Weather in Parintins

Planning a trip to Parintins? Check out the current meteorological summary, detailed charts, and weather forecast to ensure your trip goes perfectly.

The climate in Parintins can be described as hot and tropical, with high humidity and consistently warm temperatures throughout the year. An atmosphere of eternal summer reigns here: the average air temperature fluctuates within the comfortable range of 27–29°C, while nights bring only slight coolness, rarely dropping below 24°C.

Throughout the year, the weather is clearly divided into wet and relatively dry seasons. The first half of the year, especially from January to May, is characterized by heavy rainfall: it rains almost daily, refreshing the region's lush nature. Starting in June, rainfall intensity decreases, and by August-September, the driest and hottest weather sets in, with daytime temperatures often exceeding 33°C.

Travelers heading to this colourful corner of Brazil can expect plenty of sun and warmth regardless of the travel month. However, even during the "dry" season, tropical downpours are possible, so an umbrella or raincoat will be useful companions alongside sunscreen.

The climate in Parintins is distinguished by enviable consistency and high temperatures throughout the year, which is typical for the equatorial latitudes of Brazil. It almost never gets cold here: annual fluctuations are minimal. According to statistics, the hottest month is September, with an average temperature of 29.7°C and daytime highs reaching 33.2°C. The "coolest" period falls at the beginning of the year, in January and February, yet even then, the average temperature remains a comfortable 26.8°C.

Traditional concepts of seasons are blurred here. During the calendar winter months (June-August), the weather remains truly summery: by August, the air warms up to 32.2°C, and the number of rainy days decreases. The summer period (December-February), conversely, brings slightly more moderate heat with daytime highs around 29-30°C, accompanied by high humidity and frequent rainfall. This creates an atmosphere of humid tropical heat, which is easier to bear thanks to the cloud cover.

Daily temperature fluctuations in Parintins are small, so tourists are unlikely to need warm clothes. The difference between the daily maximum and nightly minimum is usually only 5–7 degrees. Nights here are very warm and sultry: even during the "coldest" pre-dawn hours, the thermometer rarely drops below 24.3°C, while in the warmer season, the night temperature holds steady around 26°C.

In Parintins, located in the heart of the Brazilian Amazon, precipitation patterns are directly dependent on the tropical climate. The year here is clearly divided into a wetter and a relatively dry season. The first half of the year, especially from January to May, is characterized by a high frequency of rains. During this period, precipitation can occur almost daily: statistics show that up to 29 rainy days per month are recorded in March, April, and May.

From June, the amount of precipitation begins to gradually decrease, marking the transition to a drier season. The most favourable months for those who prefer clear weather are August and September. At this time, the number of days with precipitation is minimal — only about 8–9 days per month, and the total level of rainfall reaches its lowest values (about 2 mm).

Towards the end of the year, starting in November and especially in December, the rainy season comes into its own again, increasing the number of wet days to 26. Given the consistently high temperatures year-round (about 27–29°C), precipitation here falls exclusively in the form of warm tropical rains, which are often short-lived but refreshing.

Since Parintins is located in a region with a hot tropical climate, the basis of your luggage should be light and loose clothing made from natural breathable fabrics, such as cotton or linen. Throughout the year, daytime temperatures here hover around +27…+30 °C, and can reach even higher marks from August to October. Therefore, t-shirts, shorts, summer dresses, and open-toed shoes will be the most essential items for your trip.

Particular attention should be paid to rain protection, as precipitation occurs frequently here. In the period from December to May, the number of rainy days is at its maximum (up to 29 days per month), so be sure to pack a compact umbrella or a high-quality raincoat in your suitcase. Footwear should be comfortable for walking and, preferably, quick-drying or waterproof so that a sudden downpour does not spoil your walk.

Despite the high humidity and cloudiness, the sun in Brazil is very active, especially during the drier season from August to November. Don't forget to bring high SPF sunscreen, sunglasses, and a wide-brimmed hat. It is also recommended to have a light sweater or windbreaker with you: it will come in handy during river boat trips, where it can be breezy, or in rooms with strong air conditioning.
