Weather in the Pantanal
The Pantanals climate is related to the climatic conditions of the Upper Paraguay Basin, as well as being the result of its tropical geographic location, between 16 ° and 22 ° South latitude and 55 ° and 58 ° West, its relief and occasional entry of masses of cold air coming from the South. The Pantanal presents average temperatures around 26 ° C. The summer is the warmest and rainy period. Dry winter has its average temperature slightly lower, but strong temperature fluctuations are common in the winter and therefore temperatures can rise much above or descend much below the average with occasional extremes of well below 10 º C. Occurrences of these are due mainly due to the ease in the transfer of cold air coming from the pampas and to the absence of oceanic influences. The average annual precipitation reaches 1,200 mm. with the main rainfall occurring between November and March, months in which the Pantanal receives about 70% of its annual rainfall quota.
The drought period occurs from June to September and during these months the Pantanal receives an average of only 10% of its annual precipitation.
What is the best time to visit the Pantanal?
This is always a difficult question to answer. Both flood and drought present advantages and disadvantages for the human visitor. For the observation of the fauna in a general way, the drought can be considered the best season because it forces the majority of the animals to look near the rivers, where then we can sometimes find large concentrations of animals. In the flood, the animals spread over the entire surface of the Pantanal because they have access to water everywhere, which may make it difficult to observe them. Even when flooded however, we can see animals in abundance in the Pantanal and the landscapes are undoubtedly even more beautiful. In the dry we can have difficulties in making boat trips, while we make walks on all sides. In the flood we can surf at will, but we can be difficult to walk.
The weather cycle makes the Pantanal constantly changing, with obvious consequences for visitors. So we would say that the best time to visit the Pantanal is that of the greatest convenience for every visitor.
