Thus, Belo Horizonte offers travellers a warm climate with a predictable alternation of wet and dry seasons. This allows you to plan your trip depending on your preferences: either enjoy the sunny days of the cooler and drier local winter (June-August) or experience the warmth of the humid summer with its frequent rainfall (December-February).

The climate in Belo Horizonte is distinguished by warmth throughout the year, but with noticeable seasonal temperature fluctuations. The annual range of average temperatures extends from approximately 18.1°C in July (the coldest month) to 23.5°C in October (one of the hottest months). The hottest months, when daily highs regularly reach 27-28.5°C, are considered to be from September to March, with October and January often showing peak average temperatures. The coolest period falls during the winter months of the Southern Hemisphere, from June to August, where July demonstrates the lowest average temperatures, and minimum nighttime temperatures can drop to 12.1°C.

Average daytime temperatures during this period hover around 27-28°C, while nights remain warm, with temperatures rarely dropping below 18-19°C. The winter months (from May to August) bring milder and, importantly, drier weather. Days during this time remain pleasantly warm, with average highs around 24-25.6°C, however, nights become significantly cooler, and the temperature can drop to 12-14°C.

In Belo Horizonte, there is a distinct seasonality in the distribution of precipitation throughout the year. The city's climate implies that precipitation falls predominantly in the form of rain; snow here is an extremely rare, if not impossible phenomenon, given the average monthly temperatures.

A distinct rainy season in Belo Horizonte usually falls within the period from October to March. The greatest amount of precipitation and rainy days is concentrated from December to February. For example, in January and February, an average of 7 mm of precipitation falls, while the number of rainy days is 18 and 19 respectively. December is also one of the wettest months, with 6 mm of precipitation and approximately 21 rainy days. November and October precede the peak of the rainy season, having 17 and 14 rainy days respectively, but with a slightly lower total volume of precipitation. The nature of precipitation during this period, judging by the number of rainy days with a moderate volume of rainfall, may include frequent but not always intense rains.

The dry season sets in roughly from April to September. During this time, the probability of rain decreases significantly. The driest months are June and July, when the average monthly rainfall is 0 mm. In July, as a rule, there is not a single rainy day, and in June — only one. August is also very dry, with zero precipitation and just two rainy days on average. April, May, and September can be considered transitional months to or from the dry season, with minimal rainfall (1 mm) and a small number of rainy days (from 3 to 9).

When planning a trip to Belo Horizonte, it is important to consider its tropical climate with distinct dry and wet seasons. Warm weather prevails throughout the year, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. T-shirts, shorts, skirts, and light trousers will be appropriate. From November to March, especially in January, February, and December, the rainy season arrives, characterised by frequent, though usually short, downpours. During this period, do not forget to take a compact umbrella or a light waterproof jacket with you. Regardless of the season, high SPF sunscreen, a hat, and sunglasses are mandatory attributes for protection against the bright Brazilian sun.

From May to August, drier and cooler weather sets in Belo Horizonte, especially in the evenings and mornings when the temperature can drop to 12-14°C. In these months, particularly in June and July when rainfall is minimal, a light jacket, sweater, or cardigan will come in handy for comfortable evening walks. The principle of layering in clothing will be very useful, allowing you to easily adapt to temperature changes throughout the day. Comfortable walking shoes are another important item on your list, as the city is hilly, and you will likely want to walk a lot while exploring its attractions.
