As Manaus is located in the Amazon Rainforest, it lacks the distinct seasons characteristic to temperate regions. Here you will simply find a wet and dry season differing by the frequency and intensity of rainfall. The wet season in Manaus is from December / January to May / June where you can expect about 250 mm of rain per month. The drier season is therefore from May / June to December / January, which experiences about 150 mm of rain per month. When it rains, it usually falls with a distinct pattern beginning in late afternoon and often clears by morning. Over the wet season, however, rain can last for a few days.

Best Time to Visit Manaus
The best time to visit Manaus will depend on what you want to see and will reflect your personality. The wet season means channels and tributaries open up so we can get deeper into the forest to find wildlife. The wet season is also when the forest fruits and blooms, however, the dry season has lower rainfall. For more information, see the best time to visit the Amazon.
