Uruguay Weather & Climate: Monthly Averages

Uruguay has a warm maritime climate with hot summers and very mild winters. Rainfall is evenly distributed throughout the year. Due to its location in the southern hemisphere, the seasons are exactly opposite to those in Europe, making December through February the warmest in Uruguay and June through August the coolest.

Temperature Ranges

Temperatures rarely fall below freezing and range from 10°C (50°F) to 16°C (61°F) during the day in winter. During summer (December to March), temperatures range from 21°C (70°F) to 30°C (86°F). Inland, it can get a little hotter quite easily, but along the coast, extreme temperatures above 35°C (95°F) are rare.

Impact of Wind and Weather Hazards

An important factor for Uruguay's climate is wind. During summer months, the wind blows almost constantly from the ocean, keeping it from getting too hot. During winter, polar winds from a southerly direction can provide relatively cool periods. Uruguay can also suffer from several natural weather hazards, including floods and droughts. It also occasionally experiences the pampero, a cold and sometimes violent wind that blows north from the Argentine pampas.

Best Time to Visit

The best travel time for Uruguay is generally from November through March. This includes the summer season along with the transition months of November and March. Those who want to travel around Uruguay may want to avoid the hottest months of January and February. In terms of precipitation, it does not matter much when you travel to Uruguay, as rain falls fairly evenly throughout the year. However, during summer months, rain showers are more likely to be stronger and accompanied by thunderstorms.
