What’s the weather like in Mexico in August?

Mexico has a spectacular Caribbean coastline in the east and a lovely North Pacific coast in the west, which does mean there’s differences in weather across the country. The popular Yucatán Peninsula, which forms a divide between the Caribbean Sea and the Gulf of Mexico, will guarantee you plenty of heat and sun in August.

Yucatán Peninsula

The peninsula has a tropical climate that’s similar to large parts of Mexico until you get to the Tropic of Cancer where the climate becomes a bit less extreme. There’s not much difference between summer and winter in popular resorts such as Cancún and Playa del Carmen, although temperatures are at their peak in August.


You’ll find highs of 34ºC in Cancún during August, and things don’t get too much cooler at night, with temperatures only dropping to 23ºC. At 29ºC, the sea’s also really warm, while humidity’s very high. Average rainfall’s 181mm over six rainy days, which tends to be in short and heavy showers. You can expect 13 hours of daylight each day with seven hours of sunshine, and make sure you use plenty of sun cream as UV levels will be extreme. Sunset’s just before 7.30pm at the start of August.

Things to Do

Chichen Itza, an important Mayan city, is on the Yucatán Peninsula, where you can visit interesting temples and the mysterious Kukulcan pyramid on a day trip from Cancún and Playa del Carmen. If it’s too hot to explore then stick to the peninsula’s beautiful white sand beaches before heading out to Cancún’s famous bars and clubs.
