Cancun weather in August – what to expect

When it comes to weather, Cancun is quite hot during August. But the overcast days and humidity are the reason it feels hotter than it really is.

It’s also the time when Hurricane Season is halfway gone, but don’t worry about any hurricanes; it’s been decades since the last one hit Cancun. Even Grace who has just passed by didn’t do much damage.

Despite the mildly hotter temperatures and more rainy days, families find August as their favorite month to visit Cancun.

With a moderate number of tourists around this time of the year, the prices for hotels and lodgings are manageable, overcrowding isn’t a thing, and the beaches and cenotes are brimming with aquatic life.

The number of rainy days rises when temperatures drop, especially toward the end of the month. But when it does rain on a given day, it usually only lasts an hour or two.

The sun shines for the most part of the day, however, there are times when the sky is overcast.

Temperatures in Cancun in August

The earlier days of August carry on with temperatures from July. It’s usually hot, with a daily average of 28-29C (82-84F).

Towards the latter days of the month, temperatures start to drop a notch, but not enough to make you feel cold.

Despite the slight fall in temperatures in the last two weeks of August, it still feels just as hot because of the intense humidity.

If you’re visiting during August, it’s recommended to include tons of beach trips and cenote visits on your Cancun itinerary.

Humidity and rain in Cancun in August

As mentioned earlier, humidity is high during August so temperatures feel even hotter than they actually are. Almost all the days feel muggy because of humidity, which ranges between 70-90% depending on the day.

Since it’s the middle of Hurricane Season, rains are usually quick and intense during August. It’s also just a month before the wettest time of the year arrives, so chances of rain are higher, especially during the second half of August.

There are a total of 6 rainy days in August, and thankfully, they don’t happen to be consecutive.

Traveling to Cancun in August

June through October is the low season in Cancun, so prices are the lowest during this time of the year. August is also when the majority of US/Canadian tourists are back at home, chilling in the pleasant weather.

You’ll usually find people from Europe, especially the UK, visiting Cancun during August. There are almost always no crowds, so it’s one of the best months for families to plan their Cancun trip.

Prices for hotels and resorts are relatively low now, so if you’re looking for the cheapest deals, August can be a good month.

Since humidity stays high throughout August, it’s also the time when watersports, beach days, and cenote trips are the most enjoyable activities in Cancun.

The turtle hatchlings that started in late July continue on in early August. You can see baby turtles making their way to the sea, you can swim with whale sharks, and find lots of other marine life during your trip.

Also, keep in mind that in August Cancun beaches can be infested by Sargassum. If that is the case make sure you check out Isla Mujeres and Isla Blanca for pristine white sand beaches without any algae.

Events in Cancun in August

Apart from watersport activities and nightlife, Cancun sees a few big events in August as well. What are those? Let me tell you.

Fiesta de la Playa en Cancún

What’s the first thing that comes to mind when you think of Cancun? Your answer most likely was the gorgeous beaches.

If so, you won’t be surprised to hear that Cancun has a festival specifically for the celebration of its beaches.

The festival begins on the 11th of August and goes on until the 13th of August, with lots of parties and events for Cancun’s beaches.

Isla Mujeres Founding Day

The celebration of Cancun’s picturesque locations isn’t only limited to its beaches. There are so many other attractions in Cancun that are just as amazing.

One of these is the Island of Women (better known as Isla Mujeres) just a few miles off of Cancun’s coast. August 17 is devoted to celebrating this exotic island’s founding.

The festival is filled with music, parades, dancing, and lots of parties so make sure you don’t miss out on it if you’re visiting Cancun during August.

ZoukMX is a 15-day music festival in Playa del Carmen. It’s one of the longest celebrations in Cancun and involves workshops, dances on zouk (a genre of Caribbean music), and lots of partying. You can find the festival both at the beach and in the jungle nearby.

Assumption of the Virgin Mary

Just like the rest of the world, the Assumption of the Virgin Mary is celebrated in mid-August in Cancun. On Assumption Day, many churches display flowers for Mary.

Some towns and villages have processions devoted to Mary, with flowers and banners carried behind a statue of her likeness.

Cancun usually doesn’t have these processions, but I thought I would include it here for the sake of information.
