Rain in Iquitos

Iquitos weather is one of those things you either love or you hate for an extended period of time. As with other tropical areas, there are no seasons in Iquitos usual to temperate areas. This means there is no autumn, spring, summer, or winter. I still don’t really know which month is meant to be what as I lived in the northern hemisphere for half my life and the southern hemisphere for the rest. I went from seeing Christmas cards with snowmen wearing scarfs to Christmas cards of snowmen wearing sunglasses and swimming trunks.

I find Iquitos simply having a wet season and drier season much easier to understand. When it’s wet, it’s probably the wet season. This is a bit of an oversimplification as you really need to know what ‘wet’ means in the rainforest, which sets its norm as a wet climate. Officially, there is not even a dry season in Iquitos as rainfall doesn’t really change much between months, but it does get heavier around October/November. This then lasts about half the year until May/June. April brings the most rain and is the height of the wet season. To get technical, the wet season receives around 300 mm each month and the drier season receives 100 mm less. This is not considered enough to deem the name “dry season.” September is the driest month.

Temperature in Iquitos

Temperature in Iquitos doesn’t really change between months and of a daytime reaches about 30 – 32°C (86 – 90°F) and then has cooler nights of 20 – 22°C (68 – 72°F). The wetter season October/November – May/June is a little hotter by one or two degrees. I have been in Iquitos for over a month both in the wetter and drier seasons and found the temperature pleasant.

Humidity in Iquitos

Following from the tropical heat and rainfall, Iquitos has a high humidity compared to temperate areas. The daily high humidity doesn’t change much from around 98 to 100% but the daily low humidity of 60 to 70% is at its height in the wetter season (October/November – May/June).

Wind in Iquitos

Wind doesn’t really change at all from a gentle breeze but there is a gentle increase in wind speed over the wetter season (October/November – May/June).

Best Time to Visit Iquitos

Despite many recommendation that the drier season is the best time to visit Iquitos, the wetter season is when waters rise giving deeper access to the forest with canoe. This is the time when the forest blooms with flower and when trees drop their fruit, which draws birds and primates in particular places for abundant food. The drier season is also good as hiking is better and pools of terrestrial water shrink concentrating Amazon Rainforest animals.
