    Cancun weather August

    What's the weather like in Cancun in August?

    Sitting on Mexico’s Yucatán Peninsula, Cancún is one of the country’s most popular destinations due to its spectacular Caribbean Sea setting. It has a tropical climate with high temperatures all year round and August is the hottest month of the year. Cancún’s location does mean there’s a rainy season from May to October, with September being the wettest month. When it rains though, it’s usually in short and sharp downpours.


    If you like the heat then Cancún’s perfect for you in August. The average high is 34ºC and you won’t need many warm clothes as things stay nice and warm in the evenings. The sea temperatures 29ºC, which is lovely for swimming, while humidity’s very high. There’s 148mm of rain over 13 days, although you can still expect 13 hours of daylight with seven hours of sunshine each day. UV levels will be extreme so sun cream is essential. Sunset’s just before 7.30pm at the start of the month, gradually getting earlier.
