Best Time to Visit
Cruising the Amazon river and rainforest ecosystem is like seeing a giant living and breathing creature. The significant ebbing and flooding of the Amazon River and its tributaries between seasons replenish the waters with vital nutrient. The cycle also dictates the rhythm of life for so many species including plants, fish, amphibians, reptiles, mammals and the local people — the ribereños. As for the ‘best time to visit’ the Amazon, here’s two facts explorers need to know:
- As the name suggests, the Amazon rainforest sees rainfall throughout the year regardless of month or season. (Read our ‘Weather’ section on this page.)
- The Amazon experiences microclimates. This means that rain can occur in a particular localised area while other areas remain sunny.
- You will see spectacular Amazon wildlife, birds and plant life at any time of year. For instance, you can definitely see the Amazon’s rare pink river dolphins.
High vs. Low Water Seasons
There are two key seasons in the Peruvian Amazon: a low water season that lasts from June to November and a high water season from December through to May. Cruising in either season presents explorers with a unique experience of the Amazon as water levels differ as much as 23 feet (7 meters)!
Weather and Rainfall
A perfectly balanced rainforest ecosystem has both sunshine and rainfall, and the Amazon is no exception. The Peruvian Amazon receives a healthy 12 feet (3.6 meters) a year on average and experiences 250 rainy days.
The good news: It rarely rains for more than an hour or two. Rain most often falls in passing cloudbursts, in line with the microclimate weather behavior of the Amazon ecosystem.
Aqua Expeditions taps on the collective experience of our crew and guides in the Amazon to create an itinerary that ‘works with the weather’, for instance conducting excursions at times when rain is less probable.
Our local naturalist guides are also adept at sensing the weather before it changes. Guests receive sturdy ponchos in the event of inclement weather, so they can stay extremely comfortable and focus on the astonishing Amazon jungle scenery and wildlife.
The Low Water Season (June to November)
This is the warmer of the two seasons, with temperature averaging about 98 degrees Fahrenheit (36-37 degrees Celsius). The low water season receives 20-25% less rainfall than the high water season.
The High Water Season (December through to May)
At this time the average temperature is 86 degrees Fahrenheit (30 deg Celsius), 12 deg F (6-7 deg C) cooler than in the dry season. Although the water levels swell significantly, the increase in rainfall is relatively less drastic: 20-25% higher than that of the low water season. For example, an hour’s rain may last about 15 minutes longer.
Humidity: The humidity level in the Peruvian Amazon stays constant throughout the year at around 80%.
