Stay up to date with current weather conditions in the city of Ji-Paraná. Below you will find fresh data, detailed forecasts, and useful charts to help you better plan your time.

The climate of the city of Ji-Paraná can be characterized as hot and tropical, typified by consistently high air temperatures throughout the year. Practically eternal summer reigns here: there are no significant cold spells, and the thermometer during the day confidently stays in the range of +26°C to +34°C. Even at night, the air remains very warm, rarely cooling below +20°C, creating a classic tropical atmosphere.

Instead of the usual change of four seasons, the weather in this region of Brazil is clearly divided into two main periods: wet and dry. The rainy season lasts approximately from November to March, reaching its peak at the beginning of the year when precipitation falls almost daily. At this time, humidity increases significantly, and the surrounding nature becomes particularly lush and green.

The dry season, most pronounced from June to August, represents the complete opposite of the beginning of the year. In July, rains may stop altogether, providing tourists with clear skies and sunny weather. However, it is worth noting that the end of the dry period (September) is often accompanied by the highest temperatures of the year, so travellers who do not tolerate intense heat well should plan their trips with this factor in mind.

The climate in this region is distinguished by stable warmth, so Ji-Paraná is ready to welcome travellers all year round. The annual temperature range here is small: even in the "coolest" months, such as May and June, average figures hold at 26°C. The hottest period traditionally becomes the beginning of spring in the Southern Hemisphere — September, when the average temperature reaches 29.2°C, and the daytime heat can intensify up to 35°C.

An interesting feature of the local climate is the winter months (from June to August), which coincide with the dry season. At this time, the most noticeable fluctuations between day and night temperatures are observed. During the day, thanks to cloudless skies, the air heats up to 31–34°C, however, nights bring pleasant freshness when the thermometer drops to 20–21°C. This creates comfortable conditions for relaxing after a busy day.

In the rainy season, which lasts from November to March, the temperature regime becomes milder and more even. Due to high humidity and cloudiness, the temperature amplitude decreases: during the day the air warms up on average to 29°C, and at night it cools down only to 23°C. During this period, a humid and warm atmosphere typical for the tropics of Brazil reigns in the city without sudden changes.

For travellers planning a trip to this region, it is important to know that Ji-Paraná has a distinct division of the year into wet and dry seasons. The main period of rains falls on the summer months of the Southern Hemisphere and the beginning of autumn. From November to March, precipitation falls very frequently: statistics show that in January and March there can be up to 28 rainy days, so waterproof clothing will be simply essential.

The situation changes radically with the arrival of the calendar winter. The period from June to August is considered the driest time of the year. In July, for example, the probability of precipitation is minimized — often 0 rainy days are recorded for the entire month. This time is excellent for those who want to avoid tropical downpours and enjoy stable weather during walks.

Since the city is located in Brazil, precipitation here falls exclusively in the form of rain; snow does not occur in this hot climate. Even in the wettest months, the temperature remains high, so the rains are usually warm. Transitional months, such as May and September, offer a balance: the number of rainy days decreases to 9, which makes the weather more predictable compared to the beginning of the year.

When preparing for a journey to Ji-Paraná, it is worth orienting yourself towards the hot tropical climate that prevails here all year round. Since the average air temperature consistently stays in the range of +26...+29°C, the foundation of your wardrobe should be light clothing made from natural breathable fabrics, such as cotton or linen. Be sure to take a wide-brimmed hat or cap, sunglasses, and high-factor sunscreen, as the sun in Brazil is very active.

The choice of other items depends on the time of year. From December to March, the rainy season lasts, when precipitation falls almost daily (up to 28 rainy days per month). During this period, a quality raincoat, waterproof shoes, and a sturdy umbrella are vitally necessary. Conversely, from June to August comes the dry season, when rains almost never happen. Although days remain hot, night temperatures can drop to +20°C, so a light cardigan or windbreaker will be useful for evening walks.

For comfortable movement around the city and surroundings, choose comfortable flat shoes or sandals that securely fix the foot. Considering the high humidity in the rainy season and proximity to nature, do not forget to pack repellents for protection against insects. The principle of layering in clothing will be especially relevant in the transitional months (April and November), when the weather can change during the day.
