The hottest season is the Southern Hemisphere summer — from December to February. During this time, especially in January, daytime temperatures reach their peak, rising to an average of 28.8°C. This is an excellent time for active tourism, as the weather is warm but generally lacks exhausting heat.

The winter months (June, July, and August) bring a noticeable chill, but they can't be called harsh. The coldest month is July, when the average temperature drops to 11.9°C, and at night the air can cool down to 7.7°C. During the day, the thermometer usually stays around 16°C. Travelers planning a trip during this period are recommended to bring warm clothes, as evenings and nights can be quite brisk.

A characteristic feature of the temperature regime in Treinta y Tres is the significant difference between daytime and nighttime figures. Throughout the year, the amplitude of fluctuations is about 8–10 degrees. For example, even in the warmest summer months, the nighttime temperature drops to a comfortable 18°C, providing a pleasant freshness after a sunny day.

When planning a trip to Treinta y Tres, it's worth noting that precipitation in this region of Uruguay is distributed quite evenly throughout the year. It’s hard to single out a distinct rainy season or dry period, so a light raincoat or umbrella can be useful in any season. However, rain generally does not pose a serious obstacle to tourism.

According to statistics, precipitation occurs most frequently during the height of the southern summer. The "wettest" month in terms of rainy days is January — during this time, it can rain for about 12 days a month. A slight increase in the frequency of precipitation is also observed in September (around 10 days). During these warm periods, the rain is often refreshing in nature.

During the rest of the year, including the winter months (from June to August), the number of rainy days slightly decreases and stays at around 8–9 days per month. Since the air temperature even in the coldest month, July, averages above 7°C, precipitation occurs exclusively in the form of rain. Snow is not typical for this region, so winter trips proceed without extreme weather conditions.

When planning a trip to Treinta y Tres, it's important to consider the seasonality, as the climate changes throughout the year. If your trip falls during the summer months (December to February), when temperatures reach a comfortable +24...+28°C, opt for light clothing made from natural fabrics like cotton or linen. Be sure to pack a hat, sunglasses, and high-SPF sunscreen to protect yourself from the strong Uruguayan sun. However, even in summer, evenings can be cool, so a light sweater or windbreaker will come in handy.

For a trip during the winter period (June to August), when temperatures drop to +8...+12°C, you'll need a warmer wardrobe. It's best to use a layering approach: a combination of a T-shirt, a warm sweater, and a mid-season jacket will keep you comfortable during temperature shifts throughout the day. Don't forget to bring comfortable jeans or trousers, as well as closed-toe shoes suitable for long walks.

Regardless of the time of year, comfortable walking shoes are a must on your list, as exploring the city and its surroundings involves plenty of walking. Given that rainy days occur regularly throughout the year (averaging 8–12 days per month), it is highly recommended to bring a compact umbrella or a quality raincoat. This will help you continue your excursions even if the weather suddenly turns.
