What is the real cause?

On hot days like today, the seas of Vietnam are still considered the most ideal destinations for tourists from near and far due to the cool climate. Like many others, the boy in the TikTok clip below also rewarded himself for a weekend vacation in the sunny and windy waters of Vung Tau. The story will not be worth mentioning if the boy does not discover this strange scene.

Posted 2 days ago, so far the clip has collected over 2 million views and thousands of enthusiastic comments from the online community.

Specifically, the 14-second clip recorded the scene of the water on a Vung Tau beach turning dull brown like coffee. As each wave reaches the shore, onlookers watch the color of the water fade. When viewed from a distance, they are dark brown in color.

Immediately below the comment section, TikTok users spoke about this strange phenomenon. Someone revealed that living for the first time in decades, they witnessed the seawater coloration of coffee like this. Many of you wonder where is the cause of the phenomenon, ultimately, does it affect visitors?

In fact, it is called the red tide phenomenon, which usually occurs in some coastal areas or estuaries of our country. This is the general term used for the seaweed bloom, which gives the water its characteristic red or brown color.

The red tide phenomenon is not uncommon in many areas of Vietnam and the world. It is produced by a kind of algae that blooms.

According to many comments from people living in Vung Tau, this phenomenon usually occurs only on certain beaches in the period from July to September each year. At this time, sea water often smells fishy. Better yet, if you come here this time, you have to be very careful, just choose clean beaches to bathe. When you see strange colors like in the video, you should stay away.
