Uruguay's climate has distinct thermal seasons. With a moderate climate, the maximum temperatures during the summer months from December to April rise to 25 to 28 degrees, in the subtropical north even to over 30 degrees. In the coastal regions it is cooler and wetter than in the northwest of Uruguay. In winter, the average temperature reaches a maximum of 15 degrees, but sometimes temperatures can drop below freezing. On average, around 1200 mm of precipitation fall quite evenly throughout the year.
The water temperatures on the Atlantic beaches are between 20 and 22 degrees Celsius in the southern summer. At the same time it gets very hot in the interior, which is why the following autumn months are recommended for a hiking or city holiday.
