Planning your day in Barra do Garças? Here you will find the most up-to-date weather information, detailed charts, and forecasts to help you better prepare for your trip.

The climate in Barra do Garças can be described as hot tropical with distinct seasonal rainfall. For tourists, this means the weather is clearly divided into two contrasting periods: wet and dry. Overall, it is warm in the city year-round, and even in the "coldest" months, daytime temperatures remain high, creating an atmosphere of eternal summer.

The rainy season usually lasts from October to April. During this time, especially from December to March, precipitation falls frequently, and the number of rainy days can reach 23 days per month. From May to September comes the dry season. This is the ideal time for those who want to avoid downpours: in the middle of the year, especially in June and July, rains almost completely stop, and the sky remains clear and cloudless.

The temperature regime also has its peculiarities. The hottest period is September and October, when the air can warm up to 36°C. At the height of the dry season (June-July), nights become fresher and more pleasant, with temperatures around 17-18°C, creating excellent conditions for evening relaxation after a hot day.

Barra do Garças welcomes travellers with a hot tropical climate, where temperature fluctuations throughout the year are not too great but still have their distinct features. The sultriest period here is not the calendar summer, but the end of the dry winter and the beginning of spring — September and October. At this time, the average temperature rises to 29°C, and daytime highs often reach an impressive 36°C. The "coolest" months are considered June and July, although even then average figures hold at a comfortable mark of around 24°C.

The summer season (from December to March) is characterized by stable warmth and humidity: during the day the air warms up to 30–31°C, and nights remain muggy, with temperatures around 22°C. Winter (from June to August), on the contrary, brings drier weather and a noticeable contrast. Days during this period remain summer-hot with highs above 30°C, however, nights become significantly fresher when the thermometer drops to 17–18°C, offering a pleasant respite from the daytime sun.

Travellers should consider significant daily temperature fluctuations, especially in the dry season. For example, in July and September, the difference between daytime heat and nighttime coolness can be about 14 degrees. This means that despite hot days, a light sweater might be useful for evening walks during winter months. September is the temperature peak before the start of the rainy season, so this month is suitable only for the most heat-loving tourists.

Precipitation in Barra do Garças is distributed extremely unevenly throughout the year, forming two distinct seasons: wet and dry. Since the city is located in the tropical climate zone of Brazil, there is no snow here, and the only type of precipitation is rain. It is important for travellers to consider this schedule, as the character of the weather changes radically depending on the chosen month.

The rainy season usually begins in October and lasts until April. The peak falls on the summer months of the Southern Hemisphere: in January, February, and December, the highest number of rainy days is recorded — about 22–23 per month. During this period, precipitation falls very frequently, although it often takes the character of short but intense tropical downpours that bring welcome freshness.

The dry season arrives in May and continues until September. At this time, rains become a rarity, and in June and July, the probability of precipitation is practically zero. These are the driest months of the year when the sky remains clear for weeks. Transition periods, such as April and October, are characterized by a decrease or gradual increase in the frequency of rains, smoothly preparing nature for the change of season.

A trip to Barra do Garças requires a wardrobe oriented towards a warm and hot climate. The basis of your luggage should be light items made of natural breathable fabrics, such as cotton or linen, since the average temperature throughout the year stays at a comfortable level, and in September and October, the heat can reach +36°C. Be sure to bring a wide-brimmed hat, quality sunglasses, and cream with a high protection factor, as the sun here is very active, especially in the cloudless dry season from May to August.

If your trip is planned for the period from October to April, be prepared for the wet season. In these months, especially from December to February, it rains often (more than 20 days a month), so a compact umbrella or a light raincoat will become indispensable companions. However, given the high temperature even during precipitation, choose waterproof clothing that is well-ventilated. In the dry season (June-July), rains are practically excluded, but nights can be a bit cool — the temperature drops to +17°C, so a light sweater or windbreaker will come in handy for evening walks.

For exploring the city and natural attractions, comfortable shoes are best: sandals for hot days and closed sneakers for long walking routes. Don't forget swimwear to enjoy relaxing by the water. It is also recommended to bring insect repellents, which will be especially relevant in the wet season to protect against insects during walks in nature.
