A striking video of a beach in Iran turning blood red amid torrential rain has taken social media by storm. While some speculated about extreme weather or mysterious phenomena, the real explanation is grounded in science.

The viral video

Originally posted last month but gaining traction recently, the clip was shared by a tour guide on Instagram. The translated caption reads, “The famous Red Beach of Hormoz welcomes heavy rain. Tourists are left in awe!” The video shows crimson soil washing down to the shore, mixing with the sea, and giving the waves an eerie red glow.

Where is this beach?

Located on Hormuz Island, known as the Rainbow Island in the Strait of Hormuz, the region is sparsely populated and remains largely undisturbed.

What causes the red tide?

According to the Iranian tourism board, the phenomenon is due to high iron oxide content in the soil. When rain washes this mineral-rich soil into the sea, it creates a dramatic reddish hue.

Is the soil valuable?

Locally known as gelack, this red soil is highly prized in industries, cosmetics, dyeing, ceramics, and even cooking—it’s used in making jams and sauces!

A must-visit destination

With its ever-changing soil colors and glittering sands, Hormuz Island is a breathtaking attraction, especially at sunrise and sunset.
