Early signs of Mumbai monsoons as Blue Button Jellyfish wash ashore at Juhu Beach

Mumbai continues to endure intense summer heat, although a recent spell of unseasonal rain in May brought short-lived relief. With the remainder of the month still ahead, residents are hoping for an early monsoon.

Meanwhile, the early appearance of Blue Button Jellyfishes, washed up on Juhu Beach, has raised speculation that the monsoon might arrive early this year. These marine creatures are typically sighted along Mumbai’s coast just weeks before the onset of monsoon and are regarded by fisherfolk as natural indicators of approaching rain.

Experts attribute their presence to strong pre-monsoon onshore winds, which sweep various floating marine organisms ashore. These jellyfish-like creatures drift with ocean currents and have little control over their movement. Between March and May, particularly after low tide, they are often pushed towards the shoreline by shifting wind patterns.

Scientifically named Porpita porpita, Blue Buttons are not true jellyfish but colonies of hydrozoan polyps. They measure roughly 2–3 cm in diameter and resemble small, transparent blue discs. While striking in appearance, contact with them may lead to itching, swelling, and skin irritation. Authorities advise beachgoers to take precautions in order to avoid getting stung by the jellyfish.
