The climate of Santa Maria in Brazil is characterised by distinct seasons. Summer, lasting roughly from December to March, is warm here: the average air temperature often exceeds 25°C, while maximum values reach about 30°C. Winter, falling in June-August, is noticeably cooler and mild, with average temperatures around 14-15°C and minimum values dropping to about 10°C. Such a change of seasons offers diverse experiences depending on the time of your visit.

One of the remarkable features of the weather in Santa Maria is the nature of the precipitation. Although rainy days occur quite regularly throughout the year (approximately from 9 to 13 days per month), the total amount of precipitation remains consistently low, usually amounting to 3 to 6 millimetres per month. This suggests that while you may encounter frequent but light rains, heavy downpours are rare here, and the climate generally leans towards the drier side, despite the regularity of wet days. A clearly defined rainy or dry season, in terms of precipitation volume, is not observed; rather, it is a steady pattern of light precipitation.

The city of Santa Maria experiences a distinct annual temperature progression typical of a subtropical climate. The hottest month is usually January, when the average air temperature reaches 25.1°C. During this time, daytime highs often rise to 30.1°C, while nighttime temperatures drop on average to 20.2°C. The coolest month is considered to be July, with an average temperature of 14.4°C. During the day, the thermometer in July shows about 19.0°C, and at night it can drop to 9.8°C.

The summer period in Santa Maria, which falls on the months from December to March, is distinguished by warm, and at times hot weather. Average daytime temperatures during this time range from 28.1°C in March to 30.1°C in January. Nights remain warm, with average minimum temperatures from 18.2°C to 20.2°C. Winter, from June to August, brings mild and moderately cool weather. Average daytime temperatures during these months stay in the range of 19.0°C - 20.6°C, while nights become noticeably fresher, with average minimum values from 9.8°C in July to 11.1°C in June.

Throughout the year in Santa Maria, significant diurnal temperature fluctuations are noted. The difference between the maximum daytime and minimum nighttime temperature is often about 9-10°C. For example, in January this range is almost 10°C (from 20.2°C to 30.1°C), and in July – about 9°C (from 9.8°C to 19.0°C). This means that even after a hot summer day, the evening can bring pleasant coolness, and in winter, despite relatively warm days, nights can be quite cold, requiring appropriate clothing.

In the city of Santa Maria, precipitation falls throughout the year, however, its total amount is small, indicating the absence of a clearly defined season of torrential rains or prolonged drought. Rather, it is a matter of periodic, often light precipitation distributed over the months. In general, the climate can be characterised as sufficiently wet in terms of precipitation frequency, but not by its volume.

The greatest amount of precipitation, about 6 mm, usually falls in May and September. In these same months, as well as in January, the maximum number of days with precipitation is also observed – approximately 13 days in January and September, and 12 days in May. This suggests that rains occur more often during these periods, although their intensity, judging by the total volume, remains low.

The least amount of precipitation, about 3 mm per month, is characteristic of July, August, and December. During these periods, the number of rainy days also decreases, averaging from 9 to 10 days. Given the climate of Santa Maria and positive average monthly temperatures year-round, all precipitation falls in the form of rain. Snow is atypical for this region.

When planning a trip to Santa Maria, it is important to consider weather conditions that change throughout the year. Summer (from December to March) is warm here, with average temperatures around 23-25°C and maximums reaching 30°C. For this period, light, breathable clothing made from natural fabrics is ideal: T-shirts, shorts, sundresses. Do not forget sunscreen, a hat, and sunglasses. Despite the small amount of precipitation (3-5 mm per month), rainy days happen quite often (10-13 days per month), so a light umbrella or raincoat may come in handy.

Winter months (from May to August) in Santa Maria are noticeably cooler, with average temperatures of 14-16°C and minimums dropping to 10°C. At this time, you will need warmer items: jeans or trousers, sweaters, fleece tops, and a light jacket or windbreaker, especially for evening walks. The principle of layering in clothing will be very appropriate here, allowing you to adapt to temperature changes during the day. Although there is little precipitation, the number of rainy days remains stable, so waterproof shoes and an umbrella will not be superfluous.

Regardless of the season, comfortable shoes will always be useful for walking around Santa Maria. Transitional seasons, such as spring (September-November) and autumn (April-May), are characterised by moderate temperatures, so layered clothing is also relevant here. A light scarf and closed shoes can add comfort on cool days or evenings. A small bag or backpack for day excursions, where you can put a bottle of water, sunscreen, and a raincoat, will make your trip more comfortable.
