The climate in São João del-Rei is characterized as tropical highland, which ensures comfortable weather conditions throughout the year. Thanks to its location, the city rarely experiences sweltering heat, and average air temperatures vary gently from a moderate 17°C in the coolest months to a pleasant 22–23°C at the height of the warm season. This makes the city an excellent destination for those who prefer to avoid temperature extremes.

Two distinct seasons are observed throughout the year, differing less in temperature and more in rainfall. The period from October to March is considered the wet season: the weather is warm but rainy, and in January and December, precipitation can occur on more than 20 days per month. From April, the rains begin to recede, giving way to the dry season, which lasts until September.

For travelers, the most notable weather phenomenon is the winter dry spell (June–August), when the rain almost completely stops and rainy days are kept to a minimum (1–2 days per month). During this time, the air becomes crisp and clear, and nights can be quite cool with temperatures around 11–12°C. This is the ideal time for long walks and sightseeing under clear skies.

The climate in São João del-Rei can be described as moderately warm and comfortable for travel year-round. The hottest period is from September to March, when daytime highs regularly reach +26…+27°C. September is particularly notable, often showing the highest peak temperatures before the main rainy season begins. During the summer months (December, January, February), the weather remains warm, with averages around +22°C, allowing you to enjoy sightseeing without exhausting heat.

The winter season, which in Brazil lasts from June to August, brings a noticeable coolness but remains mild compared to European winters. During this time, the average air temperature drops to +17…+18°C. This is the driest period of the year, when the rain practically stops and the days are clear and sunny. Daytime temperatures in the winter months remain pleasant, often rising to +22…+24°C, creating ideal conditions for walking tours.

A characteristic feature of the local temperature regime is the significant diurnal variations, which are especially noticeable in winter and early spring. The difference between the daytime maximum and nighttime minimum can exceed 10–12 degrees. For example, in July, after a comfortable day with temperatures around +23°C, the air can cool down to +11°C at night. Therefore, when planning a trip during this time, travelers are recommended to carry warm clothes for evening outings.

São João del-Rei experiences distinct seasonal rainfall patterns typical of this region of Brazil. The year is clearly divided into wet and dry periods. The rainiest time is summer (December, January, and February), when humidity peaks. During these months, rain is very frequent: January and December average 22 rainy days each, so travelers should be prepared for regular downpours.

Conversely, the winter period brings dry and clear weather. From June to August, precipitation drops to a minimum. July is considered the driest month of the year: statistics show an almost complete absence of rainfall, with only one rainy day throughout the entire month. This is a great time for those who prefer exploring urban architecture without worrying about getting soaked.

The transitional seasons show a gradual change in weather conditions. In autumn, the number of wet days decreases rapidly: while March still sees frequent rain (about 16 days), by May, this number drops to 4 days. In spring, starting from September, rainfall frequency begins to rise again, preparing the city for the wet summer.

A trip to São João del-Rei requires a well-thought-out wardrobe, especially considering the city's historic character and its cobblestone streets. Be sure to bring comfortable, broken-in flat shoes for long walks. If you are planning a trip during the summer season (December to March), be prepared for frequent rainfall: during this time, it rains more than 20 days a month. Lightweight breathable clothing, a compact umbrella, and a high-quality raincoat will be your best companions, allowing you to explore the city comfortably even in wet weather.

For a trip during the dry winter period (June to August), it’s best to stick to the layering principle. During the day, the weather remains pleasant and warm (up to +23°C), but nights become quite cool, and temperatures can drop to +11°C. During this season, you’ll find t-shirts useful for daytime excursions, as well as a warm sweater, hoodie, or light jacket for evening outings. Regardless of the time of year, don’t forget to pack sunscreen and a hat, as the sun remains strong even on cooler days.
