The Iquitos area is located a few degrees south of the equator and is characterized by strong tropical sun and rain forest. Rainfall and daily temperature fluctuation are about the same throughout the year. When rain occurs it is usually for short periods during the afternoon or night.
Humidity is quite high due to evaporation from dense jungle foliage.
