Florida may be known for its beaches and sunshine, but it’s also brimming with natural wonders. And while freshwater springs and underwater coral reefs full of color and marine life spring to mind, one of the most magical sights can be found just a short drive from Miami.
Over on the Space Coast lies Merritt Island National Wildlife Refuge, about a three-hour drive from the Magic City. Its 140,000 acres are home to over 500 species of wildlife and 140 species of fish, but the real magic starts when the day turns to night. A countless number of plankton emit a stunning blue light on the refuge’s lagoon waters, better known as the Indian River Lagoon. They happen to make an appearance during the warmer months, which makes it the perfect opportunity to hop on a kayak and go cruising through the ethereal blue glow!
If you’re keen to see these bioluminescent waters, read on to learn more and find out when it’s best to spot this phenomenon.
What is bioluminescence?
According to NOAA, bioluminescence is light emitted by living things through a chemical reaction that occurs when they produce energy. Think of how fireflies or lightning bugs emit their glow.
It’s typically blue in color because this is the light that travels best though water, although bioluminescence can range from violet to green-yellow or red.
What causes the bioluminescence in the Indian River Lagoon?
Algae and phytoplankton are usually responsible for the blue, but specifically in the Indian River Lagoon, a group of phytoplankton known as dinoflagellates create the light we see. These organisms emit the glow whenever there’s a disturbance in the water. You’ll notice how every move made by your paddle, kayak or even animals below the surface becomes a mesmerizing spectacle!
When is the best time to catch this phenomenon?
While the best time to see bioluminescent waters varies, it’s a lot more common in the summer months since phytoplankton prefer warmer water and a higher salt content. Think June to October, with peak visibility during the darkest nights of the month. You can count on nights close to a new moon, so that moonlight does not reflect on the water.
If you can’t make it during the summer, however, don’t fret! The Indian River Lagoon is home to a second bioluminescent occurrence that takes place November through May. There’s another kind of organism known as Comb Jellies that usually wash ashore in the area and bring mystical light shows to the beaches of Florida’s Space Coast.
What’s the best way to plan a trip to the Indian River Lagoon?
While you can always visit the lagoon yourself, one of the best ways to get the full experience is on a kayak or paddleboat tour. Two of the most well-known are offered by BK Adventure and Get Up and Go Kayaking, where you can glide on a clear kayak for prime views of the neon water rippling below.
Every Miamian should see this mesmerizing natural wonder at least once in their lifetime! You can read more about it here.
