How is the weather in Iquitos?

Amazon Rainforest

Unlike the Northern Hemisphere with its summer and winter, or subtropical zones with wet and dry seasons, Amazon rainforest weather has a high-water season and a low-water season.

The water can rise and fall up to 40 feet annually, primarily due to snow melt from the Andes and some from rainfall. The low-water season is from May/June to October/November and high-water season is from October/November – May/June. There is a slight difference between the wetter and drier months, but this is only by one or two degrees with the wetter season being slightly hotter. To be really accurate, there technically isn’t even a dry season because it rains about 200 days per year. That’s why it’s called the rainforest!

Iquitos City itself has microclimates—meaning, rain can be present in one area of the city, and sunshine in another. Iquitos can also experience a phenomenon called “urban heat island.” At times, the hot air does not dissipate as readily so it can be hotter in the city than the natural climate of the Amazon jungle.A good reason to escape to the jungle on a cruise or an expedition!
