Overview
- Videos showing bright-blue surf at Mumbai’s Juhu Beach went viral in recent days, drawing late-night crowds hoping to witness the phenomenon.
- Bioluminescence arises when microscopic dinoflagellates emit light after water is disturbed, producing a blue glow through a luciferin-based chemical reaction.
- Sightings are sporadic and conditions-dependent, with better visibility on dark, calm nights and during specific seasonal windows.
- Similar displays have been reported at Havelock and Neil in the Andamans, Bangaram and nearby islets in Lakshadweep, Betalbatim in Goa, Padubidri and Mattu in Karnataka, Thiruvanmiyur in Tamil Nadu, and Aksa in Maharashtra.
- Online commenters are disputing the authenticity and scale of the Juhu clips, while a local outfit, Indo Kayak Juhu, is offering supervised kayaking sessions with limited slots.
