Sea sparkle lights up beaches of South Holland

The warm weather combined with very little wind is a rare phenomenon in itself in the Netherlands. But now, nature has added some extra magic to our summer evenings — we’re talking about sea sparkle!

Sea sparkle, which can now be seen all along beaches in the southern part of the country, is a natural phenomenon that makes tiny single-celled organisms light up in beautiful blue colours at night. Sounds magical right? Well, a very specific science is behind it!

Perfect conditions

Under other meteorological circumstances, sea sparkle would sit at the bottom of the sea. However, warm weather makes the organisms multiply excessively and when the sea is calm, they float to the surface.

And then — magic happens! Once the weather conditions are right (as they have been in the Netherlands this past week), sea sparkle lights up at night when the waves move. ✨

It’s lit!

This process is known as bioluminescence — a chemical reaction that, instead of converting energy into heat, turns it into light. In other words, when the waves move due to a nice summer breeze (or because you eagerly wave your hands around in the water to see the phenomenon), the sea lights up!

Aside from sea sparkle, some jellyfish, frogs, fish, insects, and mushrooms can also light up with bioluminescence. Cool ?

Where can you see it?

The sea sparkle is expected to remain visible along almost the entirety of the Dutch coastline, provided that the weather stays the same. Currently, it is most visible in South Holland, reports Omroep West. People have already flocked to the beach to see this amazing natural phenomenon.
