Iran’s Hormuz Island witnessed a dramatic natural transformation after heavy rainfall washed iron-rich soil into the surrounding sea, turning large stretches of the coastline deep red.
Footage circulating on social media shows rainwater carrying mineral-laden sediment from the island’s hills into the ocean, dyeing the water and beaches a striking crimson hue. The effect was especially prominent along the island’s famous Red Beach.
Situated in the Strait of Hormuz, the island is known for its naturally red soil, locally called golak, which contains high levels of iron oxide and other minerals responsible for its distinctive colour.
During periods of intense rainfall, streams of this soil flow from the cliffs into the sea, creating the vivid visual effect. Some onlookers have described the phenomenon as “blood rain” due to its appearance.
Often referred to as the “Rainbow Island,” Hormuz is celebrated for its diverse landscape, featuring shades of red, yellow, orange, and ochre formed through complex geological processes over thousands of years.
The rainfall-triggered colour change is regarded as a unique natural spectacle and continues to attract tourists and photographers eager to capture the island’s surreal scenery.
