Weather in Tucuruí

Stay up to date with the meteorological conditions when planning to visit Tucuruí. Below are the latest updates, charts, and forecasts to help you better plan your schedule.

The climate in Tucuruí can be described as hot and tropical, typical for this region of Brazil. An eternal summer reigns here: air temperatures remain consistently high throughout the year, with virtually no sharp fluctuations. Travellers should expect a warm atmosphere regardless of the month chosen for the trip, as thermometer readings rarely drop below comfortable levels.

Weather conditions are clearly divided into two distinct seasons: wet and dry. The first half of the year, particularly from January to April, is characterised by high humidity and frequent precipitation — rains can occur almost daily. During this time, the sky is often cloudy, but it is thanks to these rains that the local nature looks particularly lush and green.

From June to November comes the dry season, when the number of rainy days decreases sharply, reaching a minimum in August and September. This is the sunniest period of the year; however, tourists should be prepared for the heat: it is during September and October that the highest temperatures occur, as the air warms up to its maximum values.

The climate in the city of Tucuruí is characterised by consistently high temperatures throughout the year with minimal seasonal variations. The hottest period is observed in September and October, when average readings reach 29.7°C, and the daily maximum often exceeds 33°C. Conventionally "cool" months are February and March, when the average temperature holds at around 26.7°C, which is largely due to the rainy season tempering the heat.

Traditional concepts of winter and summer function differently here than in temperate latitudes. During the Southern Hemisphere's calendar winter (June–August), the weather becomes drier and hotter: the temperature gradually rises from 27.5°C to 29°C. Calendar summer (December–February), conversely, feels slightly milder due to high humidity and cloud cover, keeping daily highs within the 29–30°C range.

Daily temperature variations in this region of Brazil are quite comfortable but do not bring significant cold. During the day, the air reliably warms up to 30–34°C, while at night it cools down only to 24–25°C. Such a slight difference between the daytime heat and night-time temperature means that travellers will hardly need warm clothing even after dark.

Precipitation in Tucuruí is distributed unevenly throughout the year, forming distinct wet and dry seasons. The rainiest period lasts from December to April. During this time, especially in January and March, it rains almost daily — statistics show up to 30 days of rainfall per month, so travellers should be prepared for high humidity.

The dry season arrives in the middle of the year and peaks in August and September. In these months, the probability of getting caught in the rain is minimal: only about 4–5 rainy days are recorded. July and October also delight visitors with a high number of sunshine hours, making this period the most favourable for active outdoor leisure.

Transitional months, such as May and November, demonstrate a gradual change in weather with a moderate amount of precipitation. Despite the difference in rain frequency, the air temperature in this region of Brazil remains high year-round, so even frequent downpours at the beginning of the year feel warm and tropical.

The climate in this region is hot year-round, so the foundation of your wardrobe should be light clothing made from natural breathable fabrics, such as cotton or linen. When setting off for Tucuruí, take t-shirts, shorts, loose trousers, and open footwear. Considering that even at night the temperature rarely drops below +24°C, you will unlikely need warm items, although a light long-sleeved top may be useful for protection against insects in the evening or for premises with strong air conditioning.

When packing, it is critically important to consider the seasonality of rainfall. From January to May, the rainy season prevails, with precipitation occurring almost daily, so be sure to pack a lightweight raincoat or poncho and waterproof, quick-drying shoes; an umbrella may be less practical. Conversely, from June to October, a dry period sets in when rains are extremely rare, and air temperatures can rise to +34°C.

Regardless of the time of year, Brazil requires reliable protection from the sun. Be sure to bring high SPF cream, quality sunglasses, and a wide-brimmed hat to avoid heatstroke. For long walks and excursions, comfortable closed footwear with non-slip soles is most suitable.
