Climate of Uruguay

Where is the country of Uruguay located? Uruguay is a country in southeastern South America, bordering Argentina to the west and Brazil to the north. All of Uruguay has a warm maritime climate with warm summers and very mild winters. Due to its location in the southern hemisphere, these seasons are exactly opposite to those in Europe, making December through February the warmest in Uruguay and June through August the coolest. In the coldest months the maximum temperature is on average around 14-15 degrees, during really cold winters it can get cooler and even frost. The cold record for the capital Montevideo is minus six degrees Celsius. In the summer months the average temperature is 26 to 30 degrees.

Inland it can easily get a little hotter, but along the coast extreme temperatures above 35 degrees are quite rare, because there is almost always a light breeze from the sea that tempers the temperatures. An interesting detail is that it can easily get hotter in the summer in the fairly nearby capital of Argentina, Buenos Aires.


Wind is an important factor for Uruguay’s climate. In the summer months the wind blows mainly from the ocean, so it does not get too hot, in winter polar winds from the south can provide relatively cool periods and in spring and autumn the wind currents at high altitudes often cause a sudden change in the weather. Because the wind direction can change just like that at many kilometers altitude, the temperature and the weather can differ enormously within 24 hours. This unpredictability makes it difficult to come up with a good weather forecast for Uruguay in the spring and autumn.


Uruguay has no rainy season or dry period. Precipitation falls fairly evenly over the year, with no clear peaks up or down if you look at the long-term average precipitation figures. Winter is slightly wetter in the far east, summer is slightly wetter in the north. The annual average amount of precipitation is between 900 and 1235 millimeters. It almost always involves rain; snowfall is uncommon in Uruguay. This is mainly because the really cold air is often dry air, so that any frost is rarely accompanied by precipitation.
