Climate of Uruguay
Country climate guideUruguay occupies the rolling plain between the Río de la Plata and the South Atlantic in the temperate south of South America, lying entirely between about 30°S and 35°S. There are no mountains of any consequence and no distance from the sea greater than about 300 kilometres, so the climate is a mild, humid, maritime one with gentle seasons. Warm water flowing south past the coast keeps the country free of both frosts and extreme heat, and wind, more than temperature, is the noticeable feature of Uruguayan weather.
Main climate types
The country as a whole fits the humid subtropical group in Köppen terms, meeting a temperate oceanic type in the south-west around Montevideo and the Río de la Plata. The eastern departments and the Cuchilla Grande, a low ridge running north to south, are slightly drier than the coast, while the lowland near the river, which floods seasonally, is the wettest and least well drained part.
Temperatures
Montevideo averages about 12 °C to 13 °C in July, the coldest month, and about 22 °C to 23 °C in January, the warmest. The seasonal range is small for the latitude, and daytime highs rarely go below about 15 °C in winter or above about 30 °C in summer. Frost is very rare, snow has been recorded only twice, and midwinter night lows inland can approach minus 5 °C.
Rainfall
Annual rainfall is roughly 1,000 mm to 1,200 mm, with the wettest ground near the estuary and the driest on the ridges inland, and above 1,400 mm in some years. Rain is spread across the year rather than concentrated in a season, with a tendency for the wettest weather in late winter and spring and drier days in early autumn. Humidity is high for much of the year, and the wind from the estuary, locally the pampero, brings cooler, drier air from the interior after hot spells.
When to go
The summer months from December to March are the classic time, with long warm days and beaches throughout, though the heat can build in January. Autumn and early spring, from March to May and September to October, bring mild temperatures and fewer crowds, which suits the wine regions.
