However, these pristine and white-sand beaches are more than just a place to relax during the day. Once night has fallen, lucky visitors watch the water begin glowing a bright blue, all thanks to a natural phenomenon. But, before you drop everything and book your trip, read our guide \u2018Thing to Know about the Glowing Beaches\u2019.<\/span><\/p>\n

The shores of <\/span>Sri Lanka and the Maldives<\/span><\/a> are already a dreamy destination for a trip, however, if you are wanting to include visiting a bioluminescent beach for the chance to see it yourself, <\/span>speak to one of our travel experts today.<\/span><\/a>\u00a0<\/span>[\/vc_column_text][vc_empty_space height=”50px”][vc_column_text]<\/p>\n

What causes the beaches in Maldives and Sri Lanka to glow?<\/b><\/h2>\n

Bioluminescence is the reason for these glowing beaches. Bioluminescence is the emission of light by a living organism. There aren\u2019t many species that have bioluminescence abilities. The Maldives and Sri Lanka are the hosts to one of these species: bioluminescent plankton.\u00a0<\/span><\/p>\n

The plankton glows when disturbed; this can be by waves crashing into the beach or someone throwing a rock into the sea. This disturbance causes the plankton to have a chemical reaction that creates light. A blue\/green light released by the plankton creates an otherworldly experienc<\/span>e and highlights the beauty and diversity of the marine life in the Indian Ocean.\u00a0<\/span><\/p>\n

Although it is possible to witness this wonder at all times of the day, it is most visible and memorable at sunset and nighttime when the bioluminescent plankton can show off their magic. <\/span>[\/vc_column_text][vc_single_image image=”23112″ img_size=”full” add_caption=”yes” alignment=”center”][vc_empty_space height=”15px”][vc_column_text]<\/p>\n

Is it safe to swim in the glowing waters?<\/b><\/h2>\n

Although it may look harmful, swimming in the glowing waters of the Maldives and Sri Lanka is generally safe. The glow is not harmful to humans. However, swimming in the dark has its own risks, like obstacles in the water and lack of visibility.\u00a0<\/span><\/p>\n

If you do go swimming while there\u2019s bioluminescence in the water, you should consider the impact of doing this on a fragile ecosystem. Even though they\u2019re tiny, these bioluminescent beauties play a vital role in the ecosystem. They act as a food source and help the ocean’s carbon dioxide level. With global warming, it’s crucial to preserve and maintain this small, yet mighty ecosystem.<\/span>[\/vc_column_text][vc_empty_space height=”15px”][vc_column_text]<\/p>\n

How long does the glow last?<\/b><\/h2>\n

It\u2019s hard to estimate how long this event can last. It can last a few days up to a couple of weeks; it just depends on how much plankton there is. But, there\u2019re many factors which can impact the length of time bioscience is in the water: water temperature, tides and weather all play a part in this.\u00a0<\/span><\/p>\n

It also varies from year to year and even beach to beach. Although technology is becoming more accurate, unfortunately, this stunning phenomenon isn’t straightforward to predict.\u00a0<\/span>[\/vc_column_text][vc_empty_space height=”15px”][vc_column_text]<\/p>\n

When\u2019s the best time of year to see the glowing beaches?<\/b><\/h2>\n

It’s not always easy to predict when the glow will appear. Experts are trying to make it easier and more accurate which means hopefully it\u2019ll be easier to see in the future. Luckily for now, if you\u2019re planning a trip to see it yourself, there\u2019re some times of the year which are more likely than others.\u00a0<\/span><\/p>\n

The most likely time is April to November, but within that,\u00a0 the most action tends to happen in September and October. The water temperature then is perfect for the tiny organisms to grow.\u00a0<\/span>[\/vc_column_text][vc_empty_space height=”15px”][vc_single_image image=”23111″ img_size=”full” add_caption=”yes” alignment=”center”][vc_column_text]<\/p>\n
