Cyclone Narelle Turned Western Australia's Sky Blood-Red in 2013

In March 2013, Cyclone Narelle struck Western Australia with force, leaving a trail of damage and an unusual natural spectacle. The storm, far stronger than Cyclone Bianca in 2011, brought fierce winds that scattered red dust across the region. Residents at Shark Bay Caravan Park witnessed the sky turning an eerie shade of red as the cyclone raged on.

Cyclone Narelle made landfall near Onslow on 20 March as a Category 4 system. Its winds tore through coastal areas, causing power cuts and structural harm. Unlike Cyclone Bianca, which brushed past Western Australia in February 2011 with little impact, Narelle's effects were severe.

The storm's winds picked up vast amounts of red dust from Australia's arid interior. This dust formed through the slow breakdown of iron-rich rocks under extreme heat. As the particles scattered in the air, they created a striking red hue in the sky—a phenomenon known as Mie scattering. A similar event had occurred in Indonesia's Jambi province in 2019, though there it was caused by wildfires rather than a cyclone. Narelle's reach extended beyond Western Australia, affecting three states and territories. This had not happened in over two decades, marking the storm as one of the most widespread in recent history.

The cyclone left behind damaged infrastructure and a rare visual display. Its winds carried iron-rich dust hundreds of kilometres, turning skies red in places like Shark Bay. While Cyclone Bianca in 2011 had been a point of comparison, Narelle's intensity and broad impact set it apart.
