Mumbai's Juhu Beach Glows with Mysterious Blue Waves
10 Feb
Summary
- Tiny marine organisms cause the sea to glow blue when disturbed.
- Bioluminescence is a natural chemical reaction within living organisms.
- This phenomenon has been observed before along India's west coast.

Recent videos capturing luminous blue waves at Mumbai's Juhu beach have captivated social media users. This captivating spectacle is attributed to a natural occurrence known as a 'blue tide,' a result of bioluminescence. Microscopic marine organisms, specifically dinoflagellates, emit a blue light when agitated by ocean movements.
Bioluminescence is the production of light by living organisms through a chemical process. This phenomenon, observed in various sea life, can range in color from blue to green. While these glowing waves have been previously noted along India's western coast, their appearance is infrequent and dependent on environmental factors like water temperature and nutrient levels.
Although generally harmless, extensive blue tides can signal distress within marine ecosystems. Factors such as elevated sea temperatures and pollution can contribute to their formation, underscoring the delicate balance of the ocean environment.
