Quick verdict
Peak season: Jun–Nov. Shoulder: May, Dec. Low: Jan–Apr.
Manaus has an equatorial climate — hot and humid year-round, with a less-rainy "dry" season (June-November) and a serious wet season (December-May) that takes the river up by 10-12 metres.
What's the weather like in Manaus by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Manaus during Jun–Nov?
Rains tapering off, river starting to drop. Comfortable balance — still some rainforest immersion, beginning of the better wildlife-spotting season.
Shoulder season (May, Dec) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Apr) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
What festivals and events happen in Manaus?
- Festival de Parintins (Boi-Bumbá)Last weekend of June
The biggest festival in northern Brazil — held on Parintins island 370 km downstream of Manaus, three days of giant-puppet folk theatre and competitive samba between two rival "Bois" (Boi Garantido red, Boi Caprichoso blue). Charter flights and riverboats from Manaus; hotels on Parintins triple in price. The most authentically Amazonian festival in Brazil.
- CarnivalFebruary or early March
Manaus celebrates with smaller-scale street parades and indoor balls than Rio or Salvador, with strong Boi-Bumbá folk influence. Pleasant rather than overwhelming; cheaper than the big-city carnivals.
- Festival Amazonas de ÓperaApril - May
The Teatro Amazonas opera season — international productions in the rubber-boom theatre, with tickets from R$30-150. The single most magical context for opera anywhere in South America.
- Round of Sailings (Festival de Cirandas)August
The traditional ciranda folk dances are performed by communities along the river — a quieter, more local festival than Parintins, accessible from Manaus by short boat trips.

Frequently asked
When is the best time to visit Manaus?
The best time to visit Manaus is Jun–Nov. Manaus has an equatorial climate — hot and humid year-round, with a less-rainy "dry" season (June-November) and a serious wet season (December-May) that takes the river up by 10-12 metres.

When is the cheapest time to visit Manaus?
Low-season months in Manaus run Jan–Apr. Flights and hotels typically run 20-40% cheaper than peak. The trade-off is weather (which is why these months are off-peak) and some businesses operating shorter hours, especially in smaller seasonal destinations.
What's the weather like in Manaus year-round?
Summer averages around 31°C (88°F) and winter averages around 26°C (79°F) in Manaus. Manaus has an equatorial climate — hot and humid year-round, with a less-rainy "dry" season (June-November) and a serious wet season (December-May) that takes the river up by 10-12 metres. Temperatures barely vary across seasons (around 28-32°C daytime, 23-26°C nights). The river level dictates the trip experience: low water (Sep-Nov) means more wildlife concentrated near remaining channels, river beaches exposed, and easier hiking; high water (Apr-Jun) means flooded forest (igapó), boat access deep into the canopy, and more aquatic life. Dry-season visits give you better wildlife sightings; wet-season visits give you more spectacular forest immersion.
