Weather in Bonito

Be prepared for any of nature's surprises during your visit to Bonito. Below, we have gathered the freshest weather data for you, including current readings, forecasts, and visual charts.

The climate in Bonito can be described as tropical, with distinct wet and dry seasons. Overall, the weather here remains warm and favourable for travel year-round, although the nature of the holiday may change depending on the month. Thanks to stable temperatures, the city is an excellent destination for those wishing to enjoy the nature of Brazil without extreme heat or severe cold.

The year is clearly divided into two periods. The summer months (December to March) are the hottest time, when daytime temperatures often exceed 30°C. However, this is also the rainy season: rainfall occurs frequently, and the number of rainy days can reach 18–19 per month. Winter (June to August), conversely, is considered the dry season. It becomes cooler during this time, especially at night when the temperature can drop to 15–16°C, but rain is extremely rare.

It is important for tourists to consider this seasonality when planning activities. During the dry winter period, river water becomes maximally clear, which is ideal for snorkelling and diving, for which the region is famous. The summer period delights with lush vegetation, despite frequent rainfall. Regardless of the season, Bonito offers comfortable conditions: even in the coolest months, the average daytime temperature holds at a pleasant 20–22°C, allowing you to enjoy open-air walks.

The climate in Bonito is favourable for visiting at any time of the year, yet the temperature regime has its seasonal peculiarities. The hottest period falls during the Brazilian summer — from December to February. During these months, the average temperature holds at 27°C, while in the daytime, the air consistently warms up to 31.5°C. Nights at this time of year remain very warm and comfortable, with readings around 22–23°C, which is ideal for evening relaxation after an active day.

The winter months, especially June and July, bring long-awaited freshness and are considered the coolest time of the year. The average temperature drops to 20–21°C, making this period mild but not cold. It is still sufficiently warm during the day (up to 25–26°C), however, tourists should take note of noticeable diurnal fluctuations: nights become cool, and the thermometer can drop to 15–16°C. On such evenings, a light jacket or jumper will be most welcome.

Transitional seasons also have their charm. As early as September, with the arrival of spring, the temperature begins to rise rapidly, reaching daytime highs of 31°C. May, on the other hand, marks a smooth decline in heat before winter, offering travellers comfortable conditions with average values around 22°C. Regardless of the season, Bonito pleases guests with the absence of extreme cold, offering a choice between the tropical heat of summer and the invigorating freshness of winter.

Seasonality of precipitation is clearly expressed in Bonito, characteristic of the tropical climate of this part of Brazil. Since temperatures here remain high year-round, precipitation falls exclusively as rain. The year can be roughly divided into a wet season, falling in summer and early autumn, and a significantly drier winter period.

The wettest time of the year is the beginning of the year. January leads in rainfall frequency: an average of about 19 rainy days is recorded in this month. February and March are also distinguished by high humidity, when it rains for more than half the days of the month. During this period, travellers should be prepared for regular rainfall, which, however, is often warm and short-lived.

The dry season arrives in the middle of the year. July is considered the driest month, when the number of rainy days drops to a minimum — on average about 5 days per month. June and August are also favourable for lovers of clear weather, counting only about 8 days with precipitation. This time is excellent for visiting natural attractions, as the water in the rivers becomes maximally transparent.

In transitional periods, such as April or October, the weather is more changeable. The number of wet days varies from 12 to 14, creating a balance between sunny days and refreshing rains. Overall, even in the wettest months, rains rarely fall continuously, leaving enough time to enjoy the beauties of the region.

For a trip to Bonito, where warm weather reigns for most of the year, the basis of your wardrobe should consist of light items made from natural breathable fabrics, such as cotton or linen. Considering that in the summer months (December to March) the temperature often rises above 30°C and a large number of rainy days are observed (up to 19 days in January), be sure to take a compact raincoat or umbrella with you. Also, since the region is famous for its aquatic attractions, do not forget several sets of swimwear and a quick-drying towel.

If your journey falls during the winter period (June to August), be prepared for contrasts: it can be comfortably warm during the day, but at night the temperature sometimes drops to 15–16°C. In this case, we recommend using the layering principle: take a light jacket, windbreaker, or cosy jumper with you, which can be easily thrown over a t-shirt on a cool evening. This will allow you to feel comfortable throughout the day, regardless of the whims of the weather.

Pay special attention to footwear: for walking on trails and visiting caves, you will need comfortable, worn-in trainers or trekking sandals with non-slip soles. Since the sun in Brazil is active year-round, be sure to pack sun cream with a high protection factor, a hat, and quality sunglasses in your suitcase. A supply of repellents will also not go amiss, as excursions often take place surrounded by wild nature.
