.
