We will explore scienctific, geographical and ecological data that explain ths natural phenomenon and we will share curious facts that will make you immerse yourself in them, you will not only be enjoying the beauty, but also understanding a little more of their natural magic.

What determines the color of the sea?

Although is seems that the sea simply reflects the sky, the truth is much more complex. The color of the sea is affected by several factors:

• The depth of the water
• The composition of the seabed (sand, coral, rocks)
• The presence or absence of phytoplankton and other  organisms
• Water purity (leve lof sediments and pollution)
• The incidence of sunlight

Each of these elements has a role in the way light is reflected and dispersed in the water, creating those characteristic blue and green tones.

Why is the Caribbean so blue?

1. Crystal clear water with little organic matter

The waters of the Caribbean, and especially the Riviera Maya, are relatively por in phytoplankton (small marine organisms that float in the water). Although phytoplankton is essential for marine life, it also has darker or greenish colors in water. In the Caribbean, the low concentration of these particles allows sunlight to penetrate deeper and reflect itself in a purer way, highlighting the blue tones.

2. White sand of coral orign

One of the main reasons why teh color of the water in Cancún  seems so bright is the fine white sand of its beaches. This sands is mostly of coral origin: it is composed of eroded fragments of coral and shells. Its light color reflects the sunlight upwards, which intensifies the colors of the water from below, making ot appear even lighter and brighter.

3. Shallow bottoms with coral areas

The region is full of shadow areas, ideal for snorkeling, When the sea is shallow and the bottom is composed of white sand or reefs, sunlight can penetrate, refloect and disperse more efficiently, creating that palette of blue, turquoise and green tones that you fall in love with so much.

The role of physics: how light creates the color of water

The sunlight is composed of all teh colors of the rainbow. When this light enters the sea, the water absorbs long wavelength colors (such as red, Orange, and yellow) more quickly. Short wavelength color (such as blue and green) disperse more and penetrate deeper into the water.

Therefore, blue is the color that we most see reflected in the sea. The purer and clearer the water, the more evidente this phenomenon will be.

What makes Cancún unique?

Cancún is not just a beach destination. It is a geologically privileged region. Here are some reasons that make it special:

1. Coral barriers

The Rivera Maya is part of Mesoamerican Reef System, the second largest coral reef in the world, after the Great Barrier Reef in Australia. These reef are not only home to thousands of marine species, but also influence the color of the sea. Corals, along with shallow water, intensify light blue and emerald green tones.

2. Cenotes and underground rivers

Under the Surface of the Riviera is one of the largest underground river systems on the planet. Manyo f these rivers Flow directly into the sea, providing fresh water rich in minerals that, when mixed with salt water, can create surprising optical patterns.

3. Tropical climate with high solar radiation

Thanks to its geographical location, the Riviera Maya receives a large aount of sunlight mosto f the year. The intensity of the sun also influences the clarity and color of the water, especially on clear days.

Curiosities about the color of the sea in Cancún

• The hue changes accordng to the time of day: During sunrise and sunset, the angle of the sun changes, which alters the color of the sea. In the morning, blue is usually softer, whilw at noon it is brighter.
• After a storm, the sea can change color: When it rains heavily, the water can drag sediments form the coast or rivers, making the sea look more cloudy and les blue for a few hours or days.
• The most turquoise tones indicate areas of shallow depth: If you see the water o fan intense turquoise color, you are probably in fornt o fan area ideal for swimming or snorkeling.
• The color of the sea is also part of biodiversity: By attracting tourists and divers, reefs and crystal clear waters help boost the conservation of the marine ecosystem.
