People stand on the beach at night to watch the waves glow blue due to bioluminescence.

It looks SO cool, but what is it? As the waves crash along the beaches in Florida this week, some are seeing a bright blue light. Paul Dellegatto from Fox 13 shared a photo to his social media snapped near Anna Maria Island that shows the bright blue glow in the water.

Is it something to worry about?

Crowds witnessing the phenomenon are enjoying the show. Is it something to be concerned about? Not at all. Unlike red tide or vibrio vulnificus that do cause health problems, this is nothing to worry about. It’s a natural thing. It’s called bioluminescence.

What is it?

The National Ocean Service describes the light as energy released by chemical reactions occurring inside (or ejected by) a bioluminescent organism. They say it’s used to warn or evade predators, to lure and detect prey, and for communication with other members of the same species. They say it’s kind of like the aquatic version of a firefly.

  • Dunedin Causeway/Honeymoon Island

    The Dunedin causeway is by far one of the cheapest options when it comes to beach days in Tampa Bay. It costs NOTHING to park at the causeway and enjoy the views of boaters, kayakers and jetski’s zoom across the bay. If you want that actual beach feel with soft sand and less rocks in the water, keep driving to Honeymoon Island. Parking is $8 per car and that’s all day. Let’s say you spend 5 hours out on the beach, that’s $1.60/hour.
