The World’s Strangest Natural Phenomena and Where to Find Them

Our planet is filled with natural wonders that stretch the imagination—spectacular displays and phenomena that seem almost otherworldly in their appearance and behavior. From luminous waters that light up the night to stones that glide across desert floors, there’s just something about these phenomena that never fails to amaze us. And as nerdy as that sounds, they also make me feel deeply curious and motivated to learn the science behind these things. And that’s exactly what I did in today’s article! So, if that’s something that interests you as well, join me on this journey through the world’s strangest natural phenomena and where to find them.

Bioluminescent Waves — Vaadhoo Island, Maldives


Okay, I’m not saying that you need any particular reason to visit the Maldives besides their stunning beaches and pristine waters. However, if you do need some extra motivation, then you’ll be glad to know that the Vaadhoo Island on the Maldives offers something uniquely mesmerizing — bioluminescent waves. On dark nights, these waters light up with a mysterious blue glow, a result of bioluminescence caused by marine microbes known as dinoflagellates.

These microscopic organisms emit light when agitated, as a form of defense mechanism to thwart predators or to lure prey. The chemical process involves luciferin (a molecule) and luciferase (an enzyme) interacting in the presence of oxygen. While the science behind it is pretty fascinating as well, the breathtaking light show that you would be able to witness is even more impressive. This phenomenon is not only a gorgeous tourist attraction, but also the perfect opportunity to explore your inner scientists and learn more about marine biology.

Catatumbo Lightning — Lake Maracaibo, Venezuela

Let’s talk about another natural light show, this time located at Lake Maracaibo — Catatumbo Lightning. This is, arguably, one of the most unique meteorological phenomena in the world. This area, where the Catatumbo River meets Lake Maracaibo, experiences an astonishing 140 to 160 nights of lightning each year, with up to 280 flashes per hour at its peak. So, if you’re afraid of thunderstorms — this absolutely isn’t the place for you. But if you’re into them like I am, then this could be such a unique thing to experience. The lightning storms are so intense and frequent that they have entered the Guinness Book of World Records for the highest concentration of lightning. Even through history, sailors have historically used the storms to help them navigate through this area.

The scientific explanation behind this relentless storm involves a perfect set of geographic and climatic factors. The lake is surrounded by the Andes Mountains and other high ridges, which trap a variety of winds that converge over the warm, humid area filled with evaporating lake water. In the evenings, the cooler air from the mountains pushes down, clashing with the warm, moist air rising from the swampy region rich in methane. Which is basically the perfect setup for a thunderstorm to hit! Researchers also suggest that the high methane content from oil fields below and around the lake could be increasing the lightning’s frequency and intensity.

Rainbow Eucalyptus Trees — Maui, Hawaii, USA


If you’re a three enthusiast, then we have something for you too! The Rainbow Eucalyptus, or Eucalyptus deglupta, is one of the most visually striking trees in the world, known for its brilliantly colored bark. Native to the Philippines, Indonesia, and Papua New Guinea, this tree thrives in tropical forests where high rainfall and humid conditions are more than common. The bark of the Rainbow Eucalyptus sheds annually, peeling away in strips to reveal a bright green inner bark. This green then gradually matures through a spectrum of blues, purples, pinks, and oranges as it ages and is exposed to air, sunlight, and varying weather conditions. The end result? Arguably the most stunning tree that this world has to offer.

I would highly encourage you to do a quick Google research yourself. You’ll see how this stunning tree almost resembles a watercolor painting. The gorgeous colors are due to the presence of tannins, which are natural pigments that react differently as the bark matures. But these trees do so much more than just create a rainbow of colors. They also protect the tree from harmful bacteria and fungi, making it exceptionally well adapted to its environment. On the island of Maui in Hawaii, you can find these trees along the Hana Highway. Which is a particularly popular stop for photographers and nature lovers alike. Beyond their beauty, these trees also play a critical role in their ecosystems. They provide habitat and food for a wide array of species.

Raining Fish — Yoro, Honduras

Each year, the small Honduran town of Yoro witnesses a baffling meteorological event known as “Lluvia de Peces” (Rain of Fish), which has occurred since the 19th century. Following severe thunderstorms that typically develop between May and July, hundreds of small, live fish are found flapping on the ground, much to the astonishment of residents and scientists alike. Local folklore claims that this event is nothing less than a miracle by Father José Manuel Subirana, a Spanish missionary who prayed for three days and three nights asking God to provide food for the poor people of the region. And honestly, this interpretation of this phenomenon is really uplifting.

However, science is claiming something else. The most popular scientific explanation involves waterspouts or tornadoes, which are thought to suck the fish up from rivers or the ocean and deposit them over the town as the storm abates. However, some scientists are skeptical of this theory, as the species of fish typically found after these rainfalls do not correspond to those from nearby waters. Another theory suggests that seismic activity might force groundwater to the surface, bringing underground aquatic life with it. Despite various investigations and theories, there’s still no definitive explanation. Which, of course, makes the Rain of Fish an enduring mystery and a highlight of local culture with its annual celebration in the “Festival de Lluvia de Peces.”
