When diving with a new buddy, it is always worth reviewing hand signals to make sure there is no confusion when you are underwater. Some divers develop their own signals outside of the basic hand signals, so make sure you know what you're both saying before you go under!
Scuba diving in Mexico can be a very varied affair due to the fact the pacific ocean is on the west coast and the massively different Caribbean Sea. Mexico is home to some of the world's most beautiful Cenote cave diving experiences and the Yutacan peninsula allows you to dive the Great Maya Barrier Reef, which stretches 200 miles (320km) from the nortern tip of the peninsula down the Belize coast to Honduras. The Great Maya Barrier Reef is home to a fantastically diverse range of species and is the second largest reef in the world after the Great Barrier Reef.

The Mexican Climate
Almost all of Mexico enjoys sunny weather for a large part of the year. Each region of Mexico will have contained climates due to the varied topography of the land. You have the Sierra Madre mountain ranges that extend along most of each of the coastlines and the Gulf of Mexico, Caribbean, Pacific Ocean and Sea of Cortez all have a dramatic impact on the climate.

Where are the Mexican Cenotes?
The Yutacan peninsula is home to some of the world's most famous and amazing Cenotes ("sink holes"). Cenote diving offers a very unique experience in terms of marine diversity, due to the fact that a lot of Cenotes are cut off from the open seas and oceans. This makes them closed ecological systems, which over tens of thousands of years have evolved fish and plantlife that you won't find anywhere else in the world.

It is important to realise that some cavern and cenote diving have areas where there is no open water (i.e. water with air above it). Cavern diving presents new challenges, so for open water caverns, you'll need to have the dive lead by a qualified diver and if you're attempting diving of fully submerged cave, you should be a qualified cave diver to ensure your safety and the safety of others on the dive. Cave diving can be dangerous!
