It can rain at any time of the year in the Tambopata area, in Peru, or anywhere in the Amazon rainforest but it is driest from May until October. The rainy season is from November until April and the rainiest months are from December to February. The drier season is the more popular time of the year for visitors but both seasons can be considered for your trip to the rainforest.
Advantages to coming in the dry season are that rainforest trails can be much less muddy and the likelihood of any planned activities getting cancelled will be lower. In addition, since water levels are lower, fishing can be much easier. However, it is hotter and travel times can be longer.
Upsides to coming in the rainy season are that it is cooler, there are fewer tourists and transport times are quicker. However, there are more mosquitos and hiking trails and areas where passengers embark and disembark boats will be muddier. Also, if you are coming to Puerto Maldonado by bus, the trip can take more time.
If you are very interested in seeing parrots at clay licks, bear in mind that activity fluctuates according to the time of the year and the weather.
According to research conducted by the Tambopata Research Center, the best time to see macaws at claylicks is between September and January, which coincides with their breeding season and changes in their diet. Their least active months are from April to June.
Amazon parrots, on the other hand, are active all year round and especially during the dry season.
The climate in the Tambopata area is generally warm and humid. Average maximum daytime temperatures are between 30 and 33 ºC (85 – 91 ºF). At night-time, average minimums are between 18 and 23 ºC (64 – 73 ºF).
However, there are also cold fronts (known locally as “friajes”), usually between May and September, which can bring temperatures down to 10 ºC (50 ºF) during the day and 5 ºC (41 ºF) at night. These fronts can last several days. Bring some warm clothes just in case if you are travelling during those months.
