Being on the equator, the weather in the Amazon is relatively constant throughout the year. The climate is tropical meaning hot and humid with plenty of sunshine and rainfall. Average temperatures range between 22° to 32°C (72 to 90˚F) throughout the year. Nights are cool with temperatures between 16 to 21°C (60° to 70°F) warming up towards midday with average temperatures of 30°C ( 86°F) and then cooling off again towards evening. Average monthly rainfall is between 125 – 300 mm (5- 12 inches). Days throughout the year are sunny interspersed with rain. The amount of rain depends on the season. 
Each season in the Amazon offers a very different picture, each beautiful and unique. January until May with February and March being the wettest months. Bursts of rain are followed by sunny periods. Temperatures are cooler at this time of the year averaging 26˚C (79˚F) with temperatures that can go up to 33˚C (93˚F) at mid day. At this time of the year, rivers swell with water and huge tracts of land are swamped. Most naturalists visit the Amazon during this season since the forest is undergoing spectacular changes. There is more fauna activity registered during this period since animals are changing from one location to another. Plants bloom and fruit trees usually bear fruit at this time to take advantage of the high water to spread their seeds. Giant water lilies ( Vitoria amazonica) are present at this time of the year. The higher water levels allow boats to venture deeper into the flooded forests at this time of the year. July to December with August and September being the driest months. Average temperature is 28˚C (82˚F). October is usually the hottest month with temperatures that reach 35˚C (96˚F). Nights, however, remain cool. At this time of the year, rivers are receding as rainfall diminishes concentrating wildlife around less water area. This season is most popular with the “one time” visitor as more animal sightings occur during this period, especially from the boat. Lower water level gives spectacular journeys in lakes and flooded forests and presents white sandy beaches alongside blackwater rivers, ideal for swimming and BBQ’s.
