Cancun Travel Tips for August and July

These tips will help you enjoy your Cancun trip in August and July. Once you understand the weather and what you can do during this time, you’ll have a memorable trip. 

1# High Season 


August and July aren’t part of the high season (December to April). Visitors are usually wary of storms and less sunlight, making it a period with fewer crowds at the beach. You’ll find most Mexican families in the area in July; hence you’ll have to plan and book your accommodation and activities earlier. 

2# Prices

The prices of food and accommodation in Cancun are fairer in July and August because of the lesser traffic. During the peak season in December, you’ll find higher prices which can affect your budgeting and planning. Investigate and compare prices and choose places that fit your financial budget and expectations. 

3# Sargassum

Cancun Seaweed

Suppose you intend to swim and enjoy your time at the shores of the sea, to look for accommodation areas in Costa Mujeres or Isla Mujeres with less seaweed. In July and August, Sargassum (seaweed) is at its peak. This seaweed gets deposited at the shores, decomposing, and rots, giving a bad smell. 

Unfortunately, Mayans don’t have a foolproof method of dealing with seaweed. Ensure you get a good area that has less seaweed. Check out different areas to reach clear waters where you can swim or watch the sea life comfortably. Alternatively, you can book a hotel or apartment with a good swimming pool that you can dunk into on the hotter days.

4# Mosquitoes

The Mayan jungle has pesky mosquitoes. When swimming in crystal clear areas like cenotes or while lying on the beach, be careful and wear your clothes once out of the water. 

Using mosquito repellents poisons the cenote water and is thus not advisable. Look into alternative methods of protecting yourself, like using pills in such areas.

5# Plan Your Activities For The Morning

It usually rains less in the morning!

When planning your Cancun trip, jot down the activities you’d like to do in the area. It will help you plan each day effectively which actions you will take.

You’ll know whether there will be more humid or rainy days and plan accordingly. It also helps you choose appropriate clothes for the day. Areas like cenotes will require lighter but more covering clothing. Consult your guide or agent to find out how to maximize your day. Don’t have too many activities in one day as you’ll not enjoy every action.

You can spend a couple of hours to a full day out in the waters as you enjoy being surrounded by marine life. You can carry your cameras and snacks to spend longer in the water. Inquire about different islands and which will best suit your expectations and adventure. Isla Mujeres is among the best ones you can visit.

8# Turtles

You’ll find many young sea turtles in the water adapting to their new aquatic life. Turtles are an endangered species in Mexico. Hence, some resorts take protective measures to collect and protect their eggs. The end of July sees most turtles hurdle up at the shores for mating. 

Resorts and different groups of people usually take time at the end of July (the nesting season) to hatch the eggs as they take their first steps into the sea. You can inquire from the locals to discover where you can witness this critical step in the turtle life cycle. 

You can also plan for night diving to observe the groups of sea turtles as they prepare to rest. This beautiful view can be an excellent way to end your day.
