When to Go
Between October and March the temperatures are pleasant—it's warm and the country is in bloom. Unless you're prepared to tangle with the multitude of tourists that overwhelm Punta del Este in January and February, late spring (November–December) and late winter (March) are the most appealing months to lounge on the beach.
Uruguay's climate has four distinct seasons. Summer (January–March) can be hot and humid, with temperatures as high as 90°F. Fall (April–June) is marked by warm days and evenings cool enough for a light sweater. Winter (July–September) is cold and rainy, with average temperatures generally below 50°F. Although it seldom reaches freezing, the wind off the water can give you quite a chill. Spring (October–December) is much like the fall, except that the trees will be sprouting, rather than dropping, their leaves.
