The UK beach with seas that glow bright blue in the night -and how to see it | The Sun

A BEACH in the UK has become known for a rare natural phenomenon that makes its waters glow bright blue.

The strange sight is uncommon in the UK, with it mainly being seen in warmer climates such as the Maldives and Mexico.

However, every now and then, bio-luminescent plankton light up the waters in North Wales along Penmon Point in Anglesey.

The latest display happened just a few days ago, wowing those who had come specifically in hope of seeing it.

The sea appears to be glowing bright blue because of the waves crashing against the shore, which causes a reaction in the plankton.

When oxygen reacts with the liciferin and liciferase within the organisms, it creates the luminous ripples.

The same happens when people disrupt calm waters, creating an ethereal blue glow.

The best way to see the display is at night, by turning off all lights.

By then splashing in the water, it will be easy to see if they are present, as they should begin to glow.

They are completely safe to interact with, making it a fun and unique experience.

Places like Penmon Point host the displays sometimes between April and November, when the sea is warmer.

However, it might require some perseverance to finally catch a glimpse of the glowing waters.

Adam Thomas, Adam Jones and Rhys Caligari went out three nights in a row looking for the natural display before they eventually were treated to a light show.

Mr Jones told the Daily Post: "This summer we got lucky on the third night we were out. I can see Penmon lighthouse from my garden and from there it’s a 40-minute drive.

"I usually set off about 11pm and stay until 1am-1.30am, or longer if there’s activity.

“This time there is plenty of plankton but as the seas are so calm, they are slower coming to the shore. Luckily there were others on the beach who were throwing stones into the sea to disturb the plankton.”

In the past, Brits have also flocked to Port Talbot in south Wales to spot the rare glowing plankton for themselves.

Pictures of the phenomenon have also been captured at Puerto Marqués beach in Acapulo, Mexico.
