Uruguay Weather, climate and geography

Weather & climate

Best time to visit

Uruguay has an exceptionally fine temperate climate, with mild summers and winters. Summer is from December to March and is the most pleasant time, especially along the coast. Beach resorts get crowded between Christmas and February, with peak crowds during the month of January. In the interior and along the Río Uruguay, January is the hottest month, with temperatures sometimes climbing uncomfortably above 30˚C (86°F). For fine weather and quieter conditions countrywide, December and March are good months to visit. Winter and spring can get chilly due to wind and rain, but temperatures remain dependably above freezing.


Uruguay is bordered to the north by Brazil, to the southeast by the Atlantic, and is separated from Argentina in the west and south by the River Uruguay, which widens out into the Rio de la Plata estuary. The landscape is made up of hilly meadows broken by streams and rivers. There are a string of beaches along the coast. Most of the country is grazing land for sheep and cattle. Montevideo, the most southern point of the nation, accommodates nearly half of the population. About 90% of the land is suitable for agriculture, although only 12% is used in this way.
