Weather in Sao Jose do Rio Preto

Planning a trip or just want to know what awaits you on the streets of Sao Jose do Rio Preto? Below you will find the most up-to-date weather information, including detailed forecasts and visual graphs.

The climate in Sao Jose do Rio Preto can be described as tropical, with a distinct division into wet and dry seasons. Overall, the weather here remains warm throughout the year, making the city comfortable to visit at almost any time. Even during the coolest months, the average temperature stays at a pleasant level, allowing tourists to enjoy walks and outdoor activities.

Two distinct periods can be clearly traced during the year. From October to March, the hot and humid season prevails, during which the bulk of precipitation falls, and air temperatures often exceed 30°C. September and October are particularly hot months, preceding the height of the rainy season. During this time, humidity rises, and downpours become a frequent occurrence, bringing temporary freshness.

The second period, from April to September, is considered drier and milder. The winter months (June, July, and August) are characterized by minimal rainfall—rain is extremely rare at this time, and the sky remains clear. Temperatures become more comfortable, dropping to an average of 22°C, although nights can be quite fresh. This is the ideal time for those who prefer to avoid exhausting heat and high humidity.

The climate in Sao Jose do Rio Preto is characterized by high temperatures for most of the year, making this Brazilian city an attractive destination for warmth lovers. Interestingly, the highest temperature values are recorded not in the height of summer, but in early spring: September and October are the hottest months, when the average daily maximum reaches 32–33°C. During this period, the air warms up quite significantly, creating a sultry atmosphere before the start of the rainy season.

The winter period, which lasts from June to August in the Southern Hemisphere, feels like a very mild and pleasant summer in temperate latitudes. In the "coldest" months—June and July—the daytime temperature comfortably holds at around 27–28°C. This time of year is distinguished by aridity and a large number of sunny days, unlike the wet calendar summer (from December to March), when frequent rains are accompanied by stable warmth of around 30°C.

Travelers should pay attention to daily temperature fluctuations, which become especially noticeable during the dry winter season. While the air warms up to summer values during the day, the thermometer can drop to 15–16°C at night. Such a difference between daytime heat and evening freshness requires having light outerwear in your luggage for walks after sunset, whereas in the summer months, the warmth persists around the clock.

In Sao Jose do Rio Preto, there is a pronounced seasonality of precipitation, typical of Brazil's tropical climate. The year is clearly divided into wet and dry periods. The main rainy season falls on the summer months (from December to March). The wettest month is January, when precipitation can occur over 21 days. December and February are also characterized by high humidity—about 19 rainy days in each.

The winter period, on the contrary, is characterized by clear and dry weather. From June to August, rain becomes a rarity. The driest month of the year is considered to be July, when on average only one day with precipitation is recorded. In June and August, the probability of getting caught in the rain is also extremely low (2–3 wet days), making this time comfortable for open-air excursions.

In the transitional seasons, the weather changes quite quickly. While the number of rainy days decreases to six in April, foreshadowing the start of the dry season, by October the frequency of precipitation rises again to 12 days. Precipitation falls exclusively in the form of rain, often in the form of short but intense downpours.

Since the climate in Sao Jose do Rio Preto is predominantly warm, the foundation of your wardrobe should consist of light and breathable items made from natural fabrics, such as cotton or linen. In the hottest months, especially in September and October, when daytime temperatures often exceed 30°C, you will need t-shirts, shorts, and loose dresses. Do not forget reliable sun protection: a wide-brimmed hat or cap, sunglasses, and high SPF cream are mandatory to protect your skin from the intense Brazilian sun.

If your trip is planned for the period from December to March, it is worth preparing for the wet season. During these months, the number of rainy days is high, so a compact umbrella or a light raincoat will become indispensable items in your luggage. Conversely, during the winter period (from June to August), precipitation falls extremely rarely, but evenings can be quite fresh, with temperatures around 16°C. For comfortable walks after sunset at this time of year, it is recommended to take a light jacket, cardigan, or hoodie, using the principle of layering.

For exploring the city's sights, choose comfortable footwear, for example, light sneakers or sandals with good foot support, in which it is comfortable to walk all day. Given the possible humidity during the rainy season, it is useful to have a spare pair of shoes. Tourists are also advised to bring insect repellent, which may come in handy during evening relaxation outdoors or walks in the parks.
