Punta del Este in August

December through March brings summer crowds and $300 hotel rooms. January peaks with Argentine vacationers fleeing Buenos Aires heat. Temperatures hit 80°F, perfect for beach days that stretch until 9pm sunsets. April and November offer shoulder season sweet spots. Weather stays pleasant around 70°F, but beach clubs close and some restaurants reduce hours. Hotel prices drop 40-50%. Winter (June-September) sees temperatures around 50-60°F. Many beach-focused businesses shut down completely. But art galleries stay open, and you'll have restaurants to yourself. Perfect for couples seeking quiet romantic walks. March brings the best balance. Summer weather continues but crowds thin as Argentine school starts. Restaurant reservations become possible again.
