This is the moment bright-blue neon lights are seen in the rolling waves at a popular beach in Tijuana in Mexico due to the absence of visitors during the COVID-19 lockdown.

The waves at Tijuana Beach in the north-western Mexican state of Baja California were illuminated with bioluminescence, the production of light emitted by marine organisms.

According to local media, the bioluminescence was reported on the beaches of Tijuana and Rosarito in the Mexican state.

The same marine organisms also cause the phenomenon known as red tide which has also been registered in Tijuana and along the US coast of California in recent days, according to reports.

During the day, the organisms are concentrated on the surface and they have mechanism to protect themselves from sunlight that causes the reddish brown colour on the water.

It is unclear how long the phenomenon will take place. On previous occasions, it lasted between a week and a month.

The beaches have been closed to prevent the spread of COVID-19, however some residents went out to witness the lights and the police had to prevent crowds from gathering, according to reports.

Last week, the bright-blue neon lights were also filmed in the southern Mexican tourist resort of Acapulco

According to the latest figures from the Johns Hopkins University, Mexico has registered 19,224 cases of COVID-19 and 1,859 related deaths.
