Why is Vaadhoo Beach in Maldives glowing?

Vaadhoo is the island known as the Sea of Stars, but it is not Thoddoo, and a glow is never guaranteed. We corrected where it is and what is really known.

Where Vaadhoo is

• Vaadhoo is an inhabited island at the southern tip of Raa Atoll, about 194 km from Malé. It is about 1.45 km long and 0.4 km wide and had 452 residents in the 2022 census.
• It is not on Thoddoo. Thoddoo is a different island in another atoll, so a visit to Vaadhoo is a separate trip.
• Viral photos from 2013 were traced to a beach on Vaadhoo. Some sources confuse it with a resort named Vadoo, far to the south, where a notable glow was not recorded.
• The first guesthouse on Vaadhoo opened in 2024.

What makes it glow

• The glow is attributed to phytoplankton or dinoflagellates. Individual organisms flash for less than a second when the water is disturbed, and ostracods have been credited with longer glows.
• We have not found a scientific study that names the exact species at Vaadhoo, so we do not state one.
• The glow shows when waves or swimmers disturb the water, and is easiest to see on a dark beach.

When to go and what to expect

• Travel sources most often say about June to October, with new-moon nights the darkest. One source argues for the dry season, and we found no scientific data, so treat any month as a chance and not a promise.
• No visit guarantees a glow. Staying several nights improves your chances.
• Avoid torches and phone lights on the beach, and do not touch or collect anything in the water.
• Vaadhoo is far from Thoddoo, so we do not promise a visit from here. Ask us what is possible for your dates. When plankton glows
