Sao Jose dos Campos boasts a pleasant climate that can be described as humid subtropical or highland tropical. Thanks to its location, the city avoids the stifling heat common to many other regions of Brazil, and the weather remains comfortable for most of the year. This makes the destination attractive for those seeking a balance between warm days and fresh nights.

Two seasons are clearly distinguished throughout the year: a warm and humid summer, which lasts from December to March, and a cooler, drier winter from June to August. During the summer months, the daytime temperature usually hovers around +26°C...+27°C; however, this time of year is characterized by high humidity and frequent rainfall. Winter brings noticeable coolness, especially during the night hours when the temperature can drop to +11°C, but the days remain predominantly clear and sunny.

When planning a trip, it is important to consider the distinct rainy season. The period from December to February is the wettest, when the number of rainy days can reach 22–25 per month. In contrast, the middle of the year, especially July, is considered the driest time: rain becomes a rarity, falling only a few times a month, creating ideal conditions for long walks and exploring the city.

The climate in Sao Jose dos Campos can be described as mild and pleasant, without extreme heat or harsh cold, making the city comfortable to visit year-round. Since Brazil is located in the Southern Hemisphere, the warmest period here falls in the months from December to March. Summer in this region is moderately hot: the average daily temperature in January and February reaches a maximum of +26…+27°C. Nights in the summer season remain warm and comfortable, with figures around +18…+19°C, allowing you to enjoy evening walks.

The winter season, which lasts from June to August, brings noticeable but not excessive coolness. The coldest month of the year is usually July, with an average temperature of about +17°C. During the day in the winter months, the air still warms up to a pleasant +22…+23°C, however, travellers should be prepared for daily temperature fluctuations. Nights in winter can be quite fresh: the thermometer often drops to +11…+12°C, so it is recommended to bring warm clothes for the evening.

Transitional periods, such as April or October, offer a "happy medium" with daytime temperatures ranging from +21°C to +25°C. In general, the city's annual temperature regime is stable, where even on the hottest days the heat is rarely exhausting, and the winter cool is more invigorating than freezing.

Precipitation in Sao Jose dos Campos has a pronounced seasonal character, which is typical for the climate of this region of Brazil. The year is clearly divided into a wet summer period and a dry winter season. The largest number of rainy days falls in summer: precipitation occurs very frequently from December to March. The record holder is January, when an average of about 25 rainy days is recorded, so travellers at this time of year should always have a raincoat or umbrella with them.

Winter, on the contrary, delights tourists with more stable and clear weather. From June to August, the probability of getting caught in the rain is minimal. July is considered the driest month: at this time, precipitation is a rarity, and on average there are only about 3 rainy days for the entire month. This makes the middle of the year an excellent time for hiking and outdoor excursions.

The transitional periods, spring and autumn, are characterized by a gradual change in weather conditions. Already in October, the number of wet days noticeably increases to 18, and in April, conversely, it decreases to 10. Generally, rains here usually come in the form of warm showers, which are often replaced by sunshine, especially during the hot months.

Packing for Sao Jose dos Campos largely depends on the season you plan to visit. If your trip falls during the summer months (from December to March), be prepared for warm weather, which is often accompanied by precipitation. During this period, light clothing made from natural fabrics will be the best choice, but the most important accessory will be a reliable umbrella or a high-quality raincoat, as it rains very often.

In winter (from June to August), the climate becomes significantly drier but cooler, especially at night when the temperature can drop to 11-12°C. For this time of year, the principle of layering is ideal: take jeans, long-sleeved t-shirts, and a warm sweater or light jacket for evening walks with you. During the day in the sun, it can be warm, so the ability to remove the top layer of clothing will be useful.

Regardless of the travel date, be sure to pack comfortable shoes for long walks in city parks and streets. Also, do not forget about sun protection: even on cloudy days, ultraviolet radiation in Brazil is quite active, so sunscreen and a hat will be useful to you all year round.
