Planning a trip or simply want to know what awaits you outside? In this section, you will find the most up-to-date information on the weather in the city of Uruguaiana, including the latest forecasts and clear charts.

The climate in the city of Uruguaiana can be characterised as humid subtropical, which is typical for the southern region of Brazil. The weather here features a clear division into seasons, offering travellers a noticeable variety of temperature regimes. Unlike the tropical areas of the country, there is no constant heat year-round here; instead, conditions transition smoothly from sweltering summers to relatively cool winters.

The summer period, lasting from December to March, brings high temperatures: during the day, the air often warms up above 30°C, creating an atmosphere of true southern heat. Winter, occurring from June to August, is conversely mild and fresh. During this time, the average temperature stays around 15°C, while nights can be cool, dropping to 10-11°C, which is worth considering when planning your wardrobe for the trip.

Rainfall is distributed relatively evenly throughout the year, without extreme fluctuations between dry and wet periods. On average, each month sees between 6 to 11 days of precipitation, so a slight chance of rain remains at any time of year. Nevertheless, such stability makes the city accessible and comfortable to visit in practically any month, as the weather rarely brings unpleasant surprises.

The climate in Uruguaiana is characterised by distinct seasonality, offering travellers diverse weather conditions depending on the time of year. Summer, which lasts from December to February in the Southern Hemisphere, is truly hot here. The sweltering month is traditionally January, when the daytime temperature averages 31.8°C, and sometimes even higher. Summer nights remain very warm, with figures around 20-22°C, creating an atmosphere of tropical heat.

The winter months (June, July, and August) bring a noticeable drop in temperature, although the weather remains quite mild and far from extreme freezing. July is considered the coldest month: the average temperature drops to 14.9°C. During the day, the air usually warms up to 19°C, but nights become quite cool, and the thermometer can fall to 10-11°C. Tourists visiting the city in winter should definitely include warm clothes in their wardrobe for evening walks.

A characteristic feature of the local climate is the tangible temperature difference between day and night, averaging about 10 degrees. This feels especially comfortable during the transitional seasons—spring and autumn. For instance, in April and October, daytime temperatures stay at pleasant levels of 25-26°C, while by night the air cools to 15-17°C, ensuring freshness and comfortable conditions for sleep after an active day.

Precipitation in Uruguaiana is distributed quite evenly throughout the year, so travellers should be prepared for changeable weather in any season. It is difficult to single out a clearly defined dry period or a season of prolonged downpours here, although the frequency of rainy days varies slightly from month to month. Given the region's warm climate, precipitation here falls exclusively as rain.

The highest probability of getting caught in the rain exists in the summer months (which occur at the beginning of the year in the Southern Hemisphere) and in early autumn. The "wettest" month in terms of inclement days is considered January, when an average of about 11 days with precipitation is recorded. March is also notable for an increased frequency of rain—around 10 days per month.

The winter period, especially June and July, can be called a relatively dry time of year. During these months, the number of rainy days drops to a minimum—averaging about 6 days per month. Nevertheless, even during this period, the rains do not cease completely, so a light raincoat or umbrella would not be amiss in a tourist's luggage.

When preparing for a trip to Uruguaiana, it is important to consider seasonality, as the climate here changes throughout the year. For the hot summer months (December to February), when temperatures often rise above 30°C, opt for light clothing made from natural fabrics such as cotton or linen. Be sure to bring a hat, sunglasses, and high SPF cream to protect yourself from the strong sun.

If your trip is planned for the winter period (June to August), be prepared for cool weather: during the day the air warms up to an average of 15–20°C, but nights can be fresh, with temperatures around 10°C. The principle of layering works best at this time of year: pack jeans, long-sleeved t-shirts, a warm sweater, and a light jacket or windbreaker for evening walks.

Regardless of the time of year, you will need comfortable flat shoes suitable for long walks for city excursions. Since light precipitation is possible in any month, it is wise to bring a compact umbrella or raincoat. This will allow you to feel comfortable in any weather and enjoy the city's atmosphere without hindrance.
