Cancun enjoys a warm, tropical climate all year round. It is washed by the Caribbean Sea, where the water temperature hardly ever drops below +24°C.
The warmest temperatures in the Caribbean Sea are during the summer months. During this period, it reaches +30°C. Even as night falls and the rainy season begins, the temperature of the Caribbean Sea remains warm. This is due to the tropical current that flows here.
The only thing that can prevent a tourist from swimming here is the waves. However, they only rage in the western part of the Yucatan Peninsula. The northern part of the Yucatan is quiet and calm.
