The climate in Montevideo is characterized as temperate subtropical, with clearly defined seasons. Summer, which lasts from December to March, is usually warm, with average temperatures around 21-24°C, occasionally reaching higher marks. Winter, falling between June and August, is distinguished by its mildness, with average temperatures around 11-12°C, and frost is a rare phenomenon here.

A specific feature of the weather in Montevideo is the distribution of precipitation: it falls relatively evenly throughout the year, without a pronounced dry or rainy season. At the same time, despite the small total amount of rainfall (only 2-3 mm per month according to the provided data), there can be from 7 to 10 rainy days per month. This means that rains here are generally frequent, but light and short-lived. Spring (September-November) and Autumn (April-May) are pleasant transitional seasons with comfortable temperatures, ideal for exploring the city.

The temperature pattern in Montevideo is moderate throughout the year, without sharp extremes. The annual temperature progression is smooth: the hottest months are January, with an average temperature of 23.7°C (minimum 19.4°C, maximum 27.9°C), and February, where the average temperature is 22.9°C (minimum 19.0°C, maximum 26.8°C). The coolest month is July with an average temperature of 11.3°C, when nightly minimums can drop to 8.1°C, and daily maximums reach 14.5°C. Similar figures are observed in June.

The summer months, from December to March, offer residents and guests of Montevideo pleasant warmth. Daytime temperatures during this period usually range from 25°C to nearly 28°C, creating comfortable conditions for walks and relaxing by the coast. Nights bring refreshing coolness, with temperatures dropping on average to 17-19°C. The difference between day and night temperatures in summer is about 8-9 degrees, ensuring comfortable sleep without exhausting humidity.

Winter in Montevideo, covering the period from June to August, is characterized by mild and cool weather. Average daytime temperatures hold in the range of 14-16°C, while night temperatures can drop to 8-9°C. Although frosts happen rarely, a light chill is felt, especially in the morning and evening hours. Fluctuations between day and night temperatures in winter are somewhat smaller than in summer, amounting to approximately 6-7 degrees. The transitional seasons – Spring (September-November) and Autumn (April-May) – are distinguished by gradual temperature changes, offering many comfortable days for exploring the city.

In Montevideo, precipitation is distributed surprisingly evenly throughout the year, and it is difficult to single out a classic "rainy season" or a distinct "dry season" solely based on the amount of falling moisture. A very small amount of precipitation is registered monthly – only from 2 to 3 mm. This suggests that heavy and prolonged downpours are not characteristic of the city.

If we look at the details, one can notice that some months receive slightly more moisture: February, March, April, May, July, and December are characterized by 3 mm of precipitation. At the same time, January, June, August, September, October, and November receive an average of 2 mm. However, this difference of 1 mm is minimal and is practically not felt against the general background.

A more indicative characteristic is the number of "wet days" in a month. The leader in precipitation frequency is March, when it rains for an average of 10 days. Slightly less often, about 9 days, precipitation is observed in July. The lowest number of rainy days – 7 each – falls on April, May, August, September, and December. In the remaining months (January, February, June, October, November), one can expect approximately 8 days with precipitation.

Considering that a small amount of precipitation (2-3 mm) is distributed over 7-10 days, one can conclude that rains in Montevideo are most often light, possibly in the form of drizzle or brief light showers, rather than heavy torrential downpours. Snowfall is uncharacteristic for Montevideo. Thus, although a small umbrella might be a useful accessory on any trip, prolonged periods of inclement weather are unlikely.

When packing your suitcase for a trip to Montevideo, remember its moderate climate with frequent but usually light precipitation throughout the year. The key principle here will be layering. In summer (December-March), you will need light clothing: t-shirts, shorts, dresses, swimwear, as well as a hat and sunglasses, as temperatures can reach a comfortable 28°C. In Spring (September-November) and Autumn (April-May), the weather is pleasant but changeable, so it is worth adding a jumper or cardigan to your light wardrobe. Regardless of the season, bring a light waterproof jacket or a compact umbrella – they will come in handy during unexpected rain or for protection against the refreshing breeze from the Atlantic, which is often felt on the waterfront.

In winter (June-August), it gets cooler in Montevideo, with average temperatures around 8-15°C. At this time, you will need warmer items: sweaters, fleece tops, jeans or thick trousers, as well as a mid-season jacket, a scarf, and possibly a thin hat, especially for evening walks. An indispensable attribute of your journey at any time of the year should be comfortable shoes for long walks around the city. Do not forget sunscreen, which is relevant even on cloudy days due to the proximity to the water, and a small backpack for daily needs to make your excursions as comfortable as possible.
