Mumbai, December 16: Is Iran witnessing "blood rain"? Multiple videos going viral on social media show the rainfall turning Red Beach's seawater on Hormuz Island in Iran "blood red".

"Video of the red beach during today's rain in Hormuz Island, southern #Iran," an X user said while sharing the breathtaking video showing the Red Beach turning crimson.

Did you know that Hormuz Island in Iran is also called Rainbow Island? So why does the water of the Red Sea turn crimson? It is reported that the Red Beach on Hormuz Island, which captivates visitors with its striking crimson sands and waters, is a result of high concentrations of iron oxide or hematite in the volcanic soil known locally as "gelack". The Red Beach, which is rich in minerals, is also a part of the so-called "Rainbow Island". 'Blood Rain' in Iran: Heavy Downpour Turns Red Beach on Hormuz Island Blood Red, Stunning Videos Surface.

Notably, the Red Beach on Hormuz Island turns crimson during heavy rainfall when the rainwater mixes red soil with seawater, thereby creating a surreal "blood rain" effect which draws tourists from across the globe. The rare and natural phenomenon also highlights Hormuz's unique geology, with the soil historically used in dyes, cosmetics, and even cuisine. Heavy rain turns the Red Beach water and sand crimson, thereby making the beach and the waves an unusual sight for visitors.

Why Does the Red Beach on Hormuz Island Turn Blood-Red?

Those walking along the shore usually come across areas where the sand glitters with metal compounds. It is worth noting that Hormuz Island's Red Beach turns strikingly crimson during rain due to the island's unique geology. The soil and surrounding cliffs are rich in iron oxide (hematite) and other minerals from layers of clay, carbonates, shale, and volcanic rocks that have oxidised over time, giving them vivid red hues. Iranian President Masoud Pezeshkian Refuses Handshake with Xi Jinping’s Wife Peng Liyuan at Beijing Parade, Video Goes Viral.

When heavy rain falls, it erodes these iron-rich sediments, washing them down the mountainsides into the sea, where they mix with seawater to create the dramatic "blood rain" effect - often called a natural phenomenon rather than anything ominous.
