Manaus

Manaus is the capital of Amazonas state and the largest city in the Brazilian Amazon, sitting at the confluence of the Rio Negro and Rio Solimoes where they form the Amazon River proper. Founded in 1669 as a Portuguese fort, it exploded into one of the wealthiest cities on Earth during the rubber boom of 1880-1910, an era that left behind the Teatro Amazonas opera house and a historic center of Belle Epoque architecture. Today it is home to 2.2 million people and serves as the primary gateway for travelers heading into the Amazon rainforest. Its climate is equatorial: hot, humid, and rainy year-round, with temperatures locked between 23°C and 33°C (73-91°F) and annual rainfall exceeding 2,300mm (91 inches). What changes through the year is not the temperature but the volume of rain and the level of the rivers, which rise and fall by 10-15 meters between wet and dry seasons, transforming the landscape and dictating what activities are possible.

Manaus Weather at a Glance

Manaus has a tropical rainforest climate (Koppen Af) with no winter or summer: every month averages between 30°C and 33°C (86-91°F) for highs and 23-24°C (73-75°F) for lows. The difference between the hottest month (September, 33°C/91°F) and the coolest (February/March, 30°C/86°F) is just 3°C. What defines the seasons is rainfall. The wet season runs from December through May, with March typically being the wettest month at 310mm (12.2 in) over 25 rainy days. The dry season runs from June through November, with August the driest at just 70mm (2.8 in) over 10 rainy days. Humidity stays between 77% (August) and 86% (February-March) year-round. Sunshine ranges from 3.5 hours per day in February-March to 7 hours in August. For the full month-by-month climate data, see the Manaus weather by month guide.

Seasonal Snapshot

• Wet Season (December to May): Daily afternoon downpours, highest humidity (83-86%), lowest sunshine (3.5-5 hours). Rivers rise 10-15 meters, submerging forest trails. This is the best period for flooded forest (igapo) canoe excursions and the Festival Amazonas de Opera (April-May). Hotel prices are lower, especially March-April.
• Dry Season (June to November): Rainfall drops to 70-135mm/month, humidity falls to 77-81%, and sunshine reaches 7 hours/day in August. River beaches like Ponta Negra expand dramatically. Forest hiking trails are in their best condition. This is peak season for jungle lodges and river cruises. The Festival de Parintins (late June) and Boi Manaus (October) happen during this period.

Location and Climate Context

Manaus sits at 3 degrees 6 minutes south latitude, roughly 1,500km (930 miles) inland from the Atlantic coast, deep in the Amazon basin. The city is surrounded by rainforest on all sides: there are no roads connecting Manaus to the rest of Brazil. The only ways in are by air or by river boat (a 4-5 day journey from Belem at the Amazon’s mouth). This geographic isolation explains why Manaus developed as a distinct urban island in the rainforest, with a unique culture blending indigenous Amazonian, Portuguese colonial, and rubber-boom European influences. The equatorial location means the sun is overhead twice a year (late March and mid-September), and day length varies by only about 20 minutes across the entire year: roughly 12 hours of daylight every day.

The climate is dominated by the Intertropical Convergence Zone (ITCZ), a band of convective thunderstorms that migrates north and south of the equator with the seasons. When the ITCZ passes directly over Manaus (March-April), rainfall peaks. The city also experiences friagem events: occasional cold fronts from the south that can push temperatures down to 18-20°C (64-68°F) for a day or two, usually between June and August. These are rare and brief but notable in a place where the normal low is 23°C (73°F).
